I'm getting burning (actually the wood is burning) when making cuts on my Delta contractor's saw when the blade is tilted. I've read the posts (Preston and others) and Delta's procedure for taking a flat board and ensuring the trunion rods are in the same plane. I used a piece of MDF and they appear perfect, that is, until I tilt the saw at which time the bars are no longer parallel. The weight of the motor is skewing them.
I've aligned the blade to the miter slots when the blade is vertical and that works fine. If this was minor, I could adjust the fence a litte but the back of the blade pinches by about a 1/16 which is not safe.
In Ian Kirby's book on table saws he pretty much says this is a design flaw and to leave the blade at vertical and use jibs.
