Thanks, Intoodeep, I'll repost them under the Calendar selections.
DD - it's a collection of "I-wonder-what-this-would-look-like" playings on the lathe.
The tube is CRS with a way too large touch hole cut simply to see what a fire-cracker cannon would do.
The "wheels" were disks of scrap 1144sp made to see what contour would look good - different on different sides.
And the rest is a piece of 1"x1/8" strap iron bent to see what the form would look like - held together with scrap neodymium (rare-earth) magnets from DC brushless motors scrapped at work.
Recoil is MINIMAL, so it worked.
Inspiration was obviously from all the firecracker cannons made by our sponsors and the threads posted here.
Loading was a pinch of FFFg and then the fuse was cut off the fire-cracker, the fire-cracker pushed into the barrel fuse-end first and the fuse taken and inserted into the barrel. When lit the fuse ignighted the powder, propelling and lighting the firecracker, which exploded about 10' from the barrel. Air burst. 50' is about max range with this one.
Someday I'll look at it and make something similar in stainless (solves the cleaning issues) made up in a more conventional assembly.
This one took only a few minutes on each part and allows one to SEE what might could be.
