ok so my disco wouldnt take a charge earlier from my hand pump, so i went to pull the the foster fitting on the airtube to check for a clog, my gauge read 250psi wich is empty from my past use of this rifle when i depingged it. i thought it was empty.. i was very wrong.. 1900psi releasing in seconds in my face.. the wrench, foster fitting my my tubing used for the deping all went through thedry wall on the ceiling of my living.. i have no hearing in my right ear and my vision in my right eye is blurry.. nothing but air hit me in the face and i am now headed to er to get checked out.. i have no clue as to what went wrong.. the gauge said it was empty.. i dry fired the rifle and no air came out...
-
In the er now, thankfully I live 3 blocks from a hospital.. my vision is clearing up thank god, still have a ringing in my right ear with no hearing in my right ear cept for the ringing...
This was my fault, got to comfy and skipped the whole stick a screw driver in the degassing hole.. if I had done that id have felt the amount of pressure needed to degass it and would have known it was still under presure
-
Man so glad to hear your OK ! Have you considered a springer ? :P
-
Lol I will be taking a break from pcp's.. plan to completely tear down the disco and find out why my guage was saying it was empty and why when dry fired it didn't shoot any air
-
Wow! Glad you weren't hurt badly!
-
(http://i779.photobucket.com/albums/yy79/mizke/pcpholes.jpg)
far left hole was the wrench middle hole is the foster fitting and the 3rd hole i have no clue but assume it is the tubing for when i depinged it
had a couple of windows open and thankfully a neighbore was outside and heard it, they came knocking and i asked for a ride to the er
-
lol might not have been a massive failure but to me it was.. i was in the dinning room sitting in a chair, after it pop i was sitting on the floor of the kitchen up against the stove.. it didnt knock me over there but i dont remember getting up and walking to the kitchen
well as i said i screwed up, even tho when dry fired i should have tried to degass it that would have told me it was still under pressure... so let this be a lesson to every one double and even triple check before you start undoing anything.
im not in any kind of pain, other then a little blurry vision and ringing in my right here oh and the not hearing anything in my right ear im fine.. just shook up from it but i am still going to get checked out.. no blood from my ear so i dont think i did to much damage.. maybe about the same a a large fire work going off a few feet away
-
Glad you weren't hurt badly.
I all ways use a long rod i made to degas with.
Never trust any thing when working on ag,s.
-
thanks guys, at least i know its degassed now for when i get home..lol gotta go buy a sheet of dry wall and get some to the texture for the ceiling
-
wow, I'm glad all the pieces went straight up and not towards you. I hope you fully recover quickly. Keep us informed on your progress.

Was Jager involved.......???? ??? ??? ??? ??? ???

Was Jager involved.......???? ??? ??? ??? ??? ???
nope stone cold sober... just made a stupid mistake by not trying to degass with a screw driver first
i wont be getting a tank setup anytime soon, and i need to order a new guage and fitting for the airtube so there is about a week to get delivered maybe longer with the holiday coming up..
just got checked out, they put a dye in my eye and then looked at my eye under a black light and there is physical damage other then the air that hit me.. i didnt take a full blast to my face. doc said if i had blown my ear drum i wouldnt be able to hear out of it and that the ringing should decline over night if not through out the day tomorrow. he checked with his cell phone if i could hear out of my right ear by putting a ear plug in my left ear and i could hear enough to understand what the lyrics where in the song he played.. reffered me to a ear doc for tomorrow to double check that no long term damage was done...
my hands are still shaking from this and my heart is still beating rather hard. but cant let this freak out to the point to where i wont shoot my disco but it will be a little while before i pressurize the airtube even after getting the parts from crosman.. lol i was writing down part numbers while waiting in the waiting area to get checked out.. doc made it a point to tell me how lucky i was because the wrench or fitting if it had hit me in the eye or head would ahve lodged in em and the tubing at that pressure might have been able to crakc my skull and deff would have had the energy to lodge in my eye socket..
-
glad it wasn't an worse. hopefully the hearing will return with minimal loss. good thing didn't get a small piece of debris out of the air tube. when i took my mrod down the 1st time it had a lot of aluminum shavings from almost stripped out gauge block assembly. looked as though it got cross threaded. once again glad your ok. and didn't lose an eye ;D
-
I'm glad it wasn't worse. But I'm also glad that you see it for what it was; a mistake. It should serve as a reminder to us all that HIGH PRESSURE IS NO JOKE.

