Thread: Bigger knob, shooting smaller bullets.

Cheapskate as ever, that's the fun of tinkering.



What do you do when your roll-on runs dry? Recycle its 33mm hollow plastic ball to go over a 20mm milspec one

Cut hole, a bit too small so cracked, never mind, had to superglue it into position anyway. Oversize hole used to squirt in gorilla polyurethane glue. this will expand into a lightweight hard matrix and extrude thhrough the hole. The material can be trimmed to size around the base of the knob, will be easier to do before it goes all hard. Then paint.



Second project today (which really makes zero financial sense given the prohibitive cost of 7.65x17 Browning, but one local range won't allow bottleneck cartridges). I have a 12G adapter for the 7.65 cartridge made out of an piece of .303 H barrel and it works fine in the .303 bore.



.303 case, 9.5mm drill out the rear, turn some black mild steel to fill the gap behind the pistol cartridge, drill a firing pin hole including pocket for the nail used for this. Round off the tip of the nail so it doesn't pierce the primer. I managed to tip the items on the floor several times already, including into a box of junk metal... )-:< so... a bit of tape to make the nail less prone to jump ship.

I'm thinking, I could also turn a groove in the breech piece for an 'o' ring to make it less likely to drop out of the .303 case.
