Wow Roger, we have a lot to talk about today, both on and off the list.

First clean the heads with solvent. Probably don't need a wire wheel
but if there's a lot of grease it would be worth it.

Then use a small round metal burr on a dremel to do the same thing a
dentist does and get the decay out of the holes.

Mix JB weld and fill the holes. Don't necessarily try with one pass,
it takes less time to do a pass at filling than to remove overfill.

Get a can of spray glue and glue some 50 grit sandpaper to a piece of
3/4 ply or other similar flat surface. Best if you can use waterproof
sandpaper. screw a one by two to the back of the board and lock that
up in a workmate or similar. Flood the sandpaper with water and scrub
the head (flat side down, of course) on the sandpaper until the JB
weld is flush with the head. Rinse, repeat. You can easily tell the
difference in color of the sanded JB and that which hasn't quite been
built up to the surface. I can send you picture is you like, assuming
I can find them.

Jim
