I have an old GMF 8" /200mm bench grinder. It's a 1978 vintage, used to belong to a family member.

I'm missing one of the flange washers for the disc.
Anyone know a good place to source one?

I'm also looking to ID the arbor thread size...
I've measured the shaft OD to 5/8" which is needed for the flange washer. The threads are slightly less than this, and have a metric 1.5 pitch, to the best of my knowledge using my thread gauge set.

Were these commonly 16mm x 1.5, or a 5/8"-18 tpi more commonly?
