I swapped out the bearings on my 10” for blocks a long ways back for the same reason and have never had an issue. Honestly, I’m not convinced you need rear bearings anyway…as long as the blade is sharp, you should be leaning against that bearing anyway, right? Small bandsaw’s seems to be plagued with ‘works fine when it’s new (and clean) issues’. Guess that’s the nature of the beast!

Ryan/// ~sigh~ I blew up another bowl. Moke told me "I made the inside bigger than the outside".
