I used the Asco as my main valve and got 500fps so your piston must have some good numbers

Hi,

OK looking at it again, those 8 * 8mm bolts of mine are in a 75mm ID bushing around the tee (I forgot).

In any case, just go shooting with it, and if you - after having it apart for a few times - notice that the bolts have exerted a lot of pressure on the plastic, maybe get some larger ones. They looked so small to me on the pictures.

Regards
Soren

Hey I'm going to build a cannon like this. I just have a question about the parts list for the "tee" and why the bolts are. Could you give me a walk through on that area.

Dude, this topic is almost one month old. Don't post in old topics unless you have something useful to say. Just send the person who made this topic a PM.
