Poka-Yoke for Bandsaw
I don't usually release the tension on my bandsaw because I use it every day. But, we were discussing it at our guild meeting and I went home and flipped the lever to release the tension. A couple days ago I was cutting a 12" high piece in the bandsaw and the blade jumped back along side the back bearing and it had never done that before. It did that because I forgot to flip up the tension lever. I cut some thin stock the day before and it cut a little funky but I never gave it any more thought.
So I made these little Poka-Yoke ( mistake proofing) discs to remind me to tension the blade. They are 3/8" plywood and have a rare earth magnet in the back. I'll stick it on the lever after doing the tensioning. I made an extra one for Bruce who has the same model Grizzly bandsaw. Besides it gave me another reason to get on the laser today!!
Cheers, Jim

Ryan/// ~sigh~ I blew up another bowl. Moke told me "I made the inside bigger than the outside".
good idea jim. but im the same, i never release the tension ! ive never had a problem not doing it !
working with my hands is a joy,it gives me a sense of fulfillment,somthing so many seek and so few find.-SAM MALOOF.
I knew a guy who always de-tensioned, and he also made his own throat plates. When new he would use a sharpie to write TENSION on each of them so he was looking down at it when he was setting up his cuts. Seemed to work for him. I have tension arms on both of mine, but never use them. If I could swap them I'd have brakes on mine.
I'd never seen, or heard the term Poka-Yoke. I searched it, and evidently I've lived a sheltered life. :-) Looking further I see it's, Poka-yoke (poh-kah yoh-keh) is a tool used in Lean and Six Sigma tooling. manufacturing term.

I just recently bought a Harvey BS and never had a saw with a tensioner. I took a piece of cloth (about the size of a washcloth and covered the power switch and held it there with a magnet. I needed to move the cloth to the side to hit the switch. That was my way of remembering to set the tension. Then I realized I've owned a bandsaw for over 25 years and never detensioned it. The only time I touch it is to change the blade. Now the rag reminds me to turn on the dust collection. 🤪

Thanks Ryan and Larry!!
Hi George. I don't know how many time I'll let the tension down, but now I have a warning sign to use before using it that way. I was in Quality Assurance and set up a lot of Poka-yoke methods to prevent mistakes. People just naturally forget- especially us old folks.
Hi John...did you get the Harvey Alpha. That looks like a great saw !!
Hi Tony. I am loving the laser. I got my first paying job for it last night. I'm just waiting for the wording they want!.
Cheers, Jim

For the reminder sign to work for me, I would have to attach it to the blade for it to do any good. I typically do not release the tension either but when I do, I also unplug the saw and drape the cord over the tension arm as a reminder.
--Nathan, TX. Hire the lazy man. He may not do as much work but that's because he will find a better way.
I DT the large BS with the carbide blade, but never the 14".
Never have made the mistake of starting up without tension, but do feel guilty finding I forgot to DT the large saw between weekends.😔
Cool reminder pucks Jim, may save a blade or even some fingers some day!

Thanks, Bruce,
Hi Lazyman. I think sticking it on the blade would be the ultimate warning location!!!!!!!!!!!!!!!!
