Hello, Could you tell me how much your bolt weights? Also, do you know if it’s true that you need at least a 0.4lbs(181g) bolt to safely fire a .22LR open/bolt gun?
I see from the comments, that you bought the barrel, but i'am curious about what these barrel blanks are made of, i mean wich kind of steel classification.
It somehow turns out, that here in Germany you cant find ANY detailed information about that. Do you know where i could turn to, to get these informations?
@JaasterMareel The barrel was advertised as 4140 steel, and (although I was skeptical at first) the machining and parkerizing qualities seemed to bear that out. Usually .22 rimfire barrels would be made from low carbon steel... probably a free-machining type. I don't know any good source of information, but I think most centerfire barrels would be made of something like 4130 or 4140 at about RC 30 or so hardness.
I'am going to look this up further, but this is at least something to start with.
In German Wikipedia and other sites they only tell you, that modern Gun-Barrels are made out of carbon steel... wich is not of an information, since there are thousands of carbon steel kinds out there.
@JaasterMareel in germany you can get use plumbing pipe for barrels (you don't need a WBK to get it) but it's unrifled. the website "thehomegunsmith,com" has a chart with the necessary meassures

@hairydevil7 Thanks. The barrel blank I bought off eBay just before they banned gun barrels. I'd check Numrich/Gun Parts Corporation and Green Mountain Rifle Barrels for economical barrel blanks now.
Nice, im too lazy to make a "real" pistol(and i dont have a lathe), so i used a piece of steel pipe and a cap on the end with a hole for the fuze attatched to a piece of wood, tin foil balls for a projectile only, i dont want it to blow up
@ChaotixMachine I used a "mini'mill" I bought from Harbor Freight for about $500, plus a small 5 inch metal lathe and a belt sander. I made all the parts myself, except a factory barrel blank and a few screws.
@randallcaster Thanks. But the grips are actually a bit embarrassing to me... I was careful to line up the actual "grain" of the wood lengthwise on the grips, but somehow did not think about the "curl" pattern until I had them half made already. Therefore the curl pattern is totally mismatched in its angle from side to side on the gun. Oh, well... I made 2 guns at the same time, and all the best parts went into the other gun with walnut grips anyway. This one is a collection of 2nd best parts.
No man!! Nothing to be ashamed of, that's a very minor thing, and you're to hard on yourself.
I've made a firearm, and believe yours to look better than mine. Just the chose of using a time honored classic wood, from=instruments to guns- is something. That's a fine looking weapon from a design standpoint, period. You should, and I'm sure you are (but humble), so there!
@N2thedrink Another reason for building it was technical curiousity. Again, "everybody" said an open bolt could not be accurate. Well I wanted to see how accurate one could be if the bolt mass was minimized to the limit while making the overall gun weight as high as reasonably practical. The answer is it is not super-duper accurate, but this scoped one can hit a soda can about every time at 50 yards if there is no wind and I shoot off a bench with sandbags.
@N2thedrink On one level I can't understand your question... Why do anything not absolutely vital for your life? But on the other hand, I do have answers to your question as well. One reason I built this and posted it on the internet was because so many people told me it was illegal to do so and I knew it was not. Congress never passed a law against open-bolt firearms per se and I'm here to claim, and proclaim, this right to make one. It is a political statement.
@MrSexyGeek No, it's not that type of thing that absolutely anybody could put together. I'm a professional machinist, so I could apply more skills to the project. Using small hobby type benchtop machine tools, I machined all the parts from scratch. The upper and lower receivers are low-carbon steel, the bolt and trigger parts are O-1 tool steel and heat treated. The barrel I made from a blank I bought on Ebay just before they banned gun barrels there.
@MrSexyGeek It fires .22 Short only. I could just as easily made it for .22 Long Rifle, but the less powerful Short cartridge keeps my bolt weight down for faster locktime and less pre-ignition jump of the gun. Also I felt the Short cartridge minimizes any danger of legal trouble where the gubbermint guys claim it is a machine gun just because it fires from an open bolt.
@humafrag I bought a barrel blank that was rifled internally, and of course I bought the scope and mounting rings. Everything else I made myself. Except maybe a couple screws and pins, or coil springs I bought as pre-coiled stock.
@omniwelder I'd say this one with the scope on it will shoot 1.5 inch groups at 25 yards, or hit a standard size soup can nearly every time at 50 yards, shooting off a bench. Because of the jump of the open-bolt firing mechanism, it is very sensitive to variations in grip or support... if it is zeroed for shooting off a bench with a sandbag, it won't be zeroed for standing Weaver stance type shooting.
is there an ejector for the shells and how does it blow the bolt back is there like a diconector on the bolt for the recoil to kick the bolt back? your system is very unique my friend.
@goodgod09 There is an ejector, which is just the tip of the recoil spring guide rod which pokes through the bolt face when the bolt is fully to the rear. There is no extractor, though. The pressure of the powder burning kicks the empty case back, and the bolt with it. There is a disconnector so the sear catches the bolt open again every time, though you're still holding the trigger back.
Despite the simple design I do like the fit and finish on this,all you need to do now is make a mag well and mag and you'll have yourself a blowback open bolt machine pistol.
I would have designed it much differently from the start if I had wanted to make a machine pistol, but unfortunately it is nearly impossible to do that legally here unless you have a government contract in hand before you begin.
that is the coolest gun. you did a really good job. so good it looks like you bought it. you got some great machining skills! nice work! i assume the barrel is rifled rite? you should start a company making target guns. this thing would sell! hell i'd buy it!
My workshop consists mainly of a $500 Harbor Freight "mini-mill" that I braced up more rigid, a toy-like Emco 5x14 lathe, a $200 Harbor Freight metal-cutting bandsaw, and a Craftsman 6x48 belt sander. Plus a small heat-treatment oven.
Yes, at least to my own satisfaction. The pull with the original sear and bolt was probably over 30 pounds. After re-making those parts I got it down to maybe 8 or 9 pounds. I don't obsess over super light triggers, so it's OK for me.
Thanks. No real prints, just a pencil sketch of the layout on graph paper. The smaller details I made up as I went along. The barrel has a reduced shank that is pressed in and cross-pinned.
No CNC involved. Mainly I used a small "mini-mill" I ordered from Harbor Freight (which I braced up to perform better) plus a very crappy little Emco "Compact 5" hobby lathe. It was all manual machining. Also used a belt sander and some woodworking machines.
its awsome i also build my own rifle but in a more simple way i wouldnt recommand your pistol for room cleaning from terrorists because its single shot but its really nice build
I love the name haha
