Nicely done. Let's see the other twelve you've done.
Ha ha ha ! - Well, if you really want ! - Actually, I don't have photos of all of them, but here's an "Anti-tank gun" I built that was car-towable, which looked pretty cool, cruising around the town. it had a simple tube for a barrel, which actually housed a 12 gauge shotgun. This slid into the breech end of the tube and clicked into place. To use this you obviously removed the fore-end and the stock from the gun ! - We used to fire black powder blanks through it. The shield was made from 3mm steel plate and the spaced armour was aluminium sheet, bolted on with spacers. The wheels came from a Mini, mounted on part of a Mini subframe. The trail was scaffold-pipe. The spade was actually made from a boat anchor and required almost no modification to its shape. I built this in 1989.
That's all for now...... got to find the rest of my photos.
