cartridge fed pneumatic - ideas for refinement

Unread postAuthor: jackssmirkingrevenge » Fri May 11, 2007 2:25 am

I've thinking of giving this concept another go.

The main improvements will be combining the existing mechanism with a valve similar in concept to the pop-off piloted piston valve in markfh11q's marble gun to give automatic fire.

I would also like to make the breech longer in order to give the cartridge more travel, as Hawkeye had suggested in the original thread - this will hopefull result in worthwhile power levels. To that end it would include a bigger chamber, and perhaps a check valve between the pilot area and main chamber would be a good idea to allow maximum pressure to build up in both chambers before the pop-off actuated the piston.

Is this a "heads up"? Anyway, It sounds like a good idea, I look forward to seeing it.

It's a "here's what I had in mind, anything I might have missed?" :wink:
