Refurbishing a Delta 930 Lathe

[ededic]

Glad to help!

You made great progress! Nice terminal crimps and heat shrink.

If you look back at the motor wiring diagram, for 110V, you see that red and yellow go into one ac lead, and black and white go into the other, so on your switch, you put one ac lead on either red or yellow, and the other ac lead on black or white. Usually, I pick whichever side of the switch has the most room, usually the side away from the motor lead entry. (Like on yours, red gets one and then whatever color is on the bottom that side (black? I can't quite tell in your photo.) gets the other ac lead.)

The really important thing is that you don't want to have the AC leads side by side on that switch, or they will short.

Does that help? Just for the record, I am not an electrician and I don't play one on TV...

All the best,

Peter

Peter,

Thank you. Worked like a charm. The one thing I needed to do was individually tie nut each line at the motor. What is obvious to me now is… the way they are tied together in the picture below is if I did not have the drum switch.

You made it as simple as possible and I can’t thank you enough.

Awesome. Had to do a bit of super glue on the cheap safety switch housing. The screw posts broke off I put arrows to them glued back on in the picture.

So… will have to wait until tomorrow to post pictures of the finished product.

Thanks again Peter. So happy.

You are welcome! I am always happy to help.

Once you start using your lathe, I would love to see photos. Despite having made a few items on wood lathes over the years, wood lathes and I have never been super comfortable with each other. I know that I could use a few more bits of wisdom. I am impressed with what other are able to do.

All the best,

Peter

I purchased this antique lathe, then found an original set of cast iron legs for it. I built the connector planks and feet out of Red Oak cut and sawn from the location where my woodshop stands now. I purchased a new motor to be trouble free.

There were two Delta lathes in front of the windows in our high school wood shop. Somebody took out a pane with either a chisel or a flying piece of stock. That was over half a century ago and I guess those lathes are antiques by now, too.

Stuckmotor, yes I hear you and others. Can only use the reverse when using the tail stock so it cannot unscrew and fly off. This will be my first time using a lathe since HS shop class.

Looking forward to trying it out. Need to go pickup the V-belt for the drive today.

If you become interested in turning bowls check out Phil Anderson's videos on YouTube. His approach is very straightforward and informative. You should enjoy turning. Sometimes just making shavings on the lathe is therapeutic.

Nice job. I have the same lathe that I got from my uncle.
Also in the process of rebuilding my Atlas 10" metal lathe.

All buttoned up. Ready for the drive belt and making some chips.

Thanks all for the comments and encouragement.

By the way, often all the old motors need are some new bearings, a little dust removal from the windings, sometimes a new capacitor, and you are back in business. Easy to do.
I had an old Walker-Turner motor whose motor leads had crumbled, and they needed to be replaced which was a little more challenging as the original wires had been silver soldered together.

Don't get me wrong, newer motors are often far more efficient, but sometimes for the sake of historical accuracy, the older motors can be worth the effort.

All the best,

Peter

Unless the windings are bad, rebuilding an old induction motor is pretty simple. It would take a lot of hours on a big motor for efficiency to pay for buying a new one.
