nice, can't wait to see it completed, have you fired it through a chronograph yet? if so what were the numbers like? I've been really wanting to a PCP air gun build, but have a lot to learn about designing a valve/piston system that will function correctly and not dump all the air in one shot. Nice work, Keep it up! Great job on the stock BTW.

@ak74u2 haha you guessed correctly, i couldnt find anything else in the room to hold it up besides the vb can.

Awesome gun, epic music, and great video! Some constructive criticism though:
1) If you don't put a groove in your piston you'll get higher power, air will still leak through much slower.
2) Your piston looks like it was made of hot glue, try your hand at casting one from epoxy, it will provide less friction therefore faster opening times. It also won't expand on those really hot Australian summer days (I know this from experience).
3) I recommend you check out spudfiles if you haven't yet. :)

@SketchyAussie hey thanks,i did make one out of epoxy but it was stuck in the brass fitting so i decided to stick with the hot glue piston.
