Nice rig KV.
Although my 14500 batteries are still on the slow boat from China, I've been looking hard at ½" copper pipe and caps. I can't check for fit until I get my batteries but I'm thinking that will make a sweet and compact single battery 801 mod with an insulated spring and microswitch set into the bottom end cap.
Thanks CH.
Sounds like a good plan you got there.
I've got the 1/2" but had the cr123 batteries so had to go with the 3/4".
That really should be a great rig. Those batteries should fit exactly.
I've got to order some 14500 batteries. Might just bite the bullet and go to that Battery Junction outfit.
