Pretty standard gun. To stop the TB from going to far just put a screw in the bottom of the barrel. BTW, that barrel is a little long for that chamber, bigger chambers are harder to ignite, found that out on my first cannon.

Nice gun and cool site! My only problem is that your entire Modification section is just copied and pasted from Burnt Latke's website! Perhaps just add a link to his entire site instead of a dozen links to all of his pages... I'm sure he wouldn't want you doing that. Anyways, great work on your cannon and welcome to the forums.

not very safe, putting your face in front of the barrel
also i note that the the gun is made not out of pressure rated pvc, or even DWV pvc, what fitting is that?
that cap looks very thin, be careful

Yeah man putting your head infront of anything that shoots a projectile is just a dumb idea people can get maimed or killed, by accidents.
