I have the same tension meter, I don't use it often but its nice to have as I use different blades and they all have different specifications. look forward to the next video.
Great video! I have the Starett version of this tool. They recommend a little preload on the gauge. So, after you set the fixed side, just move the variable side of the gauge to move the needle just a bit then lock down and zero out. Just FYI.
The Starrett can measure both directions, the lenox is only one direction. I have a Starett coming next week to verify that they are reading the same. I can try preloading the Lenox one as well.
Different manufacturers have different tensioning methods. Based on the mechanical advantages, each mill reads a different value on their tension gauge. For example, woodmizer runs around 3000 psi on their gauge where timberking reads 1100 psi. Each reads a different value, but in actuality, both are running around 17,000 psi of actual blade tension. A lot of folks say one brand or the other cuts better because they run a higher tension, but the blade is actually about the same.
The reading outcome of this type of instrument is going to be different based on blade width, steel type and thickness using a constant pressure gage reading, IE 1100lbs. It is measuring the stretch of the band. Measure a 1.25 x .045 vs a 1.25 x .055 and your gage reading will be different.
When comparing blade tension guages between sawmill makers, it is importage to consider the diameter of the hydraulic cylinder that is applying the pressure. If they are different sizes, but yield the same blade psi with your tension tool, then we know something else is causing the variance.
As long as you get a consistent tension and your mill works good then does it really matter if its 12,000 or 20,000?

My Starrett is one direction like the Lenox. So they must make both types. @@TCSawmills
Great info. Thanks. But how did y'all do at the craft fair?
I'm working on that video
Looking forward to adding more information and more testing ❤
Awesome video that's very interesting
Good info but what is the controversial part?

Ooooo, early bird special
Nice to know.
Don't need that high dollar gauge just clamp clipers on blade at 5 inch spread and stretch blade .002
Steel does not bounce back after stretching stress
Man for a very expensive mill the tensioning device and wheel shaft is cheap looking compared to say a woodmizer or even a Chinese mill
