What size or type of pipe ABS, PVC or Conduit fits lacrosse balls the best. And what is the difficulty of finding one of them?

Thanks in Advance

It didn't run off the dober, it was a consistency of jam. Thank for the help, I appreciate well thought out answers.

The primer made it soft, but the cement was a jelly consistency.

I have built a pneumatic gun, and I have solvent welded it with primer and cement. I made sure to put an even layer of cement.

But is was pretty jelly-like, and I realized that this is bad now.

So my question is will I still be safe, I made sure to spread it evenly and apply pressure.

Help ...
