Today a little something about the basic of reluming: the sandwich dial, and a few tips to make it glow brigther. This is the perfect job
if you're begining, because you can't really screw up
A sandwich dial is a two-plate dial, the first plate being coated with luminous material and the second plate pierced through for the indexes
and numerals. So the first step is to separate out these 2 plates using a sharp blade.
Please be carefull never to manipulate a dial with your naked fingers.
Store the top place in a safe place and fix the back plate on a stand. Here is mine it's, flat, made out of plastic, and there are 2 holes for
the dial's feet. The dial needs to stay perfectly flat so it doesn't bend.
It's now time to remove the old lume and the glue from the backplate. The best thing would have been a sandblaster, but as I don't own one,
the next best thing is a ss brush on a dremel
The plate might heat when using the ss brush. If it starts heating too much, just stop and wait untill it's cool again.
Bench grinder with circular ss brush to make the finish uniform.
Now a quick polishing to be sure the finish really is uniform.
