Bandsawing logs Troubleshooting
I am creating some centerpieces for my daughter's wedding where I am cutting logs/tree limbs that are 4-6 inches in diameter and I am cutting them to ~5" in length using my bandsaw. None of the logs are green wood or are wet. All have fallen for some time before I started this process. The final step is to remove a 3" diameter center approx 3" deep (to receive a small Mason jar for flowers).
For cutting the logs to 5" long I used my bandsaw as the compound miter saw was too dangerous and sent the first log flying against the wall (lesson learned).
For most of the logs I used my 1/2" 4 tpi Tiberwolf blade that was essentially new. The bandsaw is a 14" Delta (1983) with a 3/4 HP motor that is likely original but still runs strong. There is no riser block installed. After installing the blades I adjusted the tension, guide/cool blocks and thrust bearings.
Most of the cuts I had no problems. However, I had a log that the band stopped moving and I immediately shut off the power and unplugged. Picture of the blade are attached showing how it bent. I inspected the log and there were no metal objects causing this, and once I received a new 1/2" 3tpi bandsaw blade I was able to cut the rest of that log and several other logs without issues. I did have a similar issue with a different log later (of course on the final log, different day).
1) can either of these bandsaw blades still be used (bent back, etc) or should they be discarded?
2) Any advice as to the cause of this problem?
