I have an arm with carriage from a scrapped RAS. Before I get rid of it, I am trying to think if I would ever have a use. The carriage runs smooth and without play, so would be a good set of ways for something. But unless I can think of a good use, it needs to go. I can't really think of any use with a router that would be worth the trouble and floor space. Almost always other options to do same thing. Any ideas?
