Ok thanks i might see how epoxy pistons go. Also, on the how to, do you put the bolt and washer in before or after it has dried.
EDIT:

i just got the piston to actuate pretty fast after a bit of fiddling with lube and different pistons and man this thing is loud

Now lets see what the new-impoved piston can do.
I'm guessing lots of power

and noise.

I'm thinking that's a pretty good guess.
Congrats on getting it sorted. It's a real looker with that stock too.
Now...Go forth...and bring ye back the damage pics.

Double post!

The steel ball bearings came today (9.5mm) and at low pressures (50psi) they have alot of kick but unfortunatly ive got a leak so i need to fix that. PTFE tape dosen't seem to work that well anyone got any other ideas?

I've had good results with araldite at up to 850 psi, seals well but if you need to take it apart you can still force it to open.

Yes, you can turn PVC on a wood lathe. You would be better off having a clamped cutting tool, though, rather than a hand held tool. A clamp on a screw feed would be best. PVC doesn't mind a little higher turning speed but using a little oil while cutting will still help keep the cutting tool cool enough so that you are cutting and not melting and cutting.
I turn PVC on a mini lathe and use cheap steel for cutting tools rather than the HSS I use on aluminum and other metals. You can harden that cheap steel with a good heating and quick quenching for your purposes.
EDIT: Nylon is also do-able, easily.
