Cleaning gasket surface on 660 clone

[Windsorman]

Hi,

What's the best way to clean the case surfaces where the gaskets go? Those surfaces have oxidized a bit. Figured I'd clean them up carefully before assembling the saw. I've seen Matthew's method of using a die grinder with a scotchbrite wheel. Is that the best way? It seems a little aggressive but maybe it's the best way. I was thinking about running them across tempered glass with 1k paper. What about just using a green scotch brite pad freehand?

Thank you in advance for your advice,
Phil

If it isn't so bad that there's a hole eaten through it, I'd probably wipe off whatever is loose on the surface, and let the gasket or gasket maker do it's job. If the case halves are apart, then go ahead and use either scotch bright or a flap of fine grit (400) sand paper on a dremel. Maybe even a soft bristled brass brush rotary bit, the cone shaped ones are not as aggressive as the flat disk ones.

Great advice! Thank you.

I'd opt for the plate of glass and some wet sanding. Just my opinion, but better to spend a little extra time and know the mating surfaces are flat and clean before assembly.

I often use very fine sand paper or scotch brite by hand, depending on how much stuff needs to be removed.

I like to assemble the case halves, with the gasket, dry. When I do a base gasket delete on the cylinder I of course use a sealer.

I use a piece of scrap countertop granite with 5" self-stick sanding disc stuck to it. Run it over the paper in a figure 8 pattern.

I just scrape the stuff off with a razor blade. Then wipe with acetone to remove anything left. Oil or whatnot.
