I remember my dad playing with pulley ratios on the 1st table saw I remember him having when I was a kid, it was a '50s craftsman 8".
When I was in Jr high he bought a new craftsman 10" back around 1980-ish. I have had a couple of these over the years, I tend to buy one via CL when I have a need for one then sell it again, then buy another when I have something else going. They just take up too much space in between.
Most table saws I have experience with have had 1725 rpm motors.
I remember replacing a motor once in an old air compressor I had years ago. Originally a 1725 rpm 3 hp, I got a deal on a 5 hp 3450 motor
I thought it would get me better air volume.
Compressor was one of the original 2 stage vertical champion brand compressors from the 50s.
All it did was start get louder, hotter, and started pumping oil into the tank, (air discharge was always a mist of oily moisture after the motor swap) and the bits of (mostly sawdust) in the cooling fins on the outlet tubes started glowing red, like when a campfire is all but burnt out. It didn't do this with the original motor in place.
I don't know where it came from before I got it from an auction , but those fins were oily and dusty the whole time I had it. I tried at one time to clean up those cooling fins with aerosol carb cleaner (Gumout, etc) brake clean, and other stuff// but that oily residue did not want to let go. The 5 hp was ok, but the 2x RPM was a mistake.
At one point I measured the motor pulley and went up by 50% in diameter which split the difference in rpm between the original configuration and the speed of the compressor with the new motor which helped but not enough.
On a table saw isn't there a critical speed that the blades aren't supposed to exceed before bad things start happening to the blade, like on a grinding wheel?
