I have a very old craftsman table saw that I restored and enhanced with dust capture and a few extensions. It has a great cast iron table and for an old workhorse saw I actually really like it. Recently I have been doing a fair amount of rip sawing of long pieces. The wood was donated to me in big chunks and ranges from cypress to Florida hardwoods like Rosewood, Mahogany and Sea Grape.
My issue is that my rip blade starts vibrating badly once I get a little ways into the wood. This is causing lots of problems. I am getting everything from wood burns to having the extra drag on the motor trip the breakers on a regular basis. As the blade vibrates it is taking some 1/8th inch (roughly) chunks out of the wood on each side. It just isn’t fun.
These problems are happening on everything from soft pine to the hardwoods. I am taking the cuts very slow and not burying the blade too deep. I have even seen similar symptoms on 1 inch pine boards.
The blade is in good condition and when the machine is off I can’t feel any slop in the blade when I try to move it around by hand.
Does anyone have any thoughts on what could be causing this? I could really use some suggestions about what I can do to get this machine back in good working shape.
I have considered buying some link belts, but it doesn’t seem like the belts are where the vibration is coming from.
Thanks for your help
