A spot of mother of pearl inlaying.

[the great waldo]

Hi Wal

I would imagine wetting the pearl would keep the dust down and possibly increase the life of the cutters. I've been making guitars for 40 years and in the old days I used to grind abalone shells dry with a grizzly disk on a black and decker drill, Mixed up with a nice dose of nitro cellulose i'll be glad if I make my pension. Luckily I don't smoke LOL I don~t think it matters much where you put the filter but higher up would capture more airborne dust or put the filter by the where your'e cutting maybe with a small computer fan blowing towards the filter or just get one of those cheapo 4 inch kitchen ventilators with the flexi hose that comes with it and run it outside. I use uhu blue epoxy for pearl mixed with a little polyester colouring paste and some fine ebony or whatever wood you are using dust (the dust (not too fine) stops any filler becoming to shiny if the fingerboard is polished)

Cheers
