Alright reed I might put it on my bbmg.
@chinnerz it isnt really that hard, plus the handle makes it a nice grip so it is all good. I dont know about a vid, its nothing special. Can get through a few layers of paper with ease but not cardboard.

Clemsonguy I never understood how it worked, what do you use for the shaft? I have a chapstick tube but I dont want to ruin it for nothing.

Ok, google chapstick pop gun and make that, I won't explain since there's hundreds of videos about it, then pull back the shaft and drill an hole rightin front of the piston.
That is all.

This is a lot like my
first combustion. I added a bike pump, it doesnt suck out old air thats not how a pump works but it does pump new air in and push old air out. But I would recommend putting a little fan in it its easier and it helps mix.
Patience is a virtue, get it if you can, seldom in a women, never in a man.

Well my chapsticknisnt really a pump since it doesn't have a 1 way valve, it just removes old air and brings in new air, I don't know what to call it
That is all.

well if theres no oneway valve its just a like a pneumatic cyinder, you wouldnt bring any new oxygen just move the air inside the gun back and forth.

I'll suggest you trying to meter butane with it, it'll probably make it 30% more powerful, it shouldn't be hard at all. Also if you want a pump you could put a small syringe, connect to your chamber for pumping, and simply add a valve between the chamber and the syringe so it can be closed off/on before and after firing.
If you don't feel like measuring your chamber volume and calculating the amount of butane required you can simply connect a little butane cartridge found in lighters to your gun. Then count 1 potato 2 potato 3 potato, until you can find the sweet spot for your gun.
