I very much like my 14" 3/4hp Delta bandsaw with riser block installed. Everything was hunkey-dorey until I installed a 3/4" blade to do some heavy sawing of some thick walnut.
Adjusting the blade so it tracked in the middle of the top wheel causes it to rub on the bottom end of the blade guard between the upper and lower wheel assemblies. This blade guard is an extension furnished with the riser block.
To track the blade to where it doesn't rub, the teeth have to be almost flush with the outside (side nearest the door) and even then there's a slight rub.
Checking the bottom wheel once I got rid of the scraping sound I see the blade is almost in the center of the wheel where (I assume) it's supposed to be. This leads me to believe that the two wheels' faces are not lying in the same plane. (??)
I'm considering placing a thin strip of shim stock under the far side of the riser block thus kicking the top wheel forward, then using the tracking adjustment to bring it back parallel to the bottom wheel. It shouldn't take more than a few thou to do this and would bring the blade out away from the back edge of the blade guard.
Before I look up my hernia brace dealing with the weight of that upper casting and all, does this sound like a reasonable thing to do or should I live with the blade riding so far off center of the top wheel?
