South Bend 9 C Lathe Restoration

No. If the tapered pins are too long, you could always trim them off. Roll pins would require that the hole be drilled the same size the entire length.

Nope. The roll pins tapped snugly right in. I notice the tapered pins are soft metal and I figured they would sheer off instead of damaging a gear. The tapered pins are not proper as they only go in about half way.

My South Bend 9C "Blue Wheel" 1945 lathe. All I'm waiting for is my motor drive pulley so I can align and install the motor. I might have to order a shorter counter-shaft belt because I'm going to be a little closer to the lathe bed when motor installed. I'm going to pull that motor mount bracket off and paint it. I didn't notice until I saw the picture of it.

Today is a day of bad luck or should I bad stupidity! Found a v-pulley, that I didn't know I had, and was trying to put it on the motor's shaft. Well it was a little tight so I thought I would take a rubber mallet and force it on. "Weeeeell" after beating it into submission the motor doesn't work! So tomorrow I take the motor apart and do some field coil testing. Being over anxious causes bad moves. "DUMBER THAN DIRT!" I probably bugard the centrifical switch.

I fixed the motor centrifigul switch and works as it should now. The plastic shaft part of it was cracked. Welded/melted it up and works just fine. All I have to do tomorrow is wire in the switch to the motor and I should be done except for that pesky little tiny brass piece that no one knows where it belongs.

UPDATE: 1/1/20 I had to order a 2" shorter flat belt because the one I have, 50", rubs on top of the motor.

Wired in the motor to the switch , added on a threat counter and did a "first cut." Really cuts nice. Took care of some rattling noise makers. Once I get my new shorter flat belt I'll be able to tighten it. As is it's only the counter-shaft assembly puts tension on the belt because the turn buckle is beyond it's limits to tighten the flat belt.

I can't figure out how to tighten the flat belt! When lengthening the turnbuckle all it does is push the release handle forward. Am I missing a part that will enable the release handle not to move and tighten the belt. I made a spring apparatus to pull back on the counter-balance assembly to tighten the belt. Before all I could cut was .005" and now with the spring I can cut .020" without belt slippage. Gotta find a better spring but it was all I could find at the moment.

This is what a factory 9A horizontal drive looks like.

My release handle will "flop" all the way down to the back of the lathe bed! Is there a handle stop that I might be missing?

 

[DavidR8]

What does the handle look like on yours?

Your pic is too dark to see what's going on. Can you use your flash? Here's a pic of mine and I don't see any stop. Looks like I'll have to machine out a handle pin cause there's too much play in it.
