Looking forward to those videos :shock:

If you define a hybrid (as we do on the forum) as combustion of fuel vapour at a pre-ignition pressure significantly higher than atmospheric pressure, most cars are hybrid drive ;)

Quick video

I think this is the first video footage I've posted of this gun... ever. Unfortunately when I was visiting ohio I did not have much time to shoot stuff... otherwise this would have been a bit more extravagant. I had to quickly macgyver it back into a working condition with few tools available. Some of the stuff I filmed couldn't be used since it was too dark out.

That is a very satisfying bang, good on you for wearing ear protection :)

I agree with JSR, it's a VERY satisfying bang. Good job! :P Just wait till I achieve that with a pneumatic cannon... :D

This might be relevant to you:

Here's an interesting design for people wanting to test loud devices without actually fitting a suppressor to their launcher:

The latter can be an oddly satisfying experience though... für die Wissenschaft!

This for example made my day, it didn't ruin it :D

New .40 cal barrel on my pellet gun, I think it's fitting for the sawn off configuration

Have you considered a valve upgrade?

I hear there's a few guys on the forum handy with a lathe ;)

It's got a good amount of power as is, I just have a problem with the skirts on the blowgun darts flipping at higher pressure. But with just a single pump, this thing puts wire darts deeper into wood then my 48" blowgun.

Here's a video of it a various pressures, you can see the skirt flipping problem in some of the higher pressure shots

Assuming that the exploding gun wasn't immediately lethal and didn't cause paralysis or other permanent disability, I'd take that over the police any day.

Nice work, Fnord. I'm looking forward to coming across this build somewhere in the 800+ new posts I'm slogging through after frosh week.

I got sick of my harbor freight consumable threaded hole plugs, so I bought some better taps and dies from ebay.
My tap and die set now weighs more than a small child.

Oh, by the way DYI, that gun is my *old* hybrid, so there's nothing new to see here. But I do have some upgrades underway that should get the power up to multi-kJ levels, finally.
