OK, the base is a toy gun my son had. The barrel on it is huge, because it fired 2" balls out the end of the barrel. Its not going to look exactly like a Webley, so I'm calling it an EE-3ez.
I gutted the pistol and filled it full of Bondo for weight.
I JB Welded aluminum tubing inside the pistol barrel.
I took bondo and filled around the outside of the aluminum tube to make it conical shaped.
I've got to cut those slots out for my imitation MPP tube (that's what the white paper is on the end).
I have a guy at work making me a 1/4" thick aluminum stock plate.
...and then I have to fab the stock out. I have some nice poplar I am going to use. If you haven't tried poplar its really nice, looks like a hardwood, but shapes as easy as pine.
Comments are welcome.
