My main interest is restoring vintage watches and the restoration of the case has always been a story by it self.
Buffing out scratches is "easy" but you often end up with a case that has rounded corners and in worst case - a watch with a somewhat deformed case.
I also used different methods for getting the brushed surface back om cases and the worst one - the sun burst was made using a simple jigg - alot of patience and time!
As a mechanical engineer I love machines, and it was time to get a new one for the work shop.
My first go was using a disc sander as base and building a fixture for it.
I made an order for some goodies.....
A 12" disc sander with a cast iron base and tiltable table
Hooking it up I noticed that the disc was not spinning as I wanted - time to measure the "wobble"!
0.25mm difference along the edge of the disc - not good!
Getting the disc lose was a mission in it self - but with a homemade "puller" I finally got it off!
Got it set up in my lathe (had to cut it down to 10" as this is the maximum diameter my lathe can handle) and got the surface within acceptable values.
