Title: Brass barrel pivot washers
Post by: Treb37 on May 25, 2012, 12:15:51 PM
After something on the order of 10,000 rounds, the plastic barrel pivot washers on my Nitro Venom finally could take no more. The pivot bolt was as tight as I could get it and still had side play. I could cock then slap the barrel sideways and get it to hit left or right of POI. I picked up a pair of 5/16 brass washers at Lowes the other day thinking it was about time I did that. What an easy thing to do. Just used a dremmel sanding drum and removed a little from the outside edge then cleaned up the faces with 220 grit paper to give it some texture to hold moly paste and wear in. It was a little tighter fit to get them back into the receiver but nothing unreasonable. When first installed I think I may have over tightened the screw thinking it would need to be torqued to the max to get good results. It seems that much less pressure is now needed to keep things in line. After some minor scope adjustments, it seems to be grouping better than ever. I was concerned at first that it was not grouping as well as before but after 100+ shots it seems to have settled in.

10,000!  That's a lot of shootin'.  Thanks for the specs on what you used.  I'll look for some next trip to the hardware store.  Tom

Two brass washers from hardware store, nut and bolt that fits through the center of washers, electric drill, file and some sandpaper. Make sure the bolt is long enough to hold the washers about an inch away from the head of the drill chuck. With both washers on the bolt, screw the nut into place so the washers are locked down to the head of the nut. Put the other end of the bolt into the drill and lock it down. The take the file turn the drill on and take enough off the washers till they match the size of the old plastic one. If you want to make installing easier then hold the file at 45 angle to each side of the brass washer sandwich while the drill is turning. This will give you a nice tapered edge just like the plastic ones have. Use the sandpaper to take any sharp edges off as well as put a little roughness to old Molly. i would suggest some thing finer than 200 grit but that's up to the individual.

A,most exactly how I make mine! I put my belt sander upside down in a vice and turn it on, and use it in place of the file. Works great, and washers fit perfectly. The 45 degree bevel does help with installation.

I found brass washers at Home Depot for $0.98 per pack of up to 12.

http://www.homedepot.com/webapp/catalog/servlet/Search?storeId=10051&langId=-1&catalogId=10053&keyword=brass%20washers&Ns=None&Ntpr=1&Ntpc=1&selectedCatgry=SEARCH+ALL (http://www.homedepot.com/webapp/catalog/servlet/Search?storeId=10051&langId=-1&catalogId=10053&keyword=brass%20washers&Ns=None&Ntpr=1&Ntpc=1&selectedCatgry=SEARCH+ALL)

That is sure a lot cheaper than paying $8.50 for only 2 brass washers.

I don't mind a little extra work to save a few bucks.

i have done the home depot version of the barrel pivot washers and got  a set or two from airgun toys both worked well but i don't think the brass washers were of the same quality brass as the ones i got from air gun toys. the home made ones wore out quickly for some reason....

I went the homemade Lowes washers route, and found the brass washers wore too quickly despite polishing, drilling for lube retention etc. Ended up using Zinc.

Post by: CharlieDaTuna on May 29, 2012, 09:30:42 PM
For what it's worth, I will tell you guys something. Precision is everything. ;D ;D There is a huge difference and wear factor using a precision CNC machined and beveled brass washer and one made on the bench using a low quality metal whether brass, zinc or steel.  :o  Zinc or steel should never be used on most guns.

A machined washer will normally last forever. ;)  Hand carved don't usually hold up well, are not precise fitting and will not pull down or seat evenly on the yoke which in turn can have an impact on accuracy and wear and tear on the pivot bushing that the bolt itself rides in.  :( :'(

It is well worth paying a few dollars for quality for something that will last the life of your gun.  ;D ;D

Once u replace the plastic with brass and lub with moly the brass will last literally the life of the air gun. The idea behind the brass replacement washers was precision and a 0 tolerance fit on each side of the barrel/breech block fit into the action.

Breech/barrle block will never move from side to side again wihile pivot bolt is secure.

Gene
I went the homemade Lowes washers route, and found the brass washers wore too quickly despite polishing, drilling for lube retention etc. Ended up using Zinc.
Maybe Gene will comment on this, but I'd think it would be important to make sure that the mating surfaces are smoothed. That is, the inside faces of the front of the compression housing which press against the washers' outside faces. Brass against steel should hold up for a very long time if both surfaces are smooth. A few rough patches, though, would really rip up the softer brass in a hurry.
Keeping in mind that brass comes in a wide range of alloys and hardnesses, and that hardware store washers are likely to be towards the soft end of the scale.

Post by: huklbery on October 31, 2012, 11:02:45 PM
I used Oilite washers and turned down the OD, its overkill but now its done forever.  Like Gene and Charlie say machined properly, the washers will last a lifetime, sanding some brass ones to fit will work as good or better than the plastic so its all good.

