...Right there with you on the noise/cleaning issues!

I know next to nothing about hybrids, and I've seen it suggested at least two or three times by JSR and others But here goes: A 'shell' precharged with mix, with a screw cap securing a coke can base burst disk up against an 'o' ring for sealing. The screw cap is turned on a lathe with a reduction in...

This is the latest launcher I've come up with.
It runs at relatively low pressures but is still able to launch projectiles of varying densities quite some distance...
It's been cleverly designed to fire in multiple directions, sometimes simultaneously.
Tell me what you think!

Pneumatic spearguns work on the same principle. I've wondered about the same idea but mostly just to reduce the time spent making/finding sabots. One idea I came up with was to have 30 feet of string coiled up in a hollow base that could unravel as if flew through the air and make finding the bloody...

It appears that the 4-stroke charge cycle idea has had a 'failure to launch' :lol: It just seemed that the engine manufacturers have been working on the high cyclic ROF (rate of fire, not rolling on floor...) problem for us for the last 150 years. (Rolling on floor I can do!) The next topic to tenta...

Bugger.

Thanks for the links though!

You look big enough (in the monster slingshot video) not to need all that!

Is Germany really so dangerous? I was wanting to visit sometime but now I'm not so sure!...

Just hope the welds don't fail and fire the blades backwards! Ouch!

For the Girandoni style proposal, pretty much any thing that you see here would suffice: :shock: http://www.youtube.com/watch?v=PgdfMa8caNg So long as it splits a 2x4 at 50m. :lol: For freedom, take away the requirement to work using a cam, (to allow blowback or other actuation) and for focus (and t...

How about jaegers idea with the 'o' ring above and below the chamber extended up the barrel multiple times like inonicknames idea by making a 'rocket' length projectile more than half the length of the barrel with four or five 'o' rings and (at 1x) ignite the whole bloody lot simultaneously so that ...

Rubber pull-through schrader valve with the valve unscrewed and discarded, wire goes through, then fill with... you guessed it... epoxy. Good for metal combustion chambers, and pressure rated! :P Or bolt with (or without) point goes through wall, tapped or not, with a nut on each side, and filled wi...

Hi Guys! I've been pretty busy the last 4 months (...3 and a half month old son! :P And a new mortgage :? ) but I read this thread last night and was pretty darn enthused (like everyone here by the sounds!) So in the spirit of idea sharing here are two quick ones to throw into the ideas "pool". #1 I...

Yippy kai aye mother plucker! :o That's blurring the line between potato gun and big bore airgun! (...Oh for some way of making rifling! :cry: ) I love it! :P It looks like you could, (if you feel like it's warranted of course,) move your foresight to the end of the barrel to give a slightly longer ...

Hoi Sniper Hero! Make sure you start with a piece of timber that is wide enough! (..my stock broke during construction...) A bandsaw is great for roughing out but not everybody has one, the single most useful thing for shaping would have been one of those sandpaper disks made of many 'flaps' of sand...

Will this platform allow for modular barrel assemblies? If so I wonder what kind of velocity you can get with 6mm .20g Airsoft BB's. Hey David, Yes, the front of the 'action' presents as a standard 3/4" female pipe thread, so all manner of things can be made and screwed into it, as soon as the barr...
