Just curious if a blade tensioner is really a worth while addition in practical use. I have always just pushed the start button and go. Am I really ruining my blade?

Never felt the need for one… use the scale on the back to get it in the ball park, then pluck the blade until it sounds right :)

Changed the title just to make sure of the question. I’m referring to the tension release bars/systems that can be installed to relieve tension when the saw is not in use.

Ahhh… that’s a different beastie :)

This question comes up from time to time. The general response seems to be – most people who don’t have the tension release typically don’t de-tension the blades… those that do have one do (when they remember to do so). I personally never de-tension except when changing blades.

Sorry for the poor choice of title to start.

Brad, if it’s good enough for you then I’m good with it. I would never consider de-tensioning by just turning the knob between uses. Too hard and stressful getting it to some nebulous tension that my little brain is ok with.

A buddy of mine got a new tension release for his Griz and said I could have his original one. He seemed almost insulted when I told him I would pass. Just seems like a lot of work and potential to break something that’s not broken now. Not sure that Mr. Snodgrass would approve but…... :-)

The only reason for a tension release as I see it is to make changing a blade quicker. I have never had a tension release. My bandsaw is a 14” Walker Turner cast iron monster built around WW-2 era. I bought it around 1961 and in all of those 58 years I have kept the tension on my bandsaw except to change or re-mount the blade. No problems in that 58 years regarding keeping the tension on..

I have one on my Powermatic and I like it because it relieves the constant pressure on the bandsaw tires. This will extend their life and not cause indentations in them from constant pressure. Still using the original tires.
It also makes blade changes easier and this is a plus+ for me. I just fine -tume the blade pressure with the knob after changing blades.

I use the tension release on my 14’ Rikon BS because I use a 3/4” resaw blade. Why weaken the tension spring between uses because you are being lazy? Just a thought…

I replaced my annoying knob with a crank, and now it’s super easy to tension and de-tension the band saw. If I had a saw that had a tensioning lever I’m sure I’d use it, but the crank is a good in-between solution.

Thanks Tony. Why do you say that??

But…..the real gem in your reply is the Aristotle tag line. That is a keeper! Just texted it to my 3 adult children.

.... and if I could answer your question to him …. why?, my answer would be “about forty five years of never having a problem on saws as small as 10” and as big as 42”.
I currently have an 18” Delta with a tension release. I only use it when I change blades.

Damn Paul….I’ve only got 35 years of never having a problem with band saws 14” to 36”. I’m still a pup!

Andy
Just personal experience.
The newest band saw in the shop is a 14” Delta?Portercable? (don’t remember, same difference) It’s at least 10-12 years old, The oldest is the 36” No idea the name or year, but it’s a beast…gotta be 60-70 years old. Two others in the shop that don’t get used very often, maybe once a week…probably 15-20 years old.
All are left under full tension 365, No issues.
Another old one is the 15” General I got from an uncle used, when I was 15? It still sits in my mothers garage today,it’s probably 40 years old, under full tension for 40 years. It gets used maybe once a year?.....I’ve never had a problem with any of the above due to full tension stress’s. Blades, tires, frames, or springs.
Just my experience.
Does shit happen? Sure it does….but usually just on the internet.

I don’t detention my PM 14” with a 1/4” blade, stresses are too low to worry about.
My MM16” with the 1-1/4” resaw blade gets detensioned, I just don’t like the multi-tons of force applied to the bearings while everything sits idle. Beyond that, no real reason to if your blade is not tensioned to the upper limits of your saws capacity.
