I have an older 13" LeBlond lathe, and the brake has never worked for me. I'm not sure of the exact year of manufacture, I'm guessing that it dates to the 1960's. (Serial number is 4B1166 - Is there somewhere to look it up?) It is a manual shift model not a servo, if that makes a difference.
Here is a photo of the diagram for the brake system:
I have a little experience with electrical work, probably just enough to get me in trouble
. I've done a little snooping around, but I didn't find anything obvious and this stuff is a little over my head.
So far, what I've found is that there is 53 VAC at both terminals on the brake, and 230 ohms resistance across them. With the lever in the run position, the voltage increases to ~65 VAC.
I read in another thread that loose/broken wires at the drum switch are common, but I don't see any issues there. The switch closes across 4 & 5 in the off position, so I don't think that this is the problem.
At the transformer, I'm getting 120VAC on 1 & 2, but zero volts across the two, instead of 230. I'm using a static phase converter. Could this be the cause of my troubles?
If anyone has any suggestions, I'd sure appreciate hearing them. Thanks.