amen, all tho something inside the disco failed.. i stopped shooting last night at 1900 pis but now that i think about it it was filled to 2000 when i started shooting and i shot about 10 shots and it only red 1900psi... should have been the fist sign there was a problem.. but i dry fired it several through out the day after installing the challenger stuff and no air came out, just a click of the hammer striking the valve and the guage said it was empty..
-
still want the pcp?
thats kinda the reason i didnt wan to get a pcp besides cost, have to rely on WAY too much stuff.
anyways, glad youre ok.
-
ya i still want the pcp just going to be awhile before putting pressure back in it
-
Mike I'm very glad to hear you are OK as this could have been real bad! As Richard said WE ALL NEED TO PAY CLOSE ATTENTION TO WHAT WE ARE DOING AT ALL TIMES WHEN WORKING AROUND HIGH PRESSURE AIR!
IT CAN BE DEADLY Mike just used one of the cats nine lives!

Really glad to hear you're OK mike. It's always the "stupid mistake" that gets you. I was hydraulics/pneumatics on F-4 Phantoms and worked with 3,000 PSI systems. I saw the results of a number of "stupid mistakes." One resulted in one of our sergeants torn open from butt to belly button with a broken thigh and a broken hip because we took a "short cut."
Climb back on that horse as soon as possible. The longer you wait, the more timid you'll be. (Only after you've completely checked out the problem of course.) Say a prayer of thanks this Thanksgiving.
If it was me, I'd have to pick up a new pair of skivvies too:-D
-
i got a little bit of shock or vertigo going on.. slightly light headed, heart is still beating harder then normal.. its either shock, vertigo or just the realization just how bad this could be.. i almost threw up in the er y stomach start knotting up.. called my grandmother who was a nurse for 30 something years.. she came by and checked me out her self even tho i went to the er...
-
Didn't your Discovery come with the thread in degas tool??? I had two of them and both came with the degas tool that threaded in the 10-32 hole in back to degas when switching from Co2 to HPA and vice versa did they cost cut that out of the box??
I thought they gave you one since you said "pump the rifle up for some test shots since i degassed it for the install" ... "after 4 or 5 pumps the pump pressure reads just over 2000psi"
I guess this is a lesson for all of us ....degas and double check everytime
Thank goodness ur OK at this point
-
i degass by shooting down to about 6 or 700 psi and then stick a small screw driver in the degassing/power adjuster hole and pushing untill it dumps the air..
thing is if i would have tried i can push hard enough to degass with over 1200psi in the rifle.. id have known in a matter of seconds it was still under pressure..
im about to go pull my box down, maybe i missed it in the box i think you get the degasser if you buy the disco with out the pump..but if you get the pump and disco combo it comes with no degasser..
still my guage was sitting at 250psi everytime ive cracked the airtube open for the depinger.. the gauge when i start working early said 250psi.. last night it said 1900 after i got done shooting.. a fualty guage was the reason that i thought the airtube was empty
-
looks like this...
and you know else scares me is all those rifles that put the gauge on the end of the air tube like my FX, AA S200 etc. I always wondered why you would put the gauge where the customer will most likely be pointing a rifle barrel toward their face....seems sort of like a really dumb call on the engineers parts don't it???
-
Wow....that's very scary. Thank goodness you didn't get hurt even more.
-
Wow, you were lucky those parts didn't hit you in the face or anywhere on the head. Never trust that little gauge! Take all precautions.
Was your Disco stock, or modified? Just curious.
Glad you are doing ok. The vertigo is normal because of the shock to your ear drum. Could have very slight inner ear damage. I have inner ear damage and I am almost 1/2 deaf in 1 ear and 25% on the other. It happened when I went to watch the Blue Angels air show (F-18's). I decided I was going to be cheap and not pay to get into the airport because I knew the area well. I parked my car on the side of the road on a hill overseeing the entire airport. Well what do you know? Six (6) F-18's all over a sudden appeared <100ft over my head with full after-burners causing me to temporarily lose >50% of my hearing. All I heard was the supersonic boom and those jet engines without warning. It was the loudest thing I have ever heard in my life, like thousands of decibels. Nothing close to 1900psi being released. They were flying at the speed of sound or faster and you just didn't have time to prepare or cover your ears. For good measure and to make sure the damage was good & permanent I stayed to watch the show, when everyone that was parked there with me took off holding their ears and their kids crying "mommy my ears hurt". 