Im stripping a Buffalo Forge Co. #18 drill press in preparation for
making Mucho Macho Drill Press #1
(1hp, MT3 spindle, VFD)
Ive used StripEez paint stripper, but some of the old filler will not
come up easily in the corners and crannies. Ive cup brushed where I
could, and still cant get into some of the tight places. The biggest
media I have for the blast cabinet is 40-70 crushed glass and its
taking forever to remove the paint/filler
Will I have better luck with sand?
I would avoid using sand for a number of reasons, silicosis being an
important one. Besides, sand is not particularly aggressive IMO.
I'd be tempted to try "Black Magnum":

I've never used Black Magnum, but I've been curious about it ever since I
first saw an Ebay listing for the stuff a while back: it looks like good
stuff.
Here is a description of Black Magnum from another distributor's web site:
Quote:
Coal Slag product that is very angular and contains less than 1% free
silica. Black Magnum is available in coarse to extra fine sizes. The
hardness of this material makes it very resistant to material breakdown.
Advantages:
- Does not react with coatings so there is less coating failure
- Does not draw moisture
- After-job cleanup is fast and easy
- Low free silica content

The only reason I haven't bought some yet is because I bought a fairly large
supply of aluminum oxide before I came across the Black Magnum listing.
If you get some of this, let us know how you like it.
