The more I look at the Makita videos, the more I'm convinced that the MLCS Rocky 30 is a re-branded Makita. Not only the router itself, but the plunge base also.
I called MLCS and asked about a guide bushing adapter for the Rocky 30 plunge base and they said they are "working on getting one approved" but it could be a few months.
The description for the following adapter says that it fits the plunge base on the Makita RT0700, RT0700C, RT701C and RTO701CX3. Assuming that my plunge base is indeed a re-branded Makita, this is what I need in order to use guide bushings, right?
(P.S. I played with the router this weekend and am working on a review. Soon!)
