yeah, my compressor is on its way out, so it takes a good while even on a full charge. i need some bailout money...

since it takes about 5 minutes minimum to get the gun ready for the next shot, i don't really have to worry about overheating. it doesn't get too hot each shot, because the ignition takes place over such a short time with this small of a chamber

i believe the aluminum tank will suffice for now. it's surprisingly thick walled, and built to have constant pressure held inside so we know it's built well.

that's awesome. i used to make a piston holder out of a hole-saw, and just spin it with a drill while i pushed into it with a file

here's my next project by the way
on the left, is another 20 oz. co2 tank, and in the middle is a large oxygen tank. very high pressure rating=very fun gun

This is my first post, so please pardon any mistakes. :D Around the beginning of the summer, i decided to start working on a hybrid. Since i didn't want to be restrained by the relatively low pressure tolerances of plastic tubing, i chose to use a 20 oz. cO2 bottle for the chamber. having a minimum ...