Post by: Mikes Garage on November 01, 2012, 07:34:25 AM
Gene, I've used your pivot washers in the past, and I ended up sanding down the thickness quite a bit to make them fit my Crosman Storm.  They were quite a bit thicker than the plastic washers they replaced.  Is that to be expected?

Thanks,

Mike

I have installed Gene's washers in my NP and my XL. They fit perfect. They were a little tight getting in but once in, they could'nt have fit any better. I would be willing to bet that if you were to try to install new plastic ones that they would be tight going in also.

I measured the original plastic and Gene's washers thickness with a caliper.  I read 0.064"-0.065" for both.   I thought mine might have been spreading the U receiver tube too much, so did the measurement.

Sure, the new ones being tighter hold the barrel up off the "Alive Jam" where as the old ones allowed the barrel to sag or settle down on it.

The difference is Gene's washers fit perfectly, and tbe ones ive tried have zero slop.  They are exact with no modification, and you don't have to shop.   It only took a few days to get mine.  I love tuning my guns, and Iove the B19's- especially the Stoegers, but I don't have time to screw around.  I get my bushings from Gene, my triggers from Charlie, and my spring, seals, and lubes from ARH  because these are the best you can get for these guns.

Keep an eye on that screw.   My poi was slowly drifting today.  Thought the scope was F'ed.   Found that screw backed out and rubbing against stock.   Tightened back down, with more blue loctite, and will let cure longer.   I also put some lead pencil witness marks on it.

The brass bushings should fit tight.  The plastic ones ade easier to install because ghe plastic flexes, so it slips in easier.  With the nice tight brass ones the breech block should just barely slide in between the forks without too much force, that way the bolt doesn't need to be locked down super tight to create a nice and consistent lockup with no play in it

I ordered My Gas Ram Mod & brass washers from Gene on 11-09-2012

Item# Brass Washer , GRS-NP Kit: GRS-NP Bushing/Washers kit

I did not receive a e-mail reply as the items have shipped yet, but Gene may not send a shipped reply

Just a paypal reply that they were paid for.

I will probably receive them soon.

My Trail NP accuracy is all over the place, I want to install the items and put another 200 pellets down range with my Trail completely tuned.

I also ordered the Charlie Da Tuna Trigger at the same time, I should receive that soon too, I also ordered a New Seal for my Trail NP, and have the Moly60 grease ready to go, I am ready to do some debur clean & light polish

Let the modding begin.

Title: Re: Brass barrel pivot washers
Post by: westgl on November 13, 2012, 01:08:24 PM
No I haven't shot a gun with a GRT-III trigger, by C-da-Tuna, Mine will be the first.

Right now I have cleaned the Barrel Goo gone Initially, then again after 300 shots, the barrel was dirtier the second cleaning.

My trail at 40 yards is all over, still getting use to the breathing & hold, I am getting a 6"-8" group at that range, i can hit a 1 gallon milk jug, but would like it to get a little more accurate.

I am sure the trigger and the other parts and tune should greatly improve things
Title: Re: Brass barrel pivot washers
Post by: westgl on November 13, 2012, 08:26:26 PM
I received my Brass washers & spacer today, i also received a confirmation that my trigger is shipping today

Today was a good day as I shot a 1-1/2" dia. target at 45 yards and hit it 8 out of 10 times,

This gun may be settling in, and now I am going to take it down for a tune, hoping for better not worse, after tune/debur

I think my trail likes a different hold, a tighter artillery hold in front of the trigger with my thumb above barrel, with a firm grip, almost like clamping the action to the stock, could It be my grip is holding something tighter that may be loose that is causing the larger groups this also got rid of the extra movement of my barrel.

Barrel screws are tight, I may look at the barrel screws to see if they are too long and bottoming out and allowing the action to move very slightly in the stock, I may go to hardware store and get next size shorter screw for all three stock screws.

Has anyone steel/Brass shimmed between the stock and action, Ala Mosin nagant accuracy fix, this may make a firmer mount between action and stock and have minimal stock to action contact, it may also take up any looseness due to stock's screws being too long

I am thinking that I still may be pulling the gun a little maybe due to the stock trigger's long pull, i have been priming the trigger as far as possible, and holding breath at top of inhale, while gently squeezing the trigger and waiting for the follow through.

This has helped but I want better.

I am thinking the Planed Mods, complete clean, debur, & tune, should make this rifle a Much better shooter

I have noticed that some say their guns like to be held snug against the shoulder and loose under the forearm, right in front of the trigger guard. This is what mine likes. You should notice much improvement after the deburr and lube. While waiting for the trigger, send as much lead down the barrel as you can. This leading-in helps with the accuracy.
Title: Re: Brass barrel pivot washers
Post by: gene_sc on January 20, 2014, 11:12:13 AM
Yes... with the plastic washers you breech n barrel will move side to side. You will notice that you will have to start adjusting your scope left to right for correction. Up and down issues are a different matter. But side to side POI changes between cocking cycles with plastic washer will eventually be evident.

