Thanks Bernd, that sounds like what I was thinking of. Seems like there are both ratchet and fixed types
Got her wired up and running, sweet as a nut and very quiet which I was not expecting.
Sorted the bed x axis rapid speed motor switch that was hanging off the machine. Turned out to be dirty contacts that were arching. A quick spray with some contact cleaner and a good wipe over soon had that sorted out..
The slow speed transverse motor was not connected, the wires were snipped off inside the turret...Odd..? Not done that yet.
But, the DOL (starter switch) keeps tripping out after she has been running for a short while. The motor is not at all warm, seems to run sweet enough so I suspected the switch unit.
Opened it up and it seems the thermal cutout is rated at 1.1 - 1.6 A. The motor is rated at 2.5A. Now I don't know much about 3 phase electrics but this does not seem right to me?
I suspect this switch is for the slow transverse motor and not the main spindle motor.
Therefore I need another starter switch.
Good job someone has just donated one to me, in fact it's a double so will do both the spindle and the slow transverse motor.
But it needs a 12V circuit to remotely operate it. Guess what I found hiding inside the knee, yup a 12V transformer....fancy that....

Next question, what type of switch do we use for the 12V side? Surely not a household light switch......
There are a couple of other very minor issues to be sorted. But overall it seems to be in fine kettle so far.
Oh, nearly forgot, the draw bar is the wrong one. Needs machining to make it fit. that's if it's not too hard a material.
