    Old induction motor - direction reversal

    Yes the pulleys ratios are right for that. Hmm but I have a little 3-jaw chuck, too tight to buy a bigger one, and I have big chunks of the cherry tree that fell over! :) Remembering when I did my workshop training, way back, and bounced a 12" x 12" aluminium workpiece off the roof girders...

    Old induction motor - direction reversal

    Thanks for that - but the detail of that post is for a version with capacitor... not sure what to do with this one, except follow his advice to carefully take it to bits...

    Old induction motor - direction reversal

    Thanks for that! Attached photos of the connection box. A is not connected to anything, by ohmmeter. B is neutral power supply D is live power supply, current then goes out through thermal switch and back to C C is a red wire into the motor E is a yellow wire that comes out of the guts of...

    Old induction motor - direction reversal

    Hi all, Motor gurus advice needed, please! I have an old Coronet Major lathe, with an original type 2850rpm motor. Even with the belt set to lowest speed, it seems too fast for any turning over about 4 inch dia. So I bought a newer motor, made by AEI, same size, single phase, 1425rpm...

    Coronet Consort chuck recommendations

    On the red Majors, the 7/8 x 16TPI, does anyone know whether that is a Whitworth or UNF threadform? Thanks, Rupert

    Sorry just to add one more thing, is the 16TPI thread a Whitworth pattern (55deg angle) or a more normal 60 deg pattern? I couldn't yet measure my spindle, but I think it is Whitworth?

    Coronet Consort chuck recommendations

    Hi, sorry for late reply, had a few things going on... I had prices slightly higher than that, but I think you need to add some features to the adaptor. The thread is just part of what is needed, it does not locate the parts. For that there is a register diameter and face, these exist for...

    Coronet Consort chuck recommendations

    Hi Dalboy, Thanks and you are right, that is stocked. But they are a bit premium priced for me, and the Sorby has a M38 thread on the chuck itself, so once you have that insert, you are kind of committed to Sorby. But with an M33 insert you have a wider range of screw chucks, second hand...

    Info on Coronot Major lathes

    Hi, my maroon Major has the same motor, 2850rpm. The capacitor is marked "60-80 UF (microFarad), 275V RMS". It looks too shiny to be original, but it works fine. Regards, Rupert

    Coronet Lathe

    Hi Northerner, Bit late to reply as you've got the 4 prong drive ctr out. But on my maroon Major the spindle has an axial hole drilled along the length of the spindle, so with a bit of bar, maybe 8 inch long, you can stick the bar in from the back end of the spindle, and the centre comes out...

    Coronet Consort chuck recommendations

    Hi all, I'm brand new to this forum, in last 5 minutes! I also have an older Coronet Major with 7/8 thread chuck spindle, and the same question, and no success in finding an adaptor. I have done a design drawing for an adaptor to M33 x 3.5, which is used by many Continental chucks. I'm sending...
