I'm making a SnapBow, and I can't seem to cut the nail the right length on my trigger. Does anybody have a picture of how much it should stick into the tube? or a Length would be even better.

It should protrude somewhere around 1/8" into the plunger tube, perhaps a bit less.

I had the same problem. Most of the solution lies in the amount of sanding you did to the endcap. The farther you can get the nail to be sticking into the tube, the better, because it will catch stronger and more easily. I have found you can go even bigger than 1/8" if you sand down the endcap more.

I use curved endcaps, and I find the following to be perfect: sand off the injection tab. Then, cut around the lip left by the molding process, rounding the cap down slightly. I also insert a small ring of 3/4" pvc (1/8" long) into the cap before I add the plug/washer assembly, which works wonderfully.

What is this injection tab you speak of? I can only get curved end caps that have nothing raised on the outside at all.

Just an uneven bit on the outside of the cap, left over from the molding process. It keeps my caps from fitting cleanly into 1 1/4" pipe. Yours may be manufactured differently, by a different company.
