I have a set of Festool Parallel Guides that I have never used, so I thought about selling them. Thing is, I'm wondering if there are any other uses for parts from the Parallel Guides? I already have some Seneca parallel guides, so I won't need the Festool Parallel Guides for the same purpose. I just hate to get rid of them, only to find out that I could have used some of their parts for some other purposes. Thanks for the help.
