Turning Large Diameter, Short Length Material

[tq60]

Do your jaws open enough to grab it?

If so grab it and center it.

If not open jaws wide as safe.

Put 2 layers of electrical tape on the face of each jaw and with a live center in tail stock inserted into the threaded hole push it the disk against the chuck.

It may take some good torque on the tail stock but it will hold it.

Start with low speed and make sure disk stays put, if not increase a bit.

Increase speed so you get some flywheel effect.

Very sharp bit with very light cut.

Very light,0.001 for starters.

Place the good side against the chuck.

If no good side then face first then make round.

Flip over and face.

Use power feed at slowest setting for consistent cut.

Haven't posted an update because I fried my motor. Spent 3 days hoping something would turn up on Craigslist or FB Marketplace. Not even a trashed but working old Craftsman 10" table saw to rip the motor off that was worth a drive. I have a RPC so ordered a 3ph 1/2 hp that arrived today broken. 2d motor has been ordered, since I had to reorder, spent another $12 for a 3/4 hp. Hopefully this one will arrive intact.

To cut to the chase, please see below. Very light cut ( a weakness with the Logan 10" is when the crossslide is backed all the way out the micrometer is coveted). Along with the new motor, I also installed the correct pulley so the rpms are as designed. This cut was in BG @ 63 rpm. Lathe was still set up for metric threading, 1.5 thread. No slippage detected.
