Every few months I try and take a day or so and do a thorough cleaning of my shop, cleaning the sawdust from the innards of my machines, blowing the dust out of the motors etc. Then, after cleaning any surface rust or staining, the metal gets a nice coat of wax.
It’s not my tip, but those who have a bandsaw and have difficulty getting it running smoothly, should take a good look at the following video. I did and follow this for a really smooth time with my bandsaw. Hope it helps someone . https://www.youtube.com/watch?v=wGbZqWac0jU
When buying new bar clamps it is good idea to wax the bars before you start using them. That way errant glue that drips on them will come right off. I didn’t do this on some parallel jaw clamps and they had so much glue on they wouldn’t slide on the bars. It took me 2 hours w/ heat gun and a file card to get all of the glue off on 4 clamps, lesson learned.
