"AA" Coaxial Piston

[)DEMON(]

Get a reducer and cut it into sections then glue at least three of those around the barrel. I call that a barrel stabelizer. My piston cannon also needs a bit of work, all I have to do is move the piston back and get a longer barrel.

home depots don't carry neopreme but for a small gun you can look in the faucet scection for repair parts. get rubber disks fith the hole in the center

I can't find 1" to 1/2" reducers at Home-Depot, I guess I'll have to go to Lowes to get thoose and maybe Neopreme....

I though about using 1" to 1/2" reducers, but I'd have to butcher them for it to work, I'd have to take out the stop on all of them, and take off the flush park so it'll slide in the 1", and then I'll have to drill holes in it so my whole chamber will be used, but how would I be able to keep them in place?

How did you heat up all that glue? Blow torch?

All that glue? lol, it's only about 2 in² (~33 cm²)

It's about 2.5" (6.35 cm) that's close to 1.033" diameter because it seals in 1" pipe great...

I used about 2 and a half glue sticks that I melted with a glue gun into 1" pipe cut to about a 3" length with a few layers of magazine taped to the bottom and the inside lubed with some Cooking Spray not Olive oil like someone thought...

You want to Mold about the whole 3" and then cut-off the ends because there a little un-even, and I sanded mine with 320 grit sandpaper on the ends...

Note:
If you make this piston for 1.25", 1.5", 2", or 3" you'll want to make the piston longer accordingly, so you don't have a 3" piston that's 2" in length which would be unstable moving in the pipe, so if your making a 3" piston, make it atleast 5" in length...

The glue piston on this thing has given me many ideas... thanks.
