Homemade Ebolt???

I've been looking for the past two weeks at posts talking about the differences between ebolts and egrips, so dont worry THIS IS NOT A BUNCH OF EBOLT/EGRIP QUESTIONS... lol, just wanted to make sure the real modders didn't get annoyed and click off. I want an ebolt but haven't been able to find one anywhere and even if I did the part to replace anything would be impossible to find. Does anyone know a way to make one yourself? The electronics aren't hard it's the pneumatic ram I can't figure out. I've never seen the internal schematic so I can't design it that way. So anyone with any ram or advenced pneumatic advice would be extremely helpful.

Thanks

someday i would like to drop an ebolt in my 68 special, there is a whole lot of room in that gun to work with, especially if i could figure out a way to upgrade that old siphon co2 valve with a cvx valve.

i wouldn't want to do anything irreversible, i love playing with that made-of-lead monster
