I believe that I've found the problem. First of all I found the reversing switch, hidden on the RH end of the bed, in its own little housing. As it's only about 9" away from the wall on the RHS I've never had cause to look at that view of the lathe since it was planted and hadn't noticed the switch location.

Anyway, the switch mounting screws had become loose with the lower one completely out of its thread in the back of the housing, causing the switch to pivot on the top screw and move away from the "forwards" actuating cam. Because the upper screw was still, mostly, in place, it served to hold the switch sufficiently for the "reverse" cam to actuate the switch. Why it would appear to work in forward after a rest period I don't know.

Sadly, only the upper screw will hold and the lower one won't tighten, so I'll have to deal with that but at least the lathe now seems to work OK in both directions but I'll do some work on it tonight and see how it performs. Also, now that I'm listening for it, the centrifugal switch can be heard operating properly (in both directions) as the chuck slows down to stop.

Thanks to all who contributed and participated in this discussion, you've been a great help to me and I've learnt a few things from it.

Thanks for all of the suggestions, they all have merit. I think I'll begin with checking out the reversing switch as it seems the logical culprit, does anyone know where it resides? I can't see any reference to it in the parts book?

And with regard to checking out the centrifugal switch, I'd need to identify the appropriate terminals first. The wiring diagram isn't exactly clear, at least to me!

Ahaa, Thanks, that answers the next question of whether the motor has a centrifugal switch. How easy is it to access the switch?

Thanks

Hi Folks, I have a Warco GH 1330 that has worked well since new 9 years ago but last night it wouldn't start forwards but would start in reverse. Leaving it for 10 minutes (presumably allowing it to cool) then allows it to restart forwards and it will then operate properly for perhaps 10 minutes before again refusing to start forwards.

In other applications this sounds like a capacitor starting to break down but I cannot get my head around its willingness to start in reverse when it won't start forwards.

Does anyone have any experience of this type of event that may shed some light on this?

Thanks in anticipation of some useful knowledge.
