Topic tags/keywords: band saw blade

I have a Craftsman 12” where the blade broke. In replacing the blade, I bought a 12” blade from Lowes that is too big. I’ve tried adjusting the saw all the way out, without success. Is this usual for a store-bought blade, and is my only option to buy from Craftsman?

I would never buy a blade from the manufacturer. There are dozens of sources for band saw blades – you just need to know the proper length. And you can always have them made to any size. Your manual should have the proper length blade needed – not all 12” saws are the same, particularly across manufacturers and models.

Cheers,
Brad

I have an Atlas Press Co 12” band saw that uses 82” blades. You can use a piece of string, or anything flexible, to wrap around the wheels and mark the length with a marker. Then stretch it out and measure.

Since you hav a broken blade, lay it out on the floor and measure it. It is probably 80”.

Try a Timberwolf or wood slicer much better blades and performance. LINK

I recently called them and asked what blade would work best for my circle cutting jig. The blade they recommended works great, as did the resaw blade I bought last year.

It depends on which Craftsman 12” you have, the newer Rikon model or one of two older models. That’s three different blade lengths, I think. Mine is one of the newer ones and Olson, Timberwolf, Highland woodslicer, and others carry that 89 1/2” blades.

Don,

If your BS is an older model, vintagemachinery.org may have the manual for it which will list the blade size you need. Also, many saws have the size cast or stamped into the frame. As mentioned above, most big box stores only carry blades for modern machines which may or may not be what you need! My 12” C-man BS is a 40’s vintage machine which needs an 80” blade, a size my big box’ers don’t have. I ordered a Timberwolf off of Amazon and love it!

Try Amazon, Rockler, Woodcraft or Highland.

I’ll bet your blade is 80 inches. Measure it by putting your sliding rule around it from wheel to wheel.

I have a 12” craftsman, 89.5” blade. I order them from a shop in NC called woodcraft bands. They are about 1/3 the cost of buying from sears.

Thanks, guys. It is an older machine. So old that the model number 113. 243410, doesn’t even show up on the Craftsman website! I’ll try your suggestions and let you know how it goes.

Hartville tools sells blades at a decent price with no shipping. I’ve bought else where for less but the shipping ruined the deal.

Two things determine the length of a band saw blade; wheel diameter and the distance between wheels. To get the correct length, 1) Find the circumference of the wheel. In your case; C = 12” x 3.14 or 37.68”. 2) measure the distance between the center of the top wheel to the center of the bottom wheel. 3) Add 37.68” to twice the distance measured in step 2. Round up or down to the nearest whole number. Not all band saws have the same dimensions, unless they are exact copy clones.

Or just use an online calculator like this one over at the VM site:
Belt or Band Saw Length

Of course, if it’s one of the three wheelers, then you have to resort to other methods such as those described by some others above.

Brad
