Scott,

That is rather horrifying if you have to regard it as "good news".
I wish you the best.

Does your doctor suggest any cause for the "de-mineralization" of the bone?
Is this similar to loss of bone density which leads to a lot of broken hips?

Not to disparrage your desire to protect from dust and epoxy vapors, but loss of calcium seems to probably have other causes in the majority of people.

The article on cyclone separators I offered will clearly show you why a large central system such as Bill suggests is better than a dust devil with a shop vac (however good).
The author of that article had lung issues rather than de-mineralization.

I wish you the best, and hope for your recovery to continue wood working.
