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.

.... 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.

Thanks for all the replies. So…..the tension stays the same regardless of the blade you’re using? I get the convenience of quicker blade changes but don’t I have to adjust the tension after installing a different sized blade? I’ve always tensioned based on feel flutter and sound so really don’t have a reference point. If not then I guess it’s handy to have but it only takes me a few turns to loosen it up to change blades. Plus it’s a retrofit so there’s always the risk of breaking something that currently works fine.

So, assuming it’s an easy install, do I have to adjust the tension anyway?

I read somewhere to tension a 1/4” blade to the 1/2” setting and so on. I do that and always detension after each use. That’s just me.

Different sized blades require different tension settings – that is why they are marked on the back of the saw on the tension adjustment. The tension release thing is to make it easier to tension/detension only – not to set the tension.

Brad

- Andybb

You will need to adjust the tension even when replacing with the same size blade. Even if it’s the same size AND same manufacturer :) You may get lucky and it’s just fine, or might just need a slight tweak, but it’s not a given. Just get in the habit of adjusting the tension every time you put on a new blade and you will be fine.

Brad

I think the tension relief levers, both aftermarket and factory included, are just another marketing idea. I stopped going to “Woodworking Shows” when I realized it was mostly snake oil salesmen with the newest, latest, greatest toy there ever could be, like tension release levers.
I did meet Mark Duginske at one, and I did learn about Forrest blades at one, so it wasn’t a total loss.

If you are using thin blades it probably does not matter, but if you are using wider blade under a lot of tension you should release some of the tension if you are not going to use the saw for a while.
A couple of years ago I was not able to to work in my shop for a few months, when I turned my bandsaw on for the first time in about 3 months the upper spindle assembly snapped. When I looked at the damage I noticed the upper spindle assembly was made out of cheap pot metal, the replacement assembly is made out of steel.
It probably will never happen again but I now release the tension after every use.

- GR8HUNTER

Don’t be confused. May I explain more fully. My second comment is about the EASE of changing the blade only. I still de-tension my 3/4” blade, on my 14”, after each use. My analogy is that NOT de-tensioning the blade after use, is much like not driving your vehicle for an extended time (especially in cold weather), Once you finally get around to driving that vehicle, you will find all those flat spots on your tires that developed, will bounce your auto around for several miles before they eventually recover from those flat spots. I find the same kind bounce if I leave my BS tensioned all the time.

Granted, I may not use my 14” BS for weeks at a time, but I can surely tell after a long sabbatical from the BS. I am sure some will disagree and profess their own wisdom, but so be it. This is what works for me and I find my BS runs smoother as a result.
