I have a Steel City Band Saw that calls for 105.5” blade length, I can only find
blades lengths of 105” can I use the 105” blade ?
Thanks Oscar

Try Spectrum Supply.

They cut and weld the blade to order from a long roll of stock. That’s the way it always used to be done, I think.

When it comes to specifying the length (after you have selected the type, width, tooth-pitch etc), you can add a fraction of an inch, at least by quarter-inch increments and I think for some blades on 1/8” increments.

... 105.5 is 8ft 9 1/2 inches. [edit OOOPs. I wrote 1/5 instead of 1/2]

So, for example, if you click on “Kerfmaster”, you can then specify the length
8 ft
9 in
1/2 “

then the width/thickness/tooth-pitch combo, for example
1/2in, 0.022”, 3/4 (alternating 3 and 4 teeth per inch, I think)

The price is then $17.00.

Or a basic carbon blade would be cheaper…

A good saw shop can make a blade any length you want.

Timberwolf makes custom order lengths.

You probably don’t need to order a custom made blade. (I’m 99.99% sure)

From Highland Woodworking:

We don’t know what bandsaw blade length fits your saw either, but fortunately it’s easy to find out. It’s especially easy, of course, if you have an old bandsaw blade that fits the saw—just measure its length. Make a mark on the inside of the blade, and align it with the zero point on a measuring tape laid on the floor. Roll the blade along the tape until the mark reaches bottom center again, and there’s your measurement. The exact measurement is just a target, by the way — if your bandsaw blade measures 114-5/8”, you don’t have to special-order that exact length. Try a blade of 114” or 115” length; it’s more than likely that either one will work just fine.

Most bandsaws will accept a range of blade lengths, sometimes with as much as 2” difference between the shortest and longest blades that the saw can use. If you don’t have a blade to measure, or if you simply want to know if a 93” blade will fit a saw rated to handle 92”, here’s how to determine the range of lengths you can expect to mount on your saw.

With no blade on your bandsaw, lower the upper wheel as far as it will go by turning the tensioning knob counterclockwise until the wheel moves no lower. Measure the distance from the center of the upper wheel shaft to the center of the lower wheel shaft. Now raise the upper wheel as far as it will go. Once again, measure the center-to-center distance between upper and lower shafts.

Multiply the shorter shaft-to-shaft figure by two, since the blade covers this distance twice in a complete circuit. Add one full wheel circumference, since the blade travels around half of the upper wheel and half of the lower. (Circumference is wheel diameter times 3.1416.) This sum is the bandsaw’s theoretical shortest blade length. Do the same arithmetic with the longer shaft-to-shaft length to find the theoretical longest blade length. Bandsaw Blade length listed in owner’s manuals is usually the average of these two figures, or a convenient whole number somewhere in the vicinity. In practice, your saw can use saw blades from a little greater than your shortest length to perhaps 3/8” or 1/2” less than your longest length. Example: the shortest shaft-to-shaft distance on our Delta 14” saw (with riser block installed) is 30”. Max distance is 31-1/8”. So the shortest theoretical blade length is 2×30” plus 14” x 3.1416, or 60” + 44” = 104”. The longest theoretical length is 62-1/4” + 44” = 106-1/4”. Thus we can expect the saw easily to handle any blade length from 104-1/4” to 105-3/4”. We describe the saw as using nominal 105” blades, knowing that a little more or less will work equally well.

That makes sense.

Still, to avoid having to adjust so much back and forth if you are changing to different blades periodically, I would want mine all the same length. (Still have to adjust the tension anyway, since narrow blades need lower tension).

Another factor is that the blade can’t really be cut just anywhere. I’ve never taken the time to look closely at the tooth spacing around the weld on any of my blades, but the guys cutting the blade probably have to fudge around a little – and it may not be practical to make the blade any arbitrary length. So I wonder if you order something and 7/8” if they really make it like that.
