Raptor2 pump. First Project.

[Spleen]

im planning on doing a project over the winter... and i have a few pieces laying around. I need some tips on what to do.

1. Complete Trracer (pump) with a broken CA Adapter/valve
2. Raptor 2 with Hammer, Bolt, Springs, Caps, but no valve or cup seal.
3. A Marauder (soon, getting it from a friend)

I initially wanted to use the raptor2 body and make it into a pump, but im not sure on how i would get around to doing it as im not too keen on how pumps operate (i know how the trracer operates, but i dont know about stacked tube pumps???) Any suggestions? This is my first project gun.

you could turn any three of those guns into a pump. Theres a thread about converting semis to pumps

I came up with a great idea for this:
Take your valve out of your raptor and close up the hole that supplys the gas to the hammer to push it back. I would think welding it would work? I havent tried this but it was an idea. Then, after the valve is taken care of, attach some sort of pump arm to the hammer. You would need to make the pump arm have a long slit so after the hammer catches the sear, the pump arm wont come back and smack your hand thats holding it. I'll give some links on what it should look like.
