I picked up a used Hunter BL505 Brake lathe from a local service center. While it seems easy to use, I found something that doesn't seem quite right. It has a limit switch on the caliper feed that will shut the machine off when it gets to the end of a cut. makes perfect sense if you are making a cut & leave it unattended. However the machine does not shut off when it hits the limit on the drum feed. It binds up & I am afraid it will wreck something. There is a switch there that prevents the caliper feed from running if the drum is not in all the way, but I would think this switch would also stop the drum feed from jamming up?

Hope I am explaining this correctly. I am thinking someone might have mis-wired one of the cherry switches on the main control? But I can't find a wiring diagram. There are 5 cherry switches in the machine & all of them test good, so I am puzzled.

this is a picture of the same machine for reference.

Most have a adjustable arm that "trips" the feed,so it will stop feeding but still spins. See if it's note here; http://www.hunter.com/brake-lathes/bl500-series

Thank you, I should have posted back earlier. I took the thing apart & realized the limit switch is only to prevent the movement for cutting rotors to active if the drum cut is out at all. The stop on the disk cut is pretty much like you said. It goes to the end, hits a sling & then will run out of threads & just "click" Seeing it had an electric shut off on the movement the other way, I was assuming it shut off electrically the other way too. Assuming got me in trouble.....

Thanks for the reply!
