Just finished rebuilding my 18" bandsaw, replaced bearings and tires(rubber to urethene). The blades are too long as the result of all this - had one shortened twice. The tension gauge is now MORE of a relative indicator. I'm using a 1" 2 tpi blade and the tension indicator is greater than 1 1/2". Here is my problem. I resawed a piece of birch and the difference in thickness was less than 1/16" between the 4 corners of the board. Three corners were the same, the bottom, last thru the blade was less. I thought it was good to go. I then tried a piece of qtr sawed white oak. The difference was 3/16", the bottom, last thru being the offender. The top was straight cut and there was also some cupping from the blade. So, my question is do I need more tension or should I get another blade? The blade was new and I tried to keep a slow steady feed rate for both pieces. I can't adjust the tension any further, which might mean the blade is still too long - original 141 1/4" and now at 140 1/2 "
