We have recently purchased a yates 30 bandsaw. It was purchased through a dealer but ran in opperation in a stair conpany until it was taken out of service to be delivered to our shop. When we got the machine and started it up it vibrated very badly, and was basicly unusable. Arter talking to the dealer he agreed to do any repairs needed to get the machine back in working order. He removed the upper wheel and shaft housing. He took it to his machinist who sait the shaft was bent (about .008). but that he was able to true the shaft up and install new bearings while it was apart. Once everything was installed again we fired it up and although is is a lot better it still has a vibration. if you watch the top wheel when it is spinning it looks to have a slight wobble. The shaft has no play in it and according to a dial indiator is running true, which leads me to think the wheel is bent. If thet is the case can it be repaired . I have been told that a bent wheel is probibly not repairable, and that these 36" solid wheels are very hard if not impossible to keep ballanced. I would love to have this saw opperational, you can't beat these old monsters, but i'm begining to wonder if it's worth it or not. any imput would be greatly appriciated.
