Cheers that looks like a great project

@Wyz2285
No don't have the mill attachment. I've seen its possible to do some milling by mounting a vice with vertical travel to the cross slide then putting the milling cutters into the lathe chuck?

anyone got advice on that?

Recently gained access to one of these: http://www.mini-lathe.com/C6_lathe/C6/c6.htm#Introduction (04/18/07) I have done a lot of basic work on lathes in school metal work but understand i have a lot to learn. Anyone suggest any basic projects? or got any simple designs for hammer valves etc. to loo...

If you used a hammer valve to pilot a QEV would it empty the entire chamber of air, or would it be possible to set up so the piston re seats itself fast enough so it only empties part of it?

havn't had any problems with the lathe so far. i havnt been able to get a great finish on steel yet but im sure that will be down to the quality of my tools

cheers :D yeh i've been practising on some aluminium and steel.
is ali strong enough for airgunning purposes? like valve bodies and things. I have heard its strength can be limiting for some applications... and have found it doesn't produce the neatest threads compared to steel. but steel rusts :?

Yeah i thought about this. Might even consider casting my own just for the exercise of it.

0.22" is not too easy, however you can "roll down" a 0.22 pellet to fit in a 5mm barrel, or tap it out like so to fit in a 6mm barrel: http://www.spudfiles.com/forums/adapting-0-22-airgun-pellets-for-airsoft-barrels-t7178.html oh clever. yeh ill look at 6mm then so it can be adapted to airsoft i gu...

cheers for the advice. Does anybody know where pipe/tubing with ID 0.22 (5.59mm) can be sourced? i have had a look online but haven't been able to find anything suitable. .177 is easy because some a standard gas tubing size is 4.5mm ID Otherwise i may need to look at another ammunition than air rifl...

Ahah congrats on 20,000 Okay if thats the case i think ill still go ahead with my plan unregulated at some point because i like the action they have. I'll look into the self contained cartridges because that would be sweet if i could somehow make them about the size of a 12gauge shotgun shell. Also ...

I would say it's actually easier than trying to make a PCP if you have machining macilities. Okay i might look into that further Not that regulator. I tried one, didn't work well at all, even ruined its own gauge. Petitlu on this forum had similar experiences with the same model. Haha okay cheers i...

have you thought of air cartridges? Guaranteed consistent shots, can be taken to high pressure and if you have a lathe making a batch of 10 is fairly easy work. Have a look at this , still a simple hammer valve ;) Yeah I am keen to make self contained cartridges but I thought it would be a more dif...

If you're concerned with long range accuracy, 80 psi in a small bore isn't really going to cut it. A ninja paintball tank regulator can be adjusted down to 450 psi which is within a good range for small calibres. Remember most airguns work in the 2000-3000 psi range, if you want to compete with low...

Internal Regulator for hammer valve pcp

Hey everyone i'm getting a lathe soon and i've been looking at designing a bolt action hammer-valve pcp to machine on it (i've had some experience with metal lathes). One of the main areas i would like to address is accuracy (perhaps over some distance). All my guns so far have been qev's and i have...