10min. later after watching their acrobatics and superb flying and coordination, I lost them again. I started walking to my car thinking they may show up again, when they did before I got to the car! They were over my head again out of the "blue" (get it? hehe) without warning and full after-burners. I covered my ears but it was too late and not enough. I had bad vertigo and a headache for a few days after that, actually about 1 week. My hearing recovered mostly but kept deteriorating slowly over the next few months and years because I had regular hearing tests to monitor it. That was >10yrs ago and my hearing is still getting worse. Doc says I will be wearing a hearing aid in a few years. I still have a little vertigo and many times feel like I am not walking straight. Have never really felt "normal" since that day.
I don't mean to scare you because I think your case is a lot MILDER than mine. It felt like my body was going to explode when those F-18's flew by so very close. And that was times six - 6 aircraft. I think you are thinking of the severity of the accident and what could have happened, that is making your heart race and want to throw up. There is not much at all they can do about any hearing loss but you will get your hearing back, and the ringing will go away very soon, so don't worry about that. I am pretty sure you do not have any permanent damage. I say this because when I was 18-19, my stupid cousin discharged my Marlin 30-30 in the basement of my parents' house (without my permission and shot a big log we kept down there as a chair) and both our ears were ringing. Our hearing was "muffled" for a couple of days but it all went away and we had our hearing checked and everything was normal. The sound shock waves caused mirrors to fall off the walls in the room. That's how bad it was. Firing a high-powered rifle in a closed room is just as bad I think as what you went through, except for the air in the eyes.
Anyway, good luck and I don't blame you for not wanting to fill up the Disco any time soon. That was a dramatic experience you went through and it will take some time to recover from it psychologically.
-
ya i know what the degasser is and there wasn't one in the box... ringing in my ear is letting up some
got the disco half way stripped down but the stupid little breech screw is stripped out.. i even put a clamp on the breech to sandwhich it down for removing that screw..
found the cause of the gauge problem.. a piece of shredded oring was plugging the gauge port hole.. wonder what I'm going to find in the valve once i get the breech off..
any one got any ideas on getting the breech screw out ? figured id do this tonight to keep me busy and focused on something easy so if i have any problems physically i will notice them more doing something like this i think lol..

i think ur hitting the nail on the head man, a day or 2 and i should be good.. the dizzy and light headed feeling has start letting up, got a minor head ache but since i get migrains behind my right eye once or twice a week a normal head ache is no sweat dont even need a excedrin.lol... thats crazy about the f18's, but by sharing that story i think you saved the hearing of at least one person at a future air show.. if that was my cousin id have shot him in the rear end for that one..
i keep telling and reminding myself how well and safe the disco was before this and that this is in fact my fault not the rifles fault, keep thinking all the times i filled her up to 2000psi with no problems.. actually this would be the first issue with my disco.. i dont feel scared of the gun, but i will prolly spend 10 minutes in the future every time i need to work on the internals triple and quad checking that its degassed..
tomorrow im ordering a new foster fitting since ya the one in the attic is prolly lost under insulation lol.. as well as i need to find a new guage.. that when at 0 psi it says zero and its made by a company that builds high quality gauges...
thanks for the kind words guys, this is by far on of my top scary &^^& to happen to me. im going to the ear doc tomorrow for a hearing test and then again a week later. but i think what saved me from taking something to the head was that i had the barrel between me and the airtube.. that also might might have just moved the air just enough to save me from getting hit worse in my eye.. either way the disco is being tore down to id the problem..

