I'll try that.Felt, arts and crafts shop.
Looks very much like rubber. Hard too. Can't see it doing any good at all in its current state. I'm wondering whether I even need wipers if I have covers. Mill has one shot oiling.The pic looks like rubber? I guess it could be felt where old oil has polymerised..
Mine only had wipers on the main ways. A metal retainer screwed into the slide, holding oiled felt to the ways. I copied this for cross slide and tailstock. The felt, I used Lidl stuff, sticky backed ones intended as furnature protectors or something.
