Whether you follow through with it or not, what airgun related project did you plan out in your head today?
-
This should get interesting ;) I will have time to think about this while in a tree stand :)
-
"Following through" being the key. I still need to chrony the Avenger. :o Plus I still have tools and whatnot scattered throughout the shop from the recent house projects.
I just get sidetracked so easily.
-
Well I decided it was a good idea to bring my Talon SS up in the treestand with me when the squirrels would not stop chattering ;)
-
Have the thought to take the k98 and d48 to longer range and dabble in the following variables: ftt head sizes. Only thing missing is the range: already ordered the 4.51s to complement the 4.50s and 4.52s I have on hand.
I have a .25 spacer in the piston of the K98 as well as two of the same spring. Thinking of trying with and without spacer with both springs. Another voice in my head says, "it's shooting just a hair below 890 fps with a tight ES: don't mess with it!" That voice usually loses out when my behavior is the measure of winning or losing. We'll see. The match gate ending today might push me towards manifesting the latter idea this time.
-
I just ordered another rifle for the collection. This one is a PCP. So now I'm playing the mental musical scopes game. Hmm. . . . . One of the 1400's needs a reseal. I could kipe the whole scope and mount for the new Beeman. I might use the monster 4-16X40 CenterPointe that's sitting on the bench since I moved the Leapers to the mod 125. Or take the Optima 4-9X30 from the 2100 and replace it with one of the Ruger 4X's that never seem to die. 4X is plenty for the 2100 and the Optima will serve on top of the Beeman until I can get something better. :D
-
I came up with the idea of trying to make the daisy 499 of BB pistols.
To take a daisy no.177 " target special " and actually make it accurate enough to punch paper at 10'.
As is they do about 3" groups at that distance.
My thought is to get a parts gun or a lone shot tube, then find away to remove the muzzle end and thread / feed assembly attaching them to a section of model 499 barrel.
I'd be happy if I could shrink the groups down to 1", but I'd be ecstatic if I could end up with a true target BB pistol ( except for the trigger anyways )
Being able to use the standard gravity feed would be great, but I'd be okay having to muzzle load it.

Aside from the 4-16X40 CP being on the large / heavy side, I would go with that. I have a couple from way back, always thought them better than the Optima.

It's gonna depend on weight. The CP is just too heavy. I'm considering a Hawke Vantage.
-
I like the hawke 2-7 vantages. The milldots aren't the best design, but they're there.
I'm surprised you're not going for the winchester 2-7. It's got no dots and the glass isn't quite as good, but I like it just as much as my hawkes.
Sometimes dvor has crazy sales on the vantages. I've gotten them for under $100 even with shipping.

That's another option I mentioned. Pulling the Winchester 2-7 scope off my 2nd model 1400 since it's a wall hanger right now. It's only gotta last until Christmas. I'm definitely buying a night vision scope for this gun. That was my rational for purchasing a .25 PCP. I want to go night pesting!
-
Since TenX asked about night vision I have been having vision of getting another one I have the thermal covered but it does not do video. The day night ones I am considering do video. ???

Aw $hTt, it's on!

I took an XS-60C bolt action co2 rifle and added a mag and turned it into a crude pump shotgun type action, actually works quite well......
-
Interesting.
Good to see you Mike.

I designed and 3d printed a square that fits in my daisy 901 pellet chamber, so I can load in the pellets without it being, which at times it can be.

I'm having a hard time visualizing the pump feature but you got my vote for the magazine. I love mine BTW. Like a death ray for rodents!

