So I watched the Wood Whisperer episode on band-saw setup and tuning. So, I decided to try and tune up my 10" Rockwell. Yeah, the wheels were WAY out of plane, by about a 1/2", so I fixed that. I also replaced the steel guide blocks. I read an article that rated "Cool Blocks" as really good, but they're around $15. That same article said that if you had some hard maple laying around you could make your own. Well I had hard maple. I made 2 blocks for the top guides and left the steel bottom guides. The top thrust bearing was fine, but the bottom had seized up and had a groove the size of the blade. So I need to get a new thrust bearing before I finish tuning.
