Mock-up in 3d started of my BPM-11/9mm chassis project. Unfortunately I don’t have really nice 3d engineering software, so I am working with what I know, Autodesk 3Dsmax. I am modeling with polygons instead of splines which is probably not the cleanest. Still need to work out the joints and cavity shape for the M-11 as well as the charging handle interior. Lots more to do, but it’s getting to the point that I can start printing parts for test fitting. 🙂
My version of a bullpup rifle made from a m-11 pistol parts set begins!
I have started working on something that may be a relatively easy and fun build. A bullpup plastic chassis for a 9mm m-11. Here is the 2d mockup of the BPM-11 from Katzbalger Arms!
Use readily available m-11 parts and sten mags
Build the plastic chassis with a inexpensive ABS plastic 3d printer http://www.solidoodle.com/
I intend to build it in 8″ long sections and glue them together
If heat proves to be a problem for the ABS I can try casting stronger plastics using the ABS blank
Frame will remain steel and will be bent from a flat
Some welding required
Could be made from a standard m-11 receiver with sight removed
The overall size is to be slightly larger than a FN p90 (I find it just a bit to short to be comfortable)
Before I get too far, I would be glad to hear people opinions.
Next step is to design in 3D. I already have all the m-11 parts on hand, just need to weld my lower up.
Some of my latest personal work just getting cleared out of the way for a new 2013!
For the 1919a4
- I started with a Sarco 1919a4 parts set in .308
- Helbox Armory for the semi auto machining.
- Rivets from Burnt Capital
- Wells Custom Right Side Plate
