JM Wild overhead milling / gear cutting drive motor.

[YouraTParticipant @yourat]

Hi all.

I've acquired after much searching a nicely built JM Wild overhead gear cutting drive system, but minus the motor and its pulleys.

I know the pulley diameters and the motor speed (1425rpm), but can anyone help with the as-designed motor rating?

I'm thinking that 1/2hp would be ample for my expected worst case load of pinion cutting, but any knowledge and advice would be appreciated!

Thanks,

Youra.

Yours,

According to Tubal Cain's book "Milling operations in the lathe" the JM Wild overhead gear used a 1/8 hp motor which TC thought a bit small for milling rather than clock gear cutting. I have used a similar arrangement with a 1/6hp induction motor that mills steel with a 1/4" cutter.

HTH,

Rod

Thanks Rob

1/6hp agrees with advice given elsewhere too – I have a slightly bigger motor to hand, and as long as it's not too heavy, I'll likely go with that.
