metal cutting bandsaw blade

[PeterT]

I mentioned in a previous post that my band saw blade decided to part ways from the machine with a sudden clackety-clack. It didn't actually break but had developed a split to the extent it would not stay on. After the second mount I examined it more closely it had obvious hairline fractures which the pics magnify quite nicely. Its .75" wide x .032" thick x 10-14P? Starrett Itense Pro. It was on the saw for several years so paid its dues. Any idea what these cracks represent setup wise? Its at about the minimal tension to stay put. My saw is one of the typical offshore 7x11-ish upright / drop down style. I do think the twist path these saws impart on the blade is probably not healthy for them. I mounted my identical spare & its smooth a silk. But now I will be in the market for a spare so its ready when the day comes.

People have mentioned Allblades & possibly Thomas Skinner? I need oddball 85" length so custom weld length. What brand names & tooth pitch & any other features have you had good experience with?

I’ve got a starett blade on my machine been there a couple years too. Good stuff. Just keeps going. All blades will make a custom size.

I believe my local (Lethbridge) sharpening place stocks Lennox brand in bulk and can make up any length you like. I would imagine there are numerous Calgary counter parts to this service also.

I think those are typical stress cracks caused by the twisting/bending of the blade along it’s path. The metal work hardens over time and then the stress cracks develop.

Yup, AllBlades Canada should be able to get you a custom blade. They were less than $50 for a 100+” long by 1” wide for my saw.

You can also order on aliexpress - custom blade size. I ordered 3000mm 1/2" 1--14 TPI. Did not arrive yet. With ePacket shipping it was like 22 CAD. Supposedly bi-metal.
