Nicely done! If you find the size a little to bulky, replace the Micro swith with a proximity switch. We used them on industrial lathes with great success.
Thanks Craig...I just spent some time looking at proximity switches...I used what I had on hand...it is not beautiful but here are some pictures of the very nice repeatability I got with that limit switch... www.machinistweb.com/forum/showthread.php?p=36732#post36732 Do you think a prox switch could do that as well?
Oh yes, most prox have a field effect distance, they differ based on manufacturer and size, so contact is not required. I was the maintenance foreman of CSX's Raceland Wheel Shop until it closed. We had two Hegenshent Wheel lathes, tracer lathes, that used barrel type proxs that triggered off adjustable dogs. The ten years I worked there we only needed to replace two of them. They were so durable that we had a hard time troubleshooting them because we refused to belive they failed. Limit switch would fail because the contact would eventually wear out the rollers or arms.
Great improvement. To bad you didn't show the finish on the shoulder I think a hard stop with a slip clutch will get you a better repeatability and you don't have to deal with any wiring. On the other hand a slip clutch will put some extra load and wear on the lathe.
Thanks...yea I should have shown that shoulder, but there are 2 pictures of it on the forum link...I think if I used the 1/4x20 hard stop on the holder instead of the limit switch...the shoulder would not be as good as the one created by the limit switch (I've used the hard stop a lot over the years)...I got a lot cleaner shoulder then I expected
