Ok, this is very humiliating, but it goes to show we are all human!
The other day I was running a board through my bandsaw (basically ripping a 3/4" maple board.) I didn't notice too much that the kerf closed very tight on itself after I cut it. Since I didn't want to rip the board all the way through, I was going to back out the wood from the blade. Usually, I turn off the saw and do it that way. However, since I was in a hurry (yeah, I know....) and it wasn't backing out when the saw was off, I turned it back on and tried to pull it out. Well, I forced it a little too much and POW! At first thought I thought I broke the blade. However, all that happened was that the blade slipped off the wheels. The blade did suffer some damage in about a 2 inch area where there is now a small kink in the blade. When I reinstalled the blade and ran the blade around with my hands, the blade now wobbles a bit at this kinked area.
A few questions:
1) due to the fact that the blade came off the wheels, did that mean my tension on the blade was too light? Just curious.
2) More importantly, can I hammer out this small kink with a ball/peen hammer on an anvil? It is a bi-metal blade from Lennox.
