cgallery - this thread seems to have died the death, but I'd like to ask if you ever resolved your problem, or what you eventually did. I have exactly the same issue - also primarily with a table saw. My previous (low cost) table saw had gear teeth cut into the motor shaft (1/2" diameter), which meshed with a 2" diameter gear wheel on the saw arbour, and after a couple of years of very little use, it stripped all the teeth off the 2" gear. I have bought another saw table, again low cost, though adequate for my needs - but it suffers exactly the same problem - the saw blade comes up to speed in what seems like about a mirosecond. I'm sure a soft-start of some kind would greatly extend its life. I'd really prefer to build something rather than buy an off-the-shelf solution, and I have a couple ideas (one triac-based, one IGBT-based), but I foresee problems with them both. How did you get around it?
