You mean you used that little fan to blow it across the floor? That's fantastic!

I'm pretty sure I found the contactor I used at the scrap yard, or it could have been a yard sale.

Yep it was still about 90 degrees f and without that it was not moving.

Out to the back yard. I was standing in the driveway taking the pictures

Yes, the wife opened her door on the car and handed it to me and said merry Christmas or happy birthday or something. You need this

On with the show, I had some time and worked on the control side of electrical on the lathe, I disconnected the input for the control transformer so I would have the fuses protecting the transformer if anything was amiss. I used the ohm meter and felt confident there were no direct paths to ground. So I ran the wires and connected them to the 220 volt single phase from the house breaker box and flipped the lever. 1 direction engaged and the other did not. this was expected as the folks where I purchased the lathe told me it only ran in one direction. Oh boy the $1,500.00 that the guy told me about the parts he found might be an issue.

The contactor for the coolant pump worked properly.

After this test The wires were removed from the breaker and the box cover put back on.

Time to pull out the trusty manual and look over the electrical schematic. I did find the drum switch that is connected to the lever that controls forward and reverse of the machine.

I used the ohm meter and found out the connection was not being made to fire the magnet for the reversing contactor.

Needle nose pliers and a 10 mm wrench made quick work of getting the drum switch out in the open. A loose contacting part was swinging freely and not making contact. It is of a fairly simple design on this switch, I had it fixed before I thought to take a picture of the issue, however, the switch is of a stackable configuration, you just stack on the parts till you have what you need, the nut had come loose ( is this the correct word for come from together?) the allowed the locating plate to let go of the C shaped connector to allow the contacts to be made for the reverse direction.

I lined up the parts, tightened the nut back down. 10 MM wrench and checked with ohm meter, all worked according to ohm meter. I put it all back together and wired up for live testing.

It works as it should.

Electrical issue resolved with a little due diligence.

a few pictures here

Overall view of control box

drum switch, 6 is power in, 7 and 8 are forward and reverse

directional contactors 7 and 8 go through the NC contacts to electrically interlock so power is not able to be fed to both forward and reverse at the same time.

The nut was loose and caused the plate to let go of the connecting part

Overall shot of drum switch.

So that $1500 ‘fix’ was a loose nut?

I think there’s an increase in the vacuum around here!!

Nice! Always happy when it is an easy fix like that.

What a nice sweet deal for $1500. My last lathe cost me that much and still had to pay shipping to get it close to me so I could pick it up. Year and a half later, finished rebuilding, trying to wire it up now to run.

Well I gave 400 for the lathe. The 1500 came from the previous owner about what it would cost for fixing the no reverse issue.

I picked up the motor to build the phase converter this afternoon.

Will that be a thread? Or, at least, a part of this one?
My converter ran for a couple of hours yesterday afternoon. My son needed to use my blast cabinet to prep some parts for painting which, of course, required my compressor.
After all these years I finally made him learn how to turn it on & off. It's dirt simple once you see it but not necessarily obvious if you haven't.