thats not worthy they cost cut it out.....
I hate those .050 allen wrench screws......I have seen over on the Crosman Green Forum various ways to attack a stripped one

Wow, Mike I am glad you are not hurt any worse than you have reported. High Pressure air is a dangerous combination and as you can attest all it takes is just a momentary decision to change from safety to danger. I think you have identified the mistake you made and I appreciate your taking the time to share with the GTA family not only what did happen but what COULD have happened. It could have been much worse but thank God, it wasn't.
I hope and pray your hearing will return fully and that you will continue to feel comfortable shooting your airguns. Again, I'm glad you're okay brother.

id say it was mildly modded
long probe bolt
mrod trigger
challenger hammer
challenger striker
challenger trigger guard
depinged ( tube is now somewhere in the attic..lol)
its all drop in bolt on stuff, no custom work, yet...

thanks man, the way i see it. pulling a stupid move and hurting ur self and then sharing what you did wrong and what happened to you is a way of preventing that from happening..
im willing to bet some one is gonna read this and then in a month need to crack open the airtube and throughly make sure its degassed just from reading this
head ache is still there, ringing in my ear is down to about 50% of what it was and while i have some hearing starting to come back.. the redness in my eye is gone cept for 2 or 3 spots where it looks like a little red dot.. no swelling.. i got away from this very lucky and funny thing is i was having by the worset day ive ever had in a very very very long time.. i should have just left the disco alone untill tomorrow and then maybe my mind would have been focused on the disco and not thinking about other stuff..

I'm shocked I didn't dirty myself up when the fill adapter popped off the airtube. Best thing to come from this event is a much healthier respect for hpa.
Very very glad I wasn't living in a apartment and had this happen.. idk if the fill adapter have packed enough punch to go through the floor of an apartment but if it did it could have hurt some one...
-
Glad to hear thay you are ok. I know that i will be more cautious... now. Hope you recover 100%.
-
Boy you young guys protect your hearing, you will miss it , I know , 60's rock band and shotgunning with no ear protection when I was young. Might save your kids laughing at you getting what you hear wrong when your old ;) I would like to thank the guy that came up with closed captions

Glad your ok bro it could have been much worse, PCP's can become scary real fast. Ed

Geez!! That's scary, I hope your ok

Mechanical devices can and do fail so if you trust them you will continue to pay a price. Use this as a reality check that says "if it is mechanical it is suspect. If it can fail it will and if you look at the worst case scenario in all things pressurized you will be far better off".
The sad thing is we should all be able to learn from your mistake but it is not like that. You got the pain and that is a great memory stimulator. Use it to make you a safer shooter in all aspects.
They are always overcharged, loaded, failed safety/trigger/valve etc etc.
I've worked with pressure all my life. When I was 8 years old my grampa shot a 10oz Crosman tank through a cinder block wall with only a 3 foot run through a close fitting pipe at the wall. All my cousins and I were impressed.
I've you don't respect pressure there will be a penalty down the road. You got lucky and if you learn by it you got smartened up. You need to avoid getting complacent with PCP, not avoid using it.
Double, triple or quadruple check but don't assume anything except WORST CASE SCENARIO!
Then you are part of the solution rather than part of the fault.
-
John said "After breaking the fill valve loose (32nd or so of a turn) and then all you needed was light finger pressure to remove it? If you need more force there is air inside (this applys to all airguns)."
Ditto that to co2 guns also. The retainer plug on my AR2078 is nearly impossible to unscrew with even a small amount of co2 left in the pressure tube. Insert the de-gasser tool and voila, she comes of with no resistance except the o-ring.
-
Wow Mike, hope you recover okay brother. Be careful playing with BB guns!!!!
Happy Shooting!!!!

