I've thinking about replacing the metal top rollers of my bandsaw guide, by cool blocks, but as they are not available here I'm thinking in using teflon instead and make them myself.
Given the lubricant properties of teflon and the heat resistance that it has I think it could work.
Do you think that it could work? Has anyone tried anything similar? I've seen that some people use blocks of lignum vitae wood.
Any comments will be greatley appreciated.
Thanks in advance
