These are things I have been with my 4x6
1. Bimetal blade is the most important. They are expensive but worth
it. They are usually 10 teeth per inch that alternate with 14 teeth
per inch. It sets up a clearing action that carries away chips and
faster cutting.
2. I do wax the blade with paraffin or if I run out, the old paste
floor wax. Helps a little, not a lot.
3. Because the stand is so wobbley, I cut sections of angle iron and
bolted them between the legs to stiffen the whole set up.
4. I do use coolant-plain water. I looked at a lot of synthetic
coolants and too polluting for me to poor out on ground or flush. I
got a big plastic bucket for below machine and put in one of the HF
pumps for rock fountains, on sale for around $10.00 as I recall, but
usually 14.00. I fixed the tube to drip just above the blade. With
this set up, I cut a 3 inch solid steel round bar in not quite an
hour. Previously, it took days, I would start at the first of week
and use cutting oil, squirting it on at intervals, would go a couple
of hours, then turn off, then restart next night, until finally cut.
What is impressive is how the water may cool the blade but it
carries alway all the fine chips that retard cutting. Therefore, to
protect the pump from fine chips getting into the intake, I cover the
pump in the plastic bucket with an old plastic orange juice bottle
cut out to cover the pump like a hat.
5. If not using water coolant, I do use weights like the hammer
descirbed to add force to the saw cutting.
