Here in Massachusetts (US), willing to do some machining (turning/milling), TIG welding, MIG welding, thermoplastic welding, electronics work, woodwork. Machining should be not critical. I can give quotes at tospurr@gmail.com. Am busy, as I'm a full time student (highschool freshman). Decent TIG welder--better than any other 15 year old I know. Reasonable pricing/times.

Got some Glock 18C rail mounts which turned out to be useless as they were made for non-blowback models we don't stock, a bit of milling and converted them to revolver rails :D

Yes, I am deeply ashamed that I fitted a suppressor to a revolver, but business is business...

Damn, that's sexy. I never really pictured a revolver with a red dot sight on it, but a suppressor has been a childhood dream of mine...........*Tear*

Cracking job.

Cheers :) there are very few revolvers where a suppressor would actually be practical though:

Of course there are some nifty little revolvers on both sides of the Atlantic that don't need suppressors:

I never got why nobody's ever tried putting the cilinder inside of the suppressor tube...

Technically that's what the PDSR-3 does: http://www.cqbservices.com/?page_id=179

You still need to open it to reload though. An "ingenious solution to a non-existent problem" sums it up pretty nicely.

I need 2 small things machined:

a relible piston with sealing face for my coaxial gun, it will be based in 1/2 inch type m copper pipe
also need something that can center the barrel inside the pipe body without obstructing airflow. The barrel will be normal hobby shop 6mm brass tubing.
I am in america, and have 10 dollars in my paypal account, let me know if that is enough

sagthegreat, could you put a diagram of the parts needed? I have 1.25 round aluminum and 1.5 round steel. I will not do O-rings however, unless I had the mating pipe in my shop. Got some sheet rubber in the shop too. So only time for me.

I suppose those parts would fit in an envelope, so that would be cheap shipping. Just guessing, but sounds like a 1-2 hour in the shop, 20 min run to the post office/ package it. I'd quote 20 as a high side cause I don't like feeling suckered when like most projects I under estimate the time involved.

I was thinking something light like derlin for the parts as a lighter piston travels faster

the piston is simple round derlin with rubber sealing face


the barrel centering thing is like this: http://imgur.com/ynNZEpY
but a a bit more open to allow more flow