I'll try not to say to much here.
You changed some striker(hammer) parts, then "fired it" but no air came out?
Just like most clock's. gauges do not talk, so it cant tell you it's empty.
Air gun gauges (all of them period) are for a general ref. only, you wont find a small one that works well enough to count on. Gauges only read correctly (even top dollar ones) in the middle of the pressure range.
After breaking the fill valve loose (32nd or so of a turn) and then all you needed was light finger pressure to remove it? If you need more force there is air inside (this applys to all airguns).
Say the firing valve was broken-wouldnt fire but darn sure had air in it- you would only be able to bleed the air off using the fill valve. Hook up your pump/tank, fill until the valve IS open then bleed air off SLOWLY, if you JUST crack the bleeder it will drain the entire air-tube.
Think I'll stop there, except glad you got lucky.
John
Yep.. I didn't want to say "too much either", or ask too many questions because of the injuries and recovery period.., but Mike knows what he did wrong, and how he could have done things differently now. I have never owned a pump, but "not being able to pump air into the gun" to me means that you should not be able to push down on the pump, or in the least hear a leak.. If it was pumping normal, then that means air was going into the gun's tank until it got much harder to pump near the maximum fill pressure. I would feel a lot more comfortable with a pump system or hose that has a secondary gauge on it to double-check the pressure and make sure it matches that of the Disco.
Whatever the case might be, the fact is, it takes an enormous amount of force to unscrew or remove a fill valve/adapter from any gun or fill-station/hose, like John said, when it is still pressurized, and the air has not been bled. If it's very difficult to unscrew a fill valve or any device attached to pressurized air, that should be a major clue that there is still air in the tank..
If you run into any kind of problem with a PCP and you are not sure how to correct it, PLEASE get on here or the Shop Talk/Mods Gate and ask for HELP first. We will make suggestions on how you can proceed and what to check in what order.
This is when I really like the design of the Talon/Condor. You can unscrew the tank from the gun/frame in 3-4 seconds and troubleshoot them separately. This does not unscrew the valve or fill valve/top hat, etc., just removes the entire tank intact in a couple of seconds . This also gives you peace of mind when working on or upgrading components in the gun, with the tank safely sitting on a table several feet away, full or degassed if you choose. There is no risk in accidentally discharging the gun because you are just left with the action and barrel.
-
You are right any pressure will make the parts hard to unscrew...and it should have been noticed in the first 1/8 th of a turn
Hindsight is 20/20
look at most of the old Crosman Mark I & II you find most have the knurls screwed up from channel locks. When the pistol started to shoot slow they wanted to change the bulb but the cap would not come off easy so they would use channel locks on them. If they would have read the manual they would know the cocking knobs can be pushed toward the valve at end of fill and degassed. CO2 pressures are alot less
Mike is very lucky this could have been MUCH worse!!!!!!!
-
yes the fill adapter was hard to unscrew.. the thought of pressure behind it didnt cross my mind and it should have. i thought the threads where damaged or it some gunk in the threads.. this was a highly stupid mistake the 2nd one i made that lead up to what happened.. i trusted the gauge, i got to comfy taking the rifle apart.. i was a stupid stupid man last night.. but i can own up and say this was my fault.. woke today wanting to shoot lol.. but ive got 3 holes to patch and a breech screw to get out so i can pull the valve and get to the bottem of why it didnt fire any air when i dry fired it..
today i still have some ringing in my right ear and my eye hurts about as bad as an eye hurts after it gets poked by a finger..hearing has returned to almost normal minus the ringing, vision is fine i havent noticed any loss of vision in my right eye..
tom- i am very very lucky even my dad kind of jumped on me for this when i told him about it today. i have decided tho to stick with a hand pump for a little while, tanks are a lot more dangerous then the airtube on the disco
but man i want to shoot today, any one know if the fill adapters can find local ? like what kind of place should i look for one at ? or would it be best to just order one from crosman
-
Fill nipples at the paintball outlet for the 4500 PSI tanks might be a fit if they clear the endcap recess.
here is an example
http://www.ninjapaintball.com/productDetail.asp_Q_catID_E_91_A_subCatID_E_78_A_productID_E_103# (http://www.ninjapaintball.com/productDetail.asp_Q_catID_E_91_A_subCatID_E_78_A_productID_E_103#)
you might need to bring the endcap and make sure it fits.
-
gonna grab my yellow pages and start calling paintball shops.. id love to finsih the tear down and get to shoot today
-
Mike just came on an read your's an other's posting's. Brother I'm glad you seem to be recovering O.K. an all is returning to normal. Take the advice the guy's have given ya to heart when doing "any" type of work that involve's high pressure's. Again Mike glad your O.K.!!!
-
Wow Mike, just came on and saw your post. Glad you're OK and trying to get back on the horse asap. Hope you're feeling better and getting better.
Glen
-
Is it possible that no air was coming out when you dry fired it because you were in complete valve lock? Since the gauge wasn't working could you have WAY over pumped it? Before removing the valve, you might just try pressurizing it a bit and see if air comes out when you dry fire. If it does, keep upping the pressure, until it's full, or air stops coming out.
Glad you're OK!
-
i was shooting the rifle the night before, then hung it up on my wall untill i got my parts in.. thats when i noticed the gauge said it was empty and wasnt shooting.. i did not over pump.. disco's are pumped to 2400psi all the time with the heavy hammer spring.. which i have done my self a few times and it shot just fine
-
Hey Mike,
Just noticed this scary thread. I am very glad you are recovering ok.
I am thinking the soft plastic material you had put in the tank for de-pinging slipped inside the tank and pluged the entrance to the air pressure gauge adapter. That gauge adapter just has a little (maybe 1/8") hole in it, and would be easy to block. That would have let all of the air be shot out of the valve and the gauge read empty, but the tank would still have full pressure in it. What makes that scenario even scarier is that if you had used the degassing tool at the back of the gun, no air would have come out when it pressed on the hammer. So you would have been "positive" the tank was empty, but it wouldn't have been.
Thanks for making us all be more safety conscious. We are playing with fire and need to respect it, because it doesn't care about us one bit.

