I use power sanding for bowls but I've been wet sanding platters and enjoying the absence of dust. I've been oiling the platter and soaking the sandpaper in walnut oil. It makes a nice slurry and works quickly but walnut oil does get mixed up in the wood chips around the lathe.
i realize walnut oil is flamable but do I need to worry about spontaneous combustion the way I would with some other oil finishes?
