Hello All,
I've just noticed an odd little problem I seem to be having when cross cutting on my table saw. I was trying to fine tune the alignment of my mitre gauge (Incra 5000 converted to a 3000). I now think I've got the gauge squared up overall, but I'm noticing that my cuts on boards of any significant width, say 5-6 inches or wider have a slight concave curve to them on the workpiece to the left of the blade (probably less than 1/64th of an inch but pronounced enough that I can see it with my naked eye when I stand the board on end on my table saw table). I've attached (I hope I've done it correctly) a pdf file illustrating the problem/result I'm experiencing.
I'm wondering if this could mean I have the blade overtightened on the arbour causing the blade to be slightly bowed or flexed? Is this even possible? I've always tried not to overtighten my blades as I understand that the thread is oriented such that the blade/arbour nut will tend to tighten on its own while spinning in use. Any other ideas why/how my table saw could be cutting a curved crosscut? I don't think I've ever seen this happen before. At least I've never noticed it until today. By the way, the saw is a relatively new (9-10 months old, lightly used) Steel City 35905G 3hp granite top saw.
If anyone has any suggestions as to the cause of this I'd be most grateful to hear your ideas.
Thanks a lot!