Anyone ever work in a garage or (what used to be) a "fillin station"? Ever pop the QD coupler loose on the compressed air line and let e'r fly? And thats only 150-160 psi!
Powerful stuff compressed air and gases, glad Mike is up and at it and sound enough to blog with us.

thanks guys, im fine well kind.. my right eye is sore about as sore as getting punched in the eye 3 or 4 days ago. best way to describe it.. hearing is slowly coming back little by little.. got a appointment tuesday with a ear doc just to be sure nothing major was damaged and to compare a normal 27yrs hearing to mine to again check for damage..
lloyd, since ive been tearing down the disco ive been suspecting exactly what you said.. (great minds think alike..lol) the first deping i did the tube rolled back the way it was since i had rolled it opposite of how i was before cutting the slit down it.. figured it wanting to unroll would keep it forced in there.. a day or 2 later i heard it sliding around and promptly removed it and used the silicone tubing i went out and bought just for the deping.. larger and thicker tubing... im think a peice or 2 from the first peice of fuel tubing i used came off and plugged things up.. altho i can remember double checking i didnt have any shavings hanging off it before incerting it in the air tube...
i can honestly for as bad as this went down it couldnt have gone better for something going bad.. this was a mike made failure.. a little ashamed of that but hey i can own up to my mistakes..
now i need to figure out how to get the valve out of the airtube and the gauge port peice out of the airtube so i can clean them up and inspect them then rethread my breech bolt threads since i had to drill it out
ive been wantin to do some shooting so so bad today its not even funny... i called every single paintball shop and even sent 2 of the guys pictures of the fill adapter i needed and i cannot find on in austin at all. which not worthy...

