Is this a "new" issue, or has it always done this? Is it a new blade that does it or will any blade walk off?
Have you cleaned the tires with a stiff brush while it's turned on...Yeah I know it's dangerous. You can remove the blade and just do the bottom wheel under power. Are the tires "crowned" or dead flat. They should have a slight crown.
When you back out all the guides away from the blade that's centered on the tires, what happens when it's running?
Remove the table and check the rims of the wheels with a long straight edge to see what's going on. Is one of the wheels loose in it's bearings?
Is the tension spring too compressed/blade too tight? OR is it not compressed and the blade is too loose?
How's that for a list of questions? :laughing: bill
Let me see if I can answer all of these....
Is this a "new" issue, or has it always done this?
Because of the weather here, the saw sits for most of the year with the tension off the blade. Its just too darn hot to be out in the direct sun in a super hot shed most of the time. I bought the saw last November and it worked fine all winter. When I tried to use it this year for some resawing, the 1/2" resaw blade came completely off the tires and nothing I did would keep it on. Blade was a 1/2" Wood Slicer resaw blade.
Have you cleaned the tires with a stiff brush while it's turned on
Ah, not while its running, no. However there is a stiff brush that is in constant contact with the lower tire. I'll try brushing the upper tire and see if that helps.
Are the tires "crowned"? Yes.
When you back out all the guides away from the blade that's centered on the tires, what happens when it's running?
Haven't tried that except to turn the wheels by hand. Hand turning of the wheels shows no travel. I'll try it with the motor running and see what happens.
Remove the table and check the rims of the wheels with a long straight edge to see what's going on. Is one of the wheels loose in it's bearings?
Wheels appear to be tight on the axles with no bearing lash. Also appear to be properly aligned. Again, I'll recheck.
Is the tension spring too compressed/blade too tight? OR is it not compressed and the blade is too loose?
Compression spring seems to be working properly. I use the "pluck" test when tensioning the blade and do not rely on the indicator. (I paid close attention to the demonstration given by the guy from Carter at the wood show and watched his video several times.)

Sheesh.. I thought this was a woodworking forum, not a police interrogation.... :laughing:
