Re: Air Rifle Stock Help

I thought about it, and decided that I am going to make my own stock. However, the design i had in mind requires a lot of interior cavities for parts such as the QEV and chamber. I believe that this would be extremely difficult to carve out of a block of wood. Any recommendations? (Also, it would be...

Air Rifle Stock Help

Hey guys, I'm currently planning to make a QEV pneumatic spud gun that fits an air rifle stock. These are the stocks I'm looking at: http://www.gamousa.com/family.aspx?familyID=68 (BTW: I know that I could create my own stock, but I am simply terrible at woodworking) I have several questions before ...

Overtightened NPT Threads

Help! I have a 1.5" pneumatic aluminum spud gun, but I think I screwed on the pipes a bit too tight... There are 3 threads left visible on the male threads and I'm scared it is too tight and will go BOOM in my hands. They are aluminum 1.5" pipes and fittings from mcmaster.com

Thanks a lot guys!

I think I tightened one of my aluminum pipes too much, as there are only 3 visible pipe threads left. What happens when 1.5 inch aluminum pipe is over tightened or under tightened? Thanks.

Hey guys, 3 questions :) What tubing do I need to connect the butane canister to a syringe? (an amazon link for the syringe and tubing would be REALLY helpful :D) How is this kind of sparker wired and what type of wire is used? The ones I saw on amazon just had 4 electric dots (whatever they're call...
