I would normally recommend more than the d/4 rule, because of potential piston bounce, and just to be sure really


I will probably shoot for around a quarter inch both to make up for possible bounce and the fact that I may screw it up, seeing as I cant look at the seal from the side now that its soldered together.

But in this case, the piston doesn't sit in the tee itself.

I wondered if anyone would notice that. the reason is, I don't get how you "bore out" the tee without weakening it? I wanted everything full strength. Its like barrel rifling, how can that not totally weaken the pipe?

By the way, I have no clue how to get the quote thing to work, so like a resourceful noob, I used the ole' copy paste trick :D
