I know that this has probably been beaten to death earlier, but has anyone
rigged the Harbor Freight coolant system
up to
one of our saws? I'm looking at doing a lot of steel cutting, and it struck
me as a good choice.

Cooling:
When I looked at cutting oils, they all seemed fairly toxic for me to
put down a drain at home. Therefore, what I did was get one those
cheap HF garden pumps, some clear tubing and a large plastic pan that
was wide enough to fit below the saw. I use the set up to cut 3 1/2
inch solid steel directing dripping water onto the saw blade and just
recirculate the water. I put the pump itself in an inverted plastic
bottle with the bottom and side hole cutouts to prevent the fine chips
getting into the pump intake. To my amasement, it decreased cutting
time from literally hours to about 45 minutes. What I saw the water do
was constantly wash away or clear the fine chips from cutting. I then
realized what I was doing beforehand, was cutting over and over the
same fine chips and no wonder it took so long. Others to help prevent
rust, add TSP to the water. What I do is just clean up and dry
everything afterwards. A little oil would also, likely help.

I asked about that once earlier. never got around to trying it, cuz
i don't cut alot of steel.

I think you may be right about the toxicity. Perhaps
rec.crafts.machining might have some interesting info on cutting
oils, I'll have to check.
