- Tensioning a band saw is not a difficult task but is crucial for a band saw to work properly and safely. In this video I review a quick and easy way to tension a band saw without a tensioning gauge, like most old band saws are missing.
Quickly, the steps are:
1. Fit the blade to the wheels and adjust the tilt and tension so it stays securely in the bandsaw. This is an initial tensioning, not the final one.
2. Move the depth of cut adjuster to the highest position & move all thrust bearing & guide bearings/blocks out of the way
3. Turn the bandsaw on, you should see the blade with a standing vibration in the work area
4. Increase tension until the vibration disappears and the blade remains rigid and stable.
5. That’s it!
Always make sure to use the proper safety procedures and use caution when working with power tools like a bandsaw.
Thanks as always and be safe,

I like that guideline for tension. Much more clear than "just push here, you'll get a feel for it eventually"
Glad you found it helpful!
Thanks for video 👍 .Have a nice day And fine cuts.
Yes, I agree new blade. I'm going through all your vijeos and maybe you've already changed it. I have a 1936 craftsman and its definitely not the first I have used. When I was building yachts there was a general purpose blade setup on one saw and a more detailed on another. That's not always feasible but I would recommend if you aren't doing too fine of curves to get a wider blade. Just my thoughts. Great vid. New subscriber
You were totally right. I swapped it out for a wood slicer in this video (th-cam.com/video/qDRA40XC7hU/w-d-xo.html ), worked wonders! I do very much appreciate the wider blade. Hoping to upgrade at some point and move to what you suggested with two different blades. Glad your enjoying the channel and to have you around!
I am enjoying your videos on this saw rehab. Do you happen to have a link to that thrust bearing that you used as a replacement? I was hoping to find one in the video description.
Shoot! You’re totally right that it’s not there! Here’s a link to the ones I used! amzn.to/2UpGsrE
Thank you for responding with the link. Very helpful!!
@@lucashurt6639 glad I could help! Let me know if there’s anything else!
Happy Woodworking!

Nice work. I was just searching for these bearings for this same saw. Is the shaft size such that it fits into the old sleeve or does the sleeve get removed?
Sleeve gets removed if I remember correctly.
I have snapped a thrush plate of an old Sears band saw. Can I replace by a bearing? Where did you buy them from? Thanks.
Sure can! In fact I did the same thing exactly, overworked my thrust plate, snapped it, replaced both with thrust bearings. Below is a link to the thrust bearings I used.

How did you mount your motor? I have the same pedestal stand but I cant seem to get to the motor to mount correctly.
Do you have the original motor mount for it? Mine has a slotted plate where the two U-Bolts secure the plate to the pedestal column and the motor mounts to the plate. If you shoot me an email, I can send you a photo of my setup.
@@NorthwestCraftsman Yeah thats what i have. I just cant seem to it it straight on the pedestal as Im trying to tighten it its starts dipping and then ends up crooked.
I had to tighten mine in two phases. First time to get pretty much all the slop out, then I smacked it when a dead blow hammer on the back to remove any slop that was there, wasn’t much for me but added a small amount of tension to the belt, then I retightened everything and it’s been tight since.
Are your bolts loose after it shifts?
@@NorthwestCraftsman No. I cant them tight but as I tighten it it goes crooked. I thought maybe I had it on wrong but it looks exactly the same as yours is.
Which direction does it go crooked?
