Those blades have to be pretty long. Really nice rehab job. Looks good as new.

The more I do, the less I accomplish.

Yeah I believe they were popular back in the 1970's
But I have read that blade fatigue is a common problem with them, Especially with wider blades!

Red face Craftsman 1957 3 wheel band saw

Mom bought Dad a Craftsman 3 wheel band saw (Seally) for Christmas in 1957. Dad use to cuss at the saw every time he used it, as it would break blades. Both parents are gone now, but I wanted the saw for the memories. The problem with the saw was due to low tension on the blade, and when you fed wood in, the blade would rotate and catch a tooth on the table top, and Bam!, the blade would break. You could tighten the tension knob until the tensioner rod bottom out inside the knob, and blade was almost tight but you could tell something was not right yet. Doing a search on the internet I did find the owner manual from 1957. Wow! Looking at the tensioner details there was a cylindrical spacer between the Knob and saw that causes the adjusting knob to sit further out, giving the assembly more travel. So when dad changed the blade at one point the spacer fell off and he probably did not notice it. ( fell to floor or something). I made a space about 1/2 inch in length, with hole the size of the tensioner threaded rod. I am now able to tension the blade to get a Guitar 'G' note when you pluck the blade. The saw works great.

A 3 wheel band saw has a thinner blade. Using a 2 wheel blade that is thicker and bent over a smaller diameter wheel cause the 2 wheel weld to break. Welding on a 3 wheel blade uses a different process to get the strength at the weld with thinner metal. Cheap 3 wheel blades are welded the same as a 2 wheel blade and will break. You must get a 3 wheel blade that has the quality 3 wheel weld or the blades will always cause you headaches. My 1957 Craftsman band saw is running great, cuts straight, and wished Dad were here to see what all the cussing was about!

Welcome, Mr. Mike. Great info. If you have the time, perhaps you could check out the tool manual archive and add yours if it's not already there?

The one that we had at a sign shop that I worked at, had a built in welder. It just butt joined (with adjustable spring tension in the jaws) and an electric arc. The wheels weren't all that small on that saw though because it was pretty big.
