I'm in the middle of building an assault rifle, it will have a qev single shot mode, a vortex block full auto mode, and a grenade launcher. So far everything is finished except for the grenade launcher, which will be a diaphragm co-axial. I think I will have it finished in a week or two.

Me, nothin’ much, just building a prototype auto-cannon, and designing 6 more :)
The prototype should be finished by the end of the week, provided all goes per planed and I get off my lazy butt…

Hey that reminds me, I’ve got a flop to post…

Everyones projects sound really good, and Im looking foward to seeing them all.

I'm finishing my semi-auto paintball gun, which is going well, and will hopefully be completed in the next few months (its about 52% complete(that was just a guess)) :wink:

I am now starting on a prototype(ish) valve which includes a "hammer-piston" valve; hence the (ish) :D that is only in its early stages though, and could be a while...

Currently I'm getting parts for a hybrid torture test.
The goal is to find out what it really takes to fragment 2 inch sch40 steel.
(No, I'm not going to blow up my hybrid, I'm going to make a closed hybrid chamber and crank up the mix until it pops)

This will of course be done in bunker. If I can't get it to explode(I'm limited to about 8 or 9x), Then I will adjust the spark gap placement to attempt DDT.

Not sure if I will be able to get a video (potential damage to camera and all).
I'll try to see about getting some lexan to set up a camera behind.
Either way you can still expect pictures.
