How To Use a Lenox Bandsaw Blade Tension Gauge

[@hootinouts]

Excellent presentation sir. Everything explained in perfect detail. I am a DIY mechanic/hobbyist and own a small metal-cutting band saw that has served me well over 30 years; except, I am always breaking blades. I have always guessed at blade tension and realize this is the culprit to blade breakage. I cannot justify purchasing a Starrett or Lenox gauge, but it is obvious enough how they work, so I intend to make my own. I am a mechanical designer and a machinist so that should be no problem. I will incorporate a .001" dial indicator and tension my blades to the calculated stretch in thousandths.

Great little tutorial. The one thing I would add though, is to make sure when installing the gauge that you do not seat the back of the blade so as to touch the back of the gauge. Ensure only the set screws are in contact with the blade, not the gauge body itself.

I agree. otherwise the jaw that pivots might bind, thus giving a false reading.

Thanks for the very clear and helpful explanation.

Good information. Thanks.

Very good thanks

Would it be advisable to preload the gauge just a bit, then set the dial to 0? That way you know the bottom pivoting arm is against the gage.

I don't think you would want to do that. Just slacken your blade until it is completely detensioned, but don't let the blade curve or get floppy. Then mount the guide and zero the indicator. You are possibly correct that a tiny bit of preload wouldn't matter. But I prefer to start with the blade slack but straight

What is the recommended tension for cutting wood (woodworking)?

typically between 15k and 22k PSI but look up the specs from the manufacturer. they're not all the same
