I've been running a Woodmaster CT 1" on my 20" Agazzani BS. I'm a hobbiest, so infrequent use. I keep it detensioned when not in use. The blade had been on the saw about three years when it broke. It was still sharp and still cut well. I started to hear hear a thunkathunka while resawing, looked for anything wrong in the guide settings (none found), and then shortly after the blade broke. Not at the weld. I got three or four years out of the first identical blade as well. I use the Laguna ceramic guides set close to the blade, but not in constant contact.
Is this lifespan to be expected, or should consider that I am doing something wrong?
Thanks,
Nelson
