Bat model b thread ??

[Rockchuck]

Could anyone tell me what size thread wires and the over wire measurements for a bat model b action. Thank

.032 wires should be right around 1.071 is what I’ve gotten written in notes. Haven’t used wires in years moved to thread mic much easier

1.071" with .032 wires is a good number for threads, a couple tho' less won't hurt anything. Keep the tenon diameter under 1.062, I turn to 1.056-1.057.

Machinery Handbook is valuable to have. Also, lots of searching and figuring out can be minimized by visiting http://theoreticalmachinist.com/

I have a BAT machine 1-1/16-18 tenon they sell as a go gauge with the pitch diameter engraved on it. I will update this thread with it.

That thread calculator is a must have.
