After getting the real way to setup a vertical bandsaw off a YouTube vid I would not hesitate to adapt Delrin or UHMW guide blocks to this saw. The fact of the matter is the blade isn’t supposed to be riding on the guides constantly and at the speed a metal cutting saw is supposed to run at, either of those plastics would last forever. But I also don’t use my bandsaws for cutting curves.
My 14” vertical bandsaw has its original metal with rubber insert feet with some wheels welded on the side to move it like a hand truck when needed and never moves around once put into position. Now if there was bodily fluids all over the floor that would be a different story, but I don’t have any intention of butchering on it.
