Unimat - taper pins

[Johnwa]

I need to turn a couple of taper pins for shear pins. The pins are about 1.25” long with a taper of ¼”/ft. On a unimat you can rotate the headstock to cut a taper. Here’s a couple of pics cutting one in steel. The actual shear pins will be brass. The scarf comes off looking like steel wool.

Why do I have this feeling the next time we see a picture of Little Greeny, you will have overclocked it with micro-VFD, stepper motors on all the lead screws... and motion control under the headstock so it can power rotate too for good measure!

How do you get the headstock exactly straight after John?

There’s a locating dowel pin in the front of the headstock. You can see the hole for it in the picture.
