John--
Sorry to hear about your father's suffering.

For working wet in your garage, Ken Barnes'
recent post sounds right on; add a sump,
recirculating water system with a couple of
silt settling drums, and a curtain. My only
suggestion for possible change is that instead
of the strip curtains Ken mentions, which I
found to be rather expensive, I simply hung
vinyl shower curtains (with plastic extensions
sewn on the bottom to make taller) off of a
rail made from 1/2" or 3/4" galvanized electric
conduit. I bent the conduit with a pipe bender
to give rounded corners and joined with
screw-type conduit "unions," then hung the
whole mess from above. I also put a lid on
mine, but not sure it's necessary with wet
cutting.

For other details on my working methods with
water, especially how to get the water to the
tool, see my post from Dec. 17 2002.

I will mention again that in spite of the wet
techniques I still wear my N-100 respirator
whenever I'm in the studio. It's possible some
of the wet techniques leave a very fine mist,
with stone particles inside, suspended for a
while in the room. Also, sludge dries on the
walls and curtains and could be remobilized.

Happy wet carving. You'll wonder how you ever
lived without it.
