...I thought of even making something to blow air on the saw while sawing, anyone got some tips about this?
Dave,
I have known wax workers to attach tubing from a small aquarium
air pump to their saw frame to blow away wax shavings. I don’t
know if this would work for metal filings, but if you do a lot of
piercing, it may be worth a try.
Hope this helps.