Thinking about taking apart the diana ems loa i was planning to loan to a friend, deburring, changing the piston seal, maybe changing the spring, and getting it up to full power again. I haven't mailed it yet and it was a surprise anyway. Might as well tinker it into great shape now that the k98 and d48 are in a good place for now. Craving a springer project maybe. Bravo's thread on his ems loa (we both scored them on a crazy deal a couple years ago) inspired the idea. The ems is strange with it's lack of a piston stem and ample opportunity to knick the piston seal on reassembly. It buzzes a bit so in addition to the spring, I gotta be mindful of the tophat with stem design.
-
On top of thinking about my daisy no.177 project I'm also contemplating maybe swapping stocks between my 140 and the 1400 I just bought.
It depends if there's actually a difference in cheek weld, but I figure that since the 2nd variant 1400 has a dovetail that I can mount a peep sight to I might prefer a combed stock.
-
The Beeman Raider proved to be particular about what scope it likes but I finally got it sorted out. Now I'm watching videos about the Bstaley O-ring mod to control hammer bounce. I have a rough idea based on another members description of how it ought to work on the Beeman. Right now I've reached a sweet spot through a combination of a 2,500 PSI starting fill, a 20.06gr pellet and some hammer spring adjustment. Going much above 2,500 PSI doesn't help as the hammer bounce eats into the efficiency and a heavier pellet aggravates it. I'm hoping the O-ring mod will let me pump the gun up to 3,000 PSI, adjust the hammer spring for more power, and go up to a heavier pellet. Hoping for a longer, flatter, shot string with heavy pellets and no hammer bounce. Time to go shoot the gun down and de-gas it
-
Trying to come up with a viable shroud concept for a Huben GK1. Kind of hard work for me, having never seen a lot of pictures of good working shrouds. Idea is to pull off the aluminum "shroud" which has no sound deadening, and replace it with a CF tube and baffles. Picture of my current noodling in the PCP gate. The idea is still half baked, but slowly making progress. CAD work is not my forte. But it's darned helpful to see how things go together, and even more useful to generate drawings to make parts.
-
O'kay. Train of thought here. I watched a flock of Starlings flying over today and thought about what would happen if they hit a drone (bird strike). Then I thought about mounting a full auto BB gun on a drone with a HD camera and going Starling hunting.
If you are familiar with what they are doing in Ukraine right now you will realize that this Fisher Price stuff.
-
Sounds to me that most folks prefer the current hi-tech options for their tinkering.
I'm just the opposite as I like simplifying my "toys", such as putting AR15-A2 irons on my TalonSS,
Falls right to my eye on that straight "comb" tank/stock. Much better than the AirForce open sights.
Little bit of adapter work to do yet on the front sight dovetail-weaver riser.
I like the lighter weight of the rifle without a scope. No lenses to fog, break etc. No batteries to go dead, etc, etc, etc.
Most of my shooting is on the south side of the house, the sunny side of course. Red dot not visible most of the day.
But my red dot cowitness's with the irons for the times I can use it.
That's my walk-around favorite. 50 yd and under, offhand.
For loong range ground squirrels I have my FX Maverick Compact 25 cal., benched of course...
I'm rolling over my lifes odometer, in three weeks, to 79.
P.D. has me by the "how-you-sayits" so my hunting options are limited to bench shooting, in the shade.
So to complete the picture, I enjoy driving a standard transmission car rather than an automatic, except in heavy stop-and-go traffic.
Also prefer working from the terminal on computers, except browsing web and pictures.
Prefer Linux to Windoze which I quit 21 years ago.

President Kelly of Allegheny County Labor Council energetically stated when Amazon moved in that the day a drone delivers a package to his door (thereby displacing a postal worker) is the day he blows a drone out of the (expletive) sky.
I don't know much about drones, but if they can deliver Amazon packages, an electric bb gun might be DIYable. What might putting that together look like?

I gave my buddy my 2240 with a buckrail moderator to learn to shoot while sitting out back by the fire. I also gave him one pf those pinwheel metal targets with 8 or so arms. We call it Clocktopuss. He let the cart get too low and shot the moderator off, leaving him with no front sight.
He now claims he is shooting better without sights. The above post about going lower tech reminded me of my buddy getting better shooting sightless... at least supposedly [chuckling].

An Umarex T4E HDS double barrel .68 CO2 "sawed off shotgun" shooting a wad of BB's encased in wax is still rolling around in my head.
I held one at Kalamazoo a couple years back and shoulda bought it then.

I'm thinking the Umarex/Legends M712 attached to a quadcopter drone with a paintball style gravty fed hopper full of BBs tethered to a paint ball tank full of HPA.
Battle climb to 100 feet to intercept a flock of starlings! Fly the curve of pursuit to bring you into a zero deflection six o'clock attack position! Pick your target. Dive into the flock, close to ten feet and open fire! Maintain your closing speed and break upwards to regain your altitude for another pass.
Keep your eye on YouTube. Someone is going to do it eventually.

Give it a couple years and you'll be able to push "play" on your personal robot to build one for you. :-\

Hey I shot a chipper in the head DRT with my 2240 before I mounted sights, I think it shot better then too LOL

And now for something completely different, I am making changes in my gun room and need to stack guns neatly, this looks like my best option on the cheap, I'm thinking pallet wood ??? hardest part is reclaiming the pallet wood, I do have one of them fancy pallet board removal tools too ;)

Back on topic ;D
I was given Nicks old Chaser stock that was missing the rubber butpad, and discovered it fit my pp02 4.45mm .177 cal. pistol. Hmm it did need a 1/4 inch shaved off to nest in the pp02's grip.
Now it has been laying around in the shop at work,"still holding CO2 for months". and I kept forgetting to bring it home to scope it and see what it can do.

Well it did this after sight in the holes up and right are from initial zeroing shots, then I let the Ruger .177 hollow points fly. ;D 10meters sotra rested. :o Next time I will try off a bag.

didn't like the lack of gauge for the older Airforce bottles. So I made one for filling the bottle from my tanks.

Instead of using pumpers to shoot 16gr to 21gr pellets at shorter range, I was thinking of a pcp shooting 30gr to 40gr+ projectiles at shorter range (with similar velocities)... Toss on a red dot or "See All" sight to the Umarex Origin I've had collecting dust in the safe and it should be good to go.
Alternatively, taking that Origin add a 20MOA compensation rail (use single shot tray after), no limit rings, free float the barrel and practice at further distances for NUAH... When the weather allows. Also need a bigger tank. Thought about somehow mounting twin 700cc bottles but one big remote air supply is more practical.