Accuracy should improve after installing the brass washers. Yes if I remember correctly Dave Easly has used steel shims between the stock and action. A real big issue is the wood stocks are soft wood. As we tighten the screws up we compress the wood. Then they loosen up again. It is not always the case where the screws back of but the wood keeps getting compressed. A synthetic stock in many cases is the cure...:) But I dont care for synthetic stock...:)

Yes if I remember correctly Dave Easly has used steel shims between the stock and action. A real big issue is the wood stocks are soft wood. As we tighten the screws up we compress the wood. Then they loosen up again. It is not always the case where the screws back of but the wood keeps getting compressed. A synthetic stock in many cases is the cure...:) But I dont care for synthetic stock...:)

I haven't had my action(s) out of the stock in several months but two ideas I've been kicking around for my next time in are:

1) Soaking the inside of the front and rear screw holes with thin CA glue (crazy glue). I used to do this on RC planes to strengthen balsa in key places.

2) Drilling out the holes to accept a nylon spacer to take the compression instead of the stock wood.

3) More NVD stocks. :D

Anyone have any thoughts on the first two?

I really did not get it. I check my PM's daily and I never got it. I need the Transaction Number and not the Receipt. Try sending another PM please.

I guess not all guns are made the same.  I have a Nitro Venom and there is absolutely NO pressure put on the wood by the pivot screw.  I must remove the action from the stock to access the pivot screw and remove the barrel to access the washers.

When reassembled the screw is completely tightened before the action is replaced in the stock.  You can't even adjust the screw when the stock is on the action.

For me, I would not drive a 30 mile round trip to Lowes or a 80 mile round trip to Home Depot when I could get precision made washers from such a great person and friend as Gene or other stuff that good folks make and sell on this great board.  Or even if Lowes or HP were closer.  The only thing that tees me off is getting me in this addiction to start with. ;D :-[

Hello gene_sc,
i wanted to ask if there is any possibility to ship this washer to belgium or you can give the exact dimensions? So i can let turning a guy from here these parts (or it reaches to give him the plastic washers?).
I have tried to prepare some m8 washers from here with sandpaper, but it is not precise enough.

Regards

Yann

No probleme Gene,
i got a pm from  Roadworthy where he explains a little bit of the method of mtbrew and some ideas from him.
Yann, the gun you have will probably determine which pivot washers you need.  For the B19 platform (most Crosman break barrels) you need a washer approximately 0.062" thick, or about 1.6mm.  From my reading the 8mm brass washer should fill the bill nicely and not even need the outer diameter reduced.  Since I'm in the US, I go for a 5/16" brass washer, or better yet a bronze bearing.  In the case of the bronze bearing I went with 3/8".  It's not critical.  The thickness will be correct but the outer diameter is too great.  I put a bolt through my washers, tighten a nut onto it, and chuck it into an electric drill.  While the drill is spinning I apply a file to the edge of the washers until they have been reduced in diameter sufficiently.  It seems as though the final outside diameter is about 0.68" or about 17 mm.  It must be small enough to fit within the recess in the barrel.  Put moly on the moving side and you're done.

If the screw tightens completely before you have adequate friction on the barrel you washers are too thin.  Over time they may thin out anyhow.  You may then shim them.  Mine are shimmed at the moment with washers I made from a Coke can.  The aluminum is about 0.004" or 0.1mm thick.  It may take a bit of force to work the barrel back between the forks.  Once in place all should be fine.  Good luck!!


I now get a coke can (on some sites in the internet they say it is +- 0,065 mm thick. I mesure my can, it is 0,1 mm.)
I got some M8 washers and they are 1,5 mm thick. The plastic washer are 1,7 mm thick.
The outside of standard m8 washers are 16 mm (plastic = 17,5mm), so say fit well in the barrel.
I now put 2 shims that i made from my Coke for each side and the m8 washer.
To made the shims from the coke can, i take a drill of 7,5 mm for the inner hole and then enlarge them with the Dremel 911 Aluminum Oxide Grinding Stone to 8,5 mm (original plastic washers have also a 8,5 inner hole).
For the outside i put the m8 washers on it and i plot it with a cutter. After that i cut it out with a scissors.

The result ist, that i now can shot a 10 cent piece at 20 yards. Happy with this solution. And no play in the barrel.

That looks good Yann, but you might want to try brass washers. The metal of the compression tube/receiver and of the breech block is quite soft and I would be concerned about the steel (?) washers you used wearing the metal of the gun.

I'm glad it shoots well for you!

I write another time with Roadworthy and he suggest like stickstoff, to use brass or bronze washers. Because at the moment i have steel washers... Tomorrow i will look to buy some brass washers.

Thx

Hello again  8),
 
buy today M8 brass washers, they are are slightly thinner 1,45 mm. I take now 3 shims for both sides. Works great, no play in the barrel... see how much shots it take until retightening or new brass washers.
