...just to report that I got better than expected results by replacing the
guides on my 350.00 "Lobo" brand bandsaw with rosewood blocks soaked
in WD40, as per the post (not by me, a few weeks ago). And that's on the
top guide only, I'm going to do the bottom guide as soon as I have time to
turn the blocks on a lathe, as the bottom ones are round instead of square.