I've thought to make a stubby 13xx gun, just not sure this would work... Or would be safe... Basically get rid of the pump assembly, cut the pump tube down so the valve cone is exposed or have easy access to. Drill & tap the valve end/cone to fit a quick fill fitting, fill via hand pump (1100-ish psi). Chop barrel to desired length, add barrel band, steel breech and sights...

Should be ok to 2000 no ??? think maximus ...

This isn't a new idea. Been doing this several years. Mounting Pistol scopes on springer air rifles scout style. I use barrel accessory mounts. One or three picatinny 5 slot rails on the barrel slid back to the barrel block. An off-set one piece scope mount, some see-thru if I want to be able to use the open sights. Because of the length of an air rifle receiver pistol scopes like BSA 2-7x28 edge pistol scopes work better than scout scopes because they have longer eye relief. I have them on break barrel, under lever and side lever guns.
I did this first with my Beeman RS2 dual cal. so I wouldn't have to re-zero when I changed barrels. Later with old guns like some of my old Chinese guns or my BSF c60 because they didn't have scope rails or 11mm scope grooves I mounted pistol scopes on the barrel. They work good.

Will do. It'll probably be bit before complete.
Have to find out if drilling & tapping the nose cone of the valve directly for a fill nipple is going to be an issue or if I need to come up with something different... Everything else seems straight forward.

With the weather being what it is, my shooting has been in the Man Cave. I'm growing weary of group shooting. So I'm working on a backstop/ trap to put my
spinners in. Need to do a hardware run for some short drywall screws. I have everything else setting together waiting for assembly. I did this shooting last
winter while healing up from shoulder replacement but I thought I could come up with something better.

I hear ya, loud and strong. It's only been 8 days since I shot outdoors and winter has a long ways to go. I'm thinking of what to put on the floor in front to catch bouncebacks from the Rockin' Rat. Spinners can move in more than one axis when hit at an angle, so that seems riskier to me.
For the low-powered shooting I do inside, multiple layers of corrugated cardboard (6 or 7) lining the inside back of a large box suffice in that direction.

I put the Baker Airgun Scope Mount back on the Crosman 392PA,
put the Optima 3-12x50AO back on,
and I put new elastic strings on the scope covers 8)
and, ended up with the Bushnell red dot on the 2240 carbine.
Just sighted them both in. ;D ;D ;D

Airgunaut, Finished the spinner/pellet trap yesterday early in the morning. Gave it a couple shots then checked the floor in front of it for spatter. Not bad, then set a sheet of paper & a couple pieces of batting from an old seat cushion down in front of the container to see how much spatter comes out of the containment.
This seems to keep most of the debris in as most spatter from pellets go straight down. So did a bit of plinkin' a bit ago, it's just to dang cold for outdoor shooting !

How about a 1377/22 XL and a C362XL.
Ditch the 1377 tube diameter, and use the same diameter airtube as a 2240.. that would create abit more air with each pump.. but how you or I would build such a thing idk.,Crosman would have to make new airtubes and pistons seals and such to build such a thing.
Just a thought

Yes, I think it was him, or something like an explanation as to why it’s not feasible 🤔

Been thinking of a pumper for possible ghog duty. I've been using the S510 and have other ag's that are capable, but I've been on a pumper kick lately. I have two Benji 392's, probably capable... But I need an excuse to get a C362 and hot rod it a little :P
Read something about hogging out the valve some with a 25/64 bit, have some ice maker tubing already and go 11/64 with the barrel port and valve exhaust... Might try hogging out a 760 valve first to see how it goes.
Still have a project or two to wrap up first.

Thanks... the Rocker 1 moderator is so effective, it is hard to tell how truly powerful it is without running it across my chrony!
The barrel is a modified NOS Sterling .20 and its T.P. passage is the limiting factor for all the "Go-fast" goodies it has.
I am going to have to wait for warm weather to actually test any improvements.

He's made 2 I think. Great build threads to read if you can find them.

Crosman would have to make new airtubes and pistons seals and such to build such a thing.
Just a thought

A 2260 tube might work. Or a disco or maximus tube if you can find one. Use a valve from the mk-177. Might have to fab a custom piston. Maybe a Benji 392 lever and link assy.?

Here's one to think about.
A hollow pressure chamber containing a small quantity of denatured hydrogen peroxide and a tiny, isolated pellet of a solid catalyst. When the catalyst and the HP are brought together a reaction occurs. The chief product of the reaction is high temperature steam and carbon dioxide. Steam is naturally expansive. You could use this to power a PCP. Because of the temperatures involved there are firearm like challenges to be overcome. How to contain and direct the steam I leave to someone else.
I was trying to think up uses for a small Walther cycle engine and this occurred to me.
