Since I already have the machinist working on standard 18650 tubes... I think I can get Henry to agree... would only be for Rotary acme threads... and would probably be stupid expensive (well hell, most of this stuff is stupid expensive).
I shall see what can be done and for how much for how many.
In fact, why doesn't someone start an interest thread on the topic and let's see where that goes.
18650 is my preferred battery format, and I'd be in for at least one. Maybe two depending on expense.
