I am having some sever issues with all my tool rest" binding "not gliding like they should. One tool rest is cast iron and two others are rubust. Called robust which are awsome to deal with but havn't get to the issue of the cause. Now I can not think what it could be I use red 3m cloth to clean any gunk off the rest and tools, and in conjuction with the 3m cloth I use CMT bit and blade cleaner and Top coat cast iton cleaner.... now to me they feel fine for 3 -5 mins. of turning then they start showing wear marks on both tool and rest and have drag on them ... Any help would be great.... Could it be possible these cleaners did something to the metals integrity some how.