Mike,
Check out the videos I recently posted in Shop Talk about .25 cal Disco Fever and you'll see how to take it apart.

thats amazing because every single paintball shop here is Detroit area carries them the fit both the 3000 and 4500 regged tanks to fill them. Paintball guys carry spares with them so when the valve fouls they swap it right out at the field and refill.
Maybe you talked to the wrong guy try the biggest field that has its own compressor and talk to the guy who runs it (the compressor) they usually know the most as the rest are just retail sales clerks....
I'll bet you are crawling thru the attic right now with a mag light in your teeth looking for it

Hopfully you'll recover and be fine. Good to post the accident, helps make us all more cautious.
I've gotten paranoid about pressure in the tube...although my "whoops" was not nearly as drastic. Hard to be 100% sure there is no pressure in the tube.
If there is a gauge that functions correctly, may still not read that last 200PSI. Normally will manually depress the fill nipple's inner rod..if it is truely empty, should be able to.
But even with all that...gauge reading zero, gun not even making a burp when dry fired, and the fill nipple stem being free to depress...will slowly open the end of the tube a fraction of a turn, and look for air. then if it freely truns, open it one full turn and listen for air.
And even after all that..will be sure to stand to the side and point that end cap at something non-valuable as I turn it out.
My whoops? air tube with no gauge..an experimental valve that wouldn't have let loose no matter how hard you hit it...and a fill probe so i couldn't do the fill-nipple-check. A little dryw all, a little spackling, a little paint, and a lot of griping by the wife.

Mike I'm glad your not hurt really bad. Will keep you in my prayers for a complete recovery. Rickey

Holy heck!!!.... Just got on to read this.... Glad you're OK for the most part Mike.... There is a lesson there for ALL of us....

Mike, I am glad to hear that you are not critically injured. I may have missed it stated earlier, but would like to say one thing first, in general to all here. At a minimum, Safety Glasses. Think about where correct PPE should be applied. I would advise any one reading that safety glasses are not just for the shooting aspect of this hobby/sport.
When I am at work I deal with N2 pressures on the order of 300 to 15,000psi on a regular basis. On occasion even higher for design qualification and certification. Volumes range from approx 20cc to several hundreds of sq/ft. I work in the subsea well head industry and it is part of the pressure integrity qualification testing set forth by API on many of the well head assemblies we manufacture. I have witnessed ALLOT of ugly things happen in the oil field over the last 20+ years to people and coworkers with compressed gas and pressurised hydraulics. In one instance, I litterally have seen an uncontrolled N2 pressure release from the bore of a sub sea well head tree assy, propell that 27,000 lb tree 18 feet straight up into the air. It happened 15 feet behind me. When another technician unlocked the tree from the test fixture there was still only about 5,000psi trapped in the bore (was 10,000psi test). The concussion knocked my hard hat off of my head. my ears rang for a day and a half. Also have seen flesh split open by considerably less N2 pressure venting from a unsecured pressure line. I could go on and on. Gas pressure is the only thing in my work place that really puts me on edge.
The point is, compressed gas is capable of storing and releasing incredibly large amounts of energy in a split second. Just like a machine it has no conscience, get too comfortable, lower your guard just once, allow complacency to set in..................in many cases, it just takes once. I have fallen victim to complacecy, and was lucky to come out alive.
Mike, you have my prayers for a rapid and full recovery. Happy Thanksgiving to all.

