Does the piston have to be heavy or light or doesn't matter?

what can i do if my piston is slightly "centimeters'' smaller than my tee?

where does the small equalization hole go? do i drill a small hole through the piston or what?

Can the piston be metal?

already went to wiki. i just really want to make sure.THANK YOU'S.

Does the piston have to be heavy or light or doesn't matter? lighter = faster opening times.

what can i do if my piston is slightly "centimeters'' smaller than my tee?
adding O rings?there must be a O ring for the adequate size, the inner diameter of the O ring should be the same as the outer diameter as the piston ANd the outer diameter should be the same as the tee or whereever you are going to put it.
where does the small equalization hole go? do i drill a small hole through the piston or what? if you are using O rings, yes, sometimes the air passes trough the sides of the piston.

Can the piston be metal? Dont think so....Too heavy.



If u want u can make a Hot glue piston, very reliable and seals great!

just take a piece of pipe the same diameter as the one into you piston's housing (for example: if you are using 2'' tee use a piece of 2'' tubing) and put it on a clean a smooth surface and then add some non-stick spray into the pipe so the hot glue gets easy to get out of there. pour the hot melted glue into the pipe make sure the piston is like 2" high wait till it cools.
after it cools just push it out of the pipe, glue a neoprene/rubber sealing face onto it, test fit ( 8) it will...) lubricate and less but not leasst

ENJOY

If your piston is too slightly too small for your housing, just wrap it in duct tape and lube it. And yes you can make a metal piston but not a solid one...think about how you can make a metal piston "smaller" and therefore lighter but still be able to seal.

1) A lighter piston gives faster actuation times and is less likely to break the valve when it actuates.
2) For a simple solution, you can just wrap the piston in a few layers of duct tape; its ghetto, but works well.
3) If you are not using o-rings, you will not need an equalization hole.
4) Yes you can, if built properly.

If it's a hot glue piston do i still need to add an o-rings/rubber disc/bolt+nut & a washer?

Also if i use a hot glue piston do i still need to put a equalization hole or not if yes where should i put the hole?

Can a coaxle gun, "piston'' be a repeater?how is it made? thanxs!!!

how much psi/pressure can a hot glue piston handle?

sorry im just reuping.

no you dont need O rings, i can handle at least 135 psi, i know it can go higher, but thats as high as ive gone to. this is how you make a repeater.

with a hot glue piston do you still need a equalization hole?

Ya... you would need to make it tiny so that you can exhaust the pilot faster it bleeds pressure from the chamber.
