UDTBC-10 (my new 3'' piston valve)

[sjog]

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

ya but my piston is heavy the pill bottle is 3'' x 3'' and filled with epoxy-- thats why i used such a overkill pilot valve its a nice balance

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.
