later Whilst I was able to get one blade to work I found that the other had a misaligned weld which caused a wine barrel ring effect and prevented it from stabilizing on the bandsaw wheels. For an unparalleled blade, no alignment setting can be corrected. Also with new modified tires. With particularly strong tension, a blade began to cut normally. However, when cutting meat, fat due to grease adds just enough lubricity for a blade to slip without perfect precision and alignment. My old blades work fine, I just wanted something sharper.
