simple questions guys, in a coaxial that uses a piston to seal do i need to put o rings on the outer edges of the piston (you know that part that comes in contact with the camber)? and how big should i make the equalization hole?

ps - holy crap theres spell check now sweet

No you dont HAVE to use O-rings but they would help. If you dont use o-rings then you dont need an equalization hole.

Wheres spell check?

when spell a word wrong it underlines it in red then you right click on the word to change its spelling it awesome!

what are you saying you can't spell? jkz

Yeah the prof answered it but O-rings do increase performance,im not sure how much but Im not sure if its worth it to make the o-ring grooves if you dont have a lathe


Where is the spell check?

well i have a lathe but its only a wood lathe, any simple way to make perfect groves with a wood lathe

on the spell check there isn't actually a button but when a word is spelled wrong its underlined (at least on my computer) and i can right click on that word to correct its spelling

Spudwiki, type o-rings into the search or go to piston valves and click on o-rings. It gives a whole overview on how to do 'em.

O-rings are an exelent addition to any piston cannon. For some reason I dont have spell check.

The forums don't have a spell check, it's called you have Fire Fox V2.

Many use the small gap from not having a o-ring seal, as the equalization point. The same reason why you don't need a lathe for a barrel sealing valve.

O-rings will make a big difference in performance so they are recomended. If you wood lathe has a self centering chuck then it will work (thank gort for that info).

Well I made o ring groves with a knife with my hot glue piston. It works well.
