I am thinking of buying a different table saw as the old Ryobi BT3100 literally isn’t cutting it any more. I think it definately lacks in power amongst other things. Based upon the voltage and amps it seems to be about a 1.50 hp universal motor. I got this by taking volts (120) times amps (15) multiplied by a motor efficiency of about 60% then divide that by 746 watts, which is 1 hp. The saw is also rated at 4,800 rpm’s. It starts to labor while cutting 5/4 cherry.
I have read all the table saw reviews on this site and others several times over and people with contractor or hybrid saws with induction motor ratings of 1.50 to 2.0 hp seem to say that these saws have plenty of power. Most of these saws seems to have a rpm rating of about +/- 3,450.
My question is this- Since I have about a 1.50 hp saw now, would see a big difference in the ability to cut thicker stock if I were to obtain a saw with a 1.50-2.00 hp induction motor? I am guessing that I would some improvement, exactly how much I don’t know. My reasoning for thinkng this was is that slower blade speed equals more torque to the blade. But I am not sure. Just trying to find out if 1.50 to 2.00 hp motors will be enough for my needs.
Since I like old stuff, the ideal saw would be an old unisaw from the 50,60, or 70’s and fix it up, but unfortunately 3 hp cabinet saws of any age don’t show up in the online or paper classifieds very often. And I can’t go buy a new Griz 1023 since my wife already complains about the hobby. I am trying to broaden my chances of obtaining a used quality saw that will last many years and meet my weekend project needs- mission type household furniture, etc.
Any information would be greatly be greatly appreciated.
