I currently am using a Gts1031 table saw for my onsite work and was wondering if anyone could lend some ideas on how to add a soft start to the saw? I looked around and heard of people using variable speed controllers from router systems to achieve some sort of slower start up. If possible, wiring one into the switch would be ideal. Can this be done? Are there other options? I cringe every time I turn the saw on! Thanks!

If you are scared of the table saw when it starts then I would stay away from it. soft start or not it still has to spin up to full speed to use it, so what’s the point.

Thanks for commenting. It has nothing to do with being scared but, rather the entire saw moves and shakes when turning it on and how it gets to full speed, thats the issue. Just as we all appreciate a saw passing the nickel test when turning it on, I realize this isn’t realistic for a direct drive benchtop style saw to do but I would like some resemblance of a smooth start. Just trying to make it a bit more user friendly. I understand that the 4100 series has a soft start and was wondering if anyone understands the inner workings of it that I could incorporate into the 1031 through some mods.

Did you get anywhere with this, because I am interested in this as well.

For this to work, it would have to be a universal motor (uses brushes)—which it probably is. But something is wrong if you are getting that much vibration and shaking. Could be a bent shaft, bad bearings, or warped blade.

I had a Craftsman jobsite saw that showed visible blade wobble at startup and shut down, and would jump around and vibrate. Once up to speed, the blade ran true, but as soon as I would make a cut the blade would slow down, and the wobble would reappear. No way to make a clean, true cut on that piece of junk. The kerf was always wider than the blade thickness.

I never did get a fix…ended up letting my father borrow it and he burned the motor out on it!

Have your say...
