Find the center of your disk. Measure the diameter of the outer rim of your faceplate. Divide by 2 to get the radius. Set your compass to just a hair over the radius and draw a circle on your disk. Now, get some double sided sticky tape and mount your faceplate so that the radius is even all the way around. Use a vix bit or something similar to pre-drill your holes for your faceplate. Dismount the faceplate, remove the tape, and remount with screws.

I've been wanting to turn my lathe into a disk sander for a while.
So I bought a 10" disk that is designed to be used on a table saw to turn it into a disk sander.
My question now is how can I mount it to a 1" x 8 tpi faceplate?
I want it to be very close to perfectly centered.
Any ideas?
If I could figure out a way to get it centered I'd probably epoxy it in place. Maybe even drill and tap a few machine screws while leaving the face of the disk flush.
Any thoughts or advice are appreciated.
Seems to me you want a 1" x 8 tpi to 5/8 arbor adapter. Though, I have no clue where to find one.
Otherwise, I'd buy a large diameter faceplate and face with an MDF disk that is trued after mounting.

There's a centered hole in the sanding plate. Glue a thin piece of wood to your faceplate, turn the edges off, leaving the center proud, and of the diameter of the hole in the sanding plate. Center and glue.

Metal spinning technique. Faceplate in the headstock. Piece of wood in the tailstock. Sanding plate between the two. Once centered drill and tap some screws to hold it.

I took a 3/4" piece of plywood and attached a 5" face plate to it. I made it slightly larger than 10" so I could true it up on the lathe. You can buy various grits of 10" paper with a sticky back from Lee Valley. Works great.

When I did my 16" aluminum disc I put the disc in my large Cole jaws, marked it and it turned out very well. Good luck. Tony
