Why do you need reverse on the mill? Knee raise/lower motor, table drive left/right motor. Head raise/lower motor. Tapping head with friction drive (not auto reverse) in the spindle.

Thanks for the reply - but mine doesn't have a motorised quill or Knee raise/lower. My Mill has spindle drive motor and table feed motor left/right.

There must have been a reason for them to design the machine to have the main spindle motor to reverse.

NB: New Rotary switches installed and have just order two new Auxillary contactor blocks NO/NC type to control the other contactor. I think I will soon be ready to use the Mill - after almost 6 months of restoration and heartache.......money...... time....and trouble. But its worth having this almost 70 year old machine back up and running.

Its alive - and works perfectly.

Took my first cuts last night and its very stable. I machined a few bits of mild steel with a nice and sharp brand new end mill. Only took 10thou cuts to start, slowly built my confidence and went for a 25thou cut at 15mm deep. Looks good.

The fun begins.

Thanks for all those that helped with the new switch wiring it works perfectly and now no chance to put the motors into reveres by mistake.
