So my thunder made a really cool high pitched screeching sound right before it seized up in the middle of a tattoo. My client looked at me and said "Do you think it's broken?"... good stuff

Later when i took it apart and checked it out, the motor seems fine, but the bearing is seized, or almost seized. Any ideas where i can get just the bearing? I'll replace the machine if need be, but it would be cool if i could just fix the bearing...
thanks
