I always wanted to measure the tension I put on my resaw blade (1.25" resaw king carbide blade). It's a relatively thin blade (0.024"). So tonight spent about 15 minutes to fabricate a very simple jig using a dial indicator to measure. At 12" of blade, depending how much I crank the tension wheel, I could measure around 0.010-0.013" of stretch. That translates to around 24100-31,400PSI which is around the range this blade should be.
When I ordered the blade I ordered a length in the middle of the range specified by the manufacturer. Next time I think will choose a little smaller blade (within the range).
