[Hahndorf1874]

I found a Stihl chainsaw raker file is great for this application,fine cut,also has safe edges as well.

A simple "jig" for this an be made up from 1/4 X 2 flat stock about 6" long.

Drill a flat bottomed hole along one edge to the depth you want the rim thickens slightly larger in dia. this leaves a recess for the rim to sit in.
Bolt to drill press table with the hole aligned with spindle.
Lower rim into recess. lock spindle
lightly lay file on pads and slowly push forward. When the file stops cutting your to thickness.

Thanks, country. Trying this. If it all works out I’ll put up an informative post.
