I didn't want to hijack the other bandsaw thread, but I have a question that Bruce's answer sparked. I did the upgrade on my Rikon bandsaw, it now has sealed bearings for the guides which i like...for the most part. The lower set however seize with sawdust, and they're sealed. I've replaced them several times with new sealed bearings, and in short order they're seized again. I just replaced them again today just before posting, so we'll see how long they go. Question is, how can one prevent the sawdust from getting into the bearings, and is it a dust collection kind of fix? I saw someone else on here that added a pvc shop made dust collection gizmo just under the table, and I wonder if that is something that would work for me? I'd like to see pictures of that again, been a while since I found that, and guess I could find it again, but if anyone has ideas for this problem I'm very open to suggestions. Bearings aren't that expensive, but I don't like having to down the machine for a while when I'm in the middle of using it for something. Routine service intervals are not often enough for this problem, at least for me.
