JUst finished refacing the green disk mounted on the outboard end of an old lathe with 80 grit I use a heavy squared block of hardwood and a mandrel inserted at exact right angles all round against a mitre block set up to the same specs. I use the same block for both sanders this one happens to be 14 inches and I had it for donkey years.
The red disk I had for maybe two years new at the other end of the shed not used so I flattened the disk aluminium by hand on a glass sheet with sandpaper and fitted a velcro base then a 120 grit paper disk. I use the same block with the both sanders and mounted a table on the bed of the lathe. It took me hours to remake the mitre part using a brass flat for the slide milled to a neat fit on my Mill made a swivel pin tapped into the flat then a locking Allen Headed screw to keep the right angle to the disk. The mitre came from an old 10 inch saw I had once.
What looks like a great overkill is not to me as I control the process and it gives me the accuracy I want. I had another 12 inch disk gave the unit to my mate who made a Fairground Organ at his home and my 21 inch unit to another mate who installs flooring in my downsizing attempts.
