Can I really resurrect a thread several decades old? That's a miracle!

Anyhow, my theory is that a blade will always track to the high side because more pressure on the high side of the blade bends it ever so slightly on that side and steers it back to the top. Belt sanders and band saws work on this principle with crowned tires. Mathias explains it well he

So what about flat wheels? My bet is that the wheels are towed in compared with each other. It is only very slight, but it keeps the blade tracking to the rear of the wheel and in contact with the blade guides. If someone wants to verify that their Walker Turner has co-planer wheels or slightly tow in.

That's my .02 for a thread from 1997.

You might be on to something but a blade will track towards the part of
the wheel that provides more friction/traction, typically the high spot.

If you drive your car parallel against a curb the tire will naturally
try to climb the curb. I think this is a similar principal with the blade.
