I feel bad for leaving you guys out, so here goes:

A while back, I began working on a bouncing betty type landmine. While it looked good, I just couldn't get it to function properly. The primary goal of the project was to create a mine that looked as much like the real thing as possible while still providing its intended function; in this case, launch a standard paint grenade into the air approximately 4 feet then set it off.

After extensive tweaking and testing, I just couldn't get it reliable enough. Out of, say 10 fires, it would function properly about half the time.

Here is a picture of that particular version, with a side-by-side comparison of the real thing:

The first problem was the triggering mech. I got it to work, then another problem arose. It operates from a 12g cartridge and is designed to hold pressure until enough is built inside the body to launch the grenade. I guess if I had proper machining equipment, I could make it reliable, but I just couldn't overcome the pressure buildup.

Now, the reason I'm making this post is because I've decided to scrap the whole "look-alike" thing and make this work. I've incorporated several techniques that have been proven to work. In then end, I will end up with my bouncing betty that has a smaller profile, easier and faster to set up, and will be cheaper to build. When this is complete, I will post a video of it for you guys.

Sidenotes:
- I've began work on a 12g powered claymore mine. It will be tripwire activated, cover at least 180 degrees in one direction, and take only seconds to set up. This one will probably be finished before the bounding mine and I will post it up when complete.
- I've began working on a pressure activated mine. It, too, will operate from a 12g. It will have about a 6 inch pressure plate and be about 3 inches high. Setup for this will be even quicker than the claymore and it will cover a full 360, although it will be designed for single-person elimination. This is still in the design stage as I will have to use techniques that have not been used before (read: I got some experimenting to do), therefore, it will take some time.

good luck wit the betty

gee too bad you arnt near Louisville Ky or I would help ya with this...I have done similar things in the past that could possibly work...it is a lot simpler to show in person though but I love these types of challenges and ideas can't wait to see what progress you make

looking good! rep4u

Just thinking about the pressure mine, a bunch of others I've seen just have the single pore that will castrate someone if they're positioned wrong on the mine itself, but I was thinking... You could try make another section ontop of that single pore leading to a bunch of other pores that are pointing in a few different directions, which are filled with a paint mixture. You can still have it pressure activated an' all, and you could get more people hit by it too. If made correctly it would work, be reliable and safe. (less castrations and pressure injuries. (if any actually occur with the mass produced pressure mines. (only seen one on youtube work and it looked like the tester's balls took a good hit.)))

I just thought that might work a bit better, but then making it would be a bit more complicated... Just thought I'd try and help out. :P
