Re: Need opinions/advice on a bb gun design

Some more work done on the receiver, drilled the port from the bottom, and I am toying with the idea of it's plug being also a screw that's holding it to the stock. It would be hidden under the guard probably. https://c1.staticflickr.com/1/258/18760343278_64fb95fc2d_z.jpg pcp montaza2 by Goran P , o...

Re: Need opinions/advice on a bb gun design

I guess my 22x2 with car compressor would be quite OK then. Got my bandsaw back in the working order with some nice new bands, 6mm wide, supposed to cut even mild steel, but I don't suppose I'll try that ;) Looking around the shop and some pieces of cherry look suspiciously like a RB stock, we'll se...

Re: Need opinions/advice on a bb gun design

Overkill is not a problem :) 5.5 is cheap and readily available, and I would primarily use it for plinking. 10x2mm that I can get is supposed to be ID6mm, but it never is, it's closer to 5 really, so I enlarge it a bit. and its just right for 5,5mm. These tubes are rated to 9bar I think, ~130+ psi. ...

Re: Need opinions/advice on a bb gun design

Brian, I drew up something based on your concept, and tried to place it in the form of one of my favourite single shots, Remington Rolling block. Billie Dixon model, 30' barrel, completely to scale, just the barrel is thinner than the original, which is 30mm diameter. Mine is 22mm, and should be cou...

Re: Need opinions/advice on a bb gun design

Finally finishing the pcp. The barrel is threaded and epoxied in, and the reservoire is finally sealed. I will file it flush today and epoxy coat the surface. The action still needs some minor work, mostly due to my fingers being unable to place the 5.5mm pellet into the barrel from the first try :)...

Re: True Bolt Action 6mm Cannon

Great work! The sound it makes when operating the bolt is just perfect! Regarding the wood finish, don't use just lineseed oil, it's commonly called that, but what you want is a mix - equal parts lineseed oil, turpentine (oil thinner is cheaper and equally good solution) and oil varnish. In my expir...

Re: Need opinions/advice on a bb gun design

Thanks a lot Brian, both for the drawing and the kind words!

It's actually simpler than I thought, great! :) I'm already thinking about the tubes that I already have at the shop,and the ways to hit the pilot... Some drawings are to follow!

Re: Need opinions/advice on a bb gun design

Thanks a lot! It's not hard really, nor that time consuming. Start with a nice piece of wood, sand the outline nicely when you cut the shape out, use the squareness of the blank to route the inleting using the routers rail guide, and shape all the round parts of the stock one facette at a time with ...

Re: Need opinions/advice on a bb gun design

Found a few pics of the making of the stock...it was first a springer, but the finished rifle was to hard to cock without a lever, so I reused the still-in-the-rough stock for a PCP with really small modifications. The tube and the piston are still around, waiting for a better idea ... https://c1.st...

Re: Need opinions/advice on a bb gun design

Hvala puno :) Thanks a lot Brian! I've been looking at your rifles for a few weeks now, hoping to make something simillar at some point. What I don't understand is how do you refill a coaxial valve for multiple shots? Is there another valve somewhere that I can't see that when opened, refils the coa...

Re: Need opinions/advice on a bb gun design

Thanks a lot! When you start the carve, just ask me if you need any details on what I did here. I might have a few pics of the process... Regarding the tools, nothing fancy really, I've cut the outline with a jigsaw, and the inleting was routed first, fine tuned with chisels. Outside was carved with...

Re: Need opinions/advice on a bb gun design

Another revision - realised that the trigger is upside down :oops: https://c2.staticflickr.com/8/7777/17969378340_c6215d6702_z.jpg Broke the piston/cylinder parts down, going shopping soon, so I need a shopping list. I will solder the parts together and try at least, to do the lathe work on the dril...

Re: 6mm Compact Copper Air Gun

I found 2 small machine shops 5 mins from my place willing to do lathe work :) I'll probably get my springer piston and cylinder from them soon, so if you do come across the plans, it would be great to get a copy :)

Thanks!
