1" Piston

Unread postAuthor: n-strike » Sun Jun 15, 2008 10:42 pm

Hello, I want to make my first piston, but I want to make it in a 1" tee...would that be too small or would there be a piston small enough to fit, AND actually work inside the tee? And I know this is like...my third topic in a couple of days, but this time I searched for 1" pistons and I couldn't find anything. Thanks in advance!

If JSR can make a piston smaller than a pen diameter, then you can make a 1 inch piston.

just make sure the barrel it is sealing on is smaller then the dia of the piston.

Why couldn't you make a piston smaller then 1"?

Obviously you didn't search very well, check the pneumatic cannon showcase.

would there be a piston small enough to fit

Well you do realise you have to make a piston right?

Then why did you ask 'would there be a piston small enough to fit'?

Which makes no sense if you know what you are doing. Judging by this topic, and a bunch of your other ones, you still have quite a bit to learn.


I suggest you lock yourself away in the Pneumatic Cannon Showcase section for a few days and don't come out till you understand how to build a piston, because all these topics by you are getting on the verge of ridiculousness.

That's how I learnt pistons, so I recommend you do it too. There's gonna be a time when people are going to get sick of your incoherent questions.

That's the beauty about pistons, you can use ANYTHING.


There is no 'set' piston, you can make a piston from anything you want. Though for 1" pistons wooden dowling works well, you'll have to find out what size though, just go to the hardware store with a piece of 1" pipe.

If it's too big, just sand it down.

Just FYI, I've made 1 1" piston in PVC housing and am working on another in a galvanized steel nipple. They each use the washer on a bolt design, and the first one at least works well enough to be piloted easily by a blowgun. Here's a link that shows the basic design:

Good luck :wink:

Alright, I have come back after two days, and I have decided to make a 2" tee instead, and my piston will be a 1 1/4" coupler. I've seen on many people's pistons, a black rubber disk thing on the top of their piston...what is that?

:lol:
You have a lot to learn

But that is the sealing face, so the piston can seal against the seat.
