This is great. Pull your ear straight out to the side of your head, grabbing it by the tough rim area. Don't yank it, but just start pulling and increase force until it CRACKS! Sometimes I have to pull so hard it takes both hands and a t-shirt between my hands to get a good enough grip! Give it a go...

I *could* make this design fo the price of getting pipe bent and maybe a few "o" rings. The major part is the time sourcing free materials (which can be done btw) and my time machining the parts. Total cost would be around $20 and a carton of beer. If labour AND materials were included i would quot...

Someone said they could make the whole gun for $600 though I thought? I think materials alone would cost more than half that.

I took some video night shooting, hoping that the green laser beam would be visible to the camera, which it was not. On top of that, I MISSED like all but 2 shots! Looking forward to making good sabots. Of course, much of it is my fault as well. Holding still is hard sometimes. All shots were at 50 ...

That thing is friggin awesome! I love the hi tech look of the whole set up. Videos are desired in a way that can't be overstated. Tennis ball caliber for a beast that size...safe to say it belongs in the "ultimate" category

Some nice work with AutoCad there. Some of the parts there look a little generic though. Have you figured out the real world parts and interconnections that would make this thing real? Right. Its a lot of fun to let the immagination run wild on a sweet design, until you realize that 95% of the part...

I like this idea. I bet it would go really far. You even make a rifle with this setup. Just have the nail attached to a rubber band or something and pull it back somehow and BAM! You could make a semi-auto CO2 rifle! Edit: Oh, about doing stupid stuff...I would have to take the cake for that one, ha...

How does the arrow get throught those rings?

Just wanted to update my progress on sabot refinement. I went out last night to do some night shooting and tried some new sabots, and they basically sucked. I will now make a simple mold out of some plastic pipe and glue a golf ball to it and pour in some strong arts and crafts molding clay stuff I...

YES! Thw back packer pelet pistol kit FTW!! I used to love that thing. Nice cannon. Impressive muzzle!

Its not for the contest. Its just a design idea.

Thats a beautiful model! It nearly brought a tear to my friggin eye. I love seeing this stuff. I love the design. Couple questions...is that a standard return bend or are youn planning on hiring a tube bender? Also, the barrel support looks like its cantilevering too much for sturdy support. Is the ...

Here is my progress thus far in a do-it-yourself version of an over under style Combustion/Hybrid design. It will consist of standard parts that can be ordered online. What is shown is a 3" chamber, 1 1/2" barrel and 2" camlock. Of course that can all be increased for more cost and weight. The desig...

I like the hand grip. It looks like a supersoaker/spud gun! Any chance of video?
