I hit the jackpot on control pin Clausing 5913 lathe

[ltlvt]

It helps when I do my homework. Before I came in from the shop this morning (around 1:30 AM) I measured the length of the control pin for my Apron . The total length of the one I have is 1.060 inches total length. I called Clausing tech support today and was going to just buy the pin and spring from them but they no longer sell either. When I told the tech support man the length of my pin he said Yep its is too short. it should be 1.156 inches. Just .096 longer but that is about the depth of the slot. He emailed me both prints. The control pin and the spring. I am including the drawings for future reference in case anyone needs them.

Is LEDLOY 300 the same as 12L14 free machining steel" I was thinking of making it out of a socket head cap screw. Anyway, here are the drawings.

A socket head cap screw is hardened and tempered alloy steel. Not very friendly to machine.

I would use some 1045, or machine down a large grade 5 bolt to make a mid carbon steel cylinder. Then make your copy. For heat treat just use a plumbing torch and a bucket of water to harden and temper the tip only, as it is the only part being impacted.

I've made parts out of socket head screws in the past without too much difficulty; you might want the toughness for a high-wear part

I think most socket head screws are similar to grade 8 bolts, and can be machined using carbide without too much trouble.

The generic black oxide SHCS are a little stronger and harder then a grade 8 bolt. Never said they were impossible to work with. Just saying that 1045 is easier to work with, and if heat treated well is even harder than any generic of the shelf bolt.

same here. I have no problem turning a socket head screw.

I would use 1144 stressproof. I like it for a lot of things. Easy to machine, hard enough usually.