thank you again guys for the kind words.. i can say if i had ben wearing safety glasses my eye would not have ben injured i guess that was stupid mistake number 3..
i have found the cause of thefailed guage, it was in fact a peice of the original fuel tubing i used for the deping. im going to be checking around the house for a section of pvc i can use to remove the valve and guage port. i might end up having to order a new airtube unless any one has a disco airtube laying around.. when i drilled out the breech screw i damaged the threads airtube and im not sure if i have to drill the hole in the breech out a tad for the screw since once i rethread the airtube the hole will be slightly larger thus needing a slightly larger screw for the breech..
nah havent been in the attic looking for the fill adapter.. plus im sure its going some dry wall packed down into it since it did cut a perfectly round hole in the ceiling.. so im just playing it by ear and wont be ordering parts untill i get it completely taken apart and then put back together so i know exactly what i need.. if i miss one thing on the order to crosman it will add an extra week to wait..

here it is guys, peices of fuel tubing that ended up shredded and completely clogging the gaug port hole that pass through the gauge port

I would just live with the ping....none of my rifles are depinged
the ping really does not carry very far from the rifle but sounds loud to the shooter
try it stand back 10 ft and have somebody else shoot the rifle
which direction did you push everything out???
-
ya i am just going to leave it alone
also found a peice of tubing that had been sucked into the valve
ps... trying to install the valve is a pita to keep it going straight down the tube with out rotating and messing up the alignment of the screw holes

Went to some doc appointments today
3 cornial abrasions which are like really small paper cuts on the eye, hurts to blink when you have them.. that pain went away over the weekend.. I've had a few of them in past but never 3 at one time. Pain wasn't bad enough to complain about since I've had them before..
Now to the bad news 5% eye sight loss in my right eye and about 10% hearing loss in my right ear.. I can't really tell loss of either one, but I don't have to renew my drivers license for another 6yrs so no worries there with the eye sight test..
Called crosman about parts and got a total price of 56.05 shipped for a new fill adapter, breech screw, air tube and gauge.. thinking I might get a gauge else where that gives a bettet reading of pressure and I'm still not sure if the threads on the airtube for the breech screw are jacked up from having to drill out the threaded shaft of the breech screw because it was bent in the airtube after I removed the head of the breech screw..
Can't order parts untill the 3rd of next month and my bigcat has a bad seal so I'm unable to shoot any airguns untill maybe the 10th when the parts would be here or around that time after ordering...
-
hopefully your eyes and hearing will recover more with time. if you were in NC and closer i'd loan you something to shoot til you got your parts. ;D

Thanks man, I will be back shooting soon enough.. the doc's jaw dropped when I explained what happened... the fill adapter and end of the barrel was a foot or less from my face the stock between my knees to help steady...
I've turned the bass down on my amp in the stang and won't be using head phones for a few months.. I hope everything will eventually get back to normal but if not I can say the lesson from this accident will always be in my mind anytime I pick up a pcp rifle...
I'm starting to want a mrod again...lol.. gotta get back on the horse or I guess pump in this case
-
yep. i always want another gun. it's figuring how to get it that's the trick. ;D i'm sure time alone would cause such a decrease in vision and hearing too. ;D did they say if that was permanent loss or may get better still yet?
-
I was told to not hold my breath on the eye sight or hearing getting better.
-
mike i hope they are wrong and you do improve.

Mike i would be interested in your old air tube if you don't use it.
DON

Good attitude there brother.
Richard
sometimes you just gotta pull ur man panties up and keep on truckin
Glad you are OK and sticking it out. Thanks for sharing your story as most probably wouldn't.

i will let you know, odds are im going to replace it but ive been considering doing a co2 crosmods disco or maybe a just a scratch built co2 disco for use with open sights for those close in critters.. its all kind of up in the air, but if i dont use it to build another disco from scratch i will be sending you a pm.. but to be honest man crosman said the airtube was 18.16 prolly just better to order ur self a new one

"dang" mike, glad you are ok. I know it happened a bit ago, but I just read it now.
