I've always used a 3/8" blade and I've adjusted the tension accordingly. The blade ran true and my cuts are fine.
Some months ago I bought 1/2" and 3/4" blades. Today I tried the 1/2" bla de on some 2" hickory, adjusting the tension as I would the 3/8" blade. T he 1/2" blade seemed to wobble laterally, a bit.... certainly not the same smooth running as the 3/8" blade. I'm supposing this 1/2" blade needs mo re tension. My cut time for each board is about 2 minutes, max, so I don' t think the extra tension would affect the bandsaw tires. The tires are n ew and the blade runs true/center on the wheels.
Is my assumption of not enough tension, on this 1/2" blade, the probable ca use of the lateral wobble of the blade while in use?
