I am almost done with my machine, but I can't figure out which router to use. I bought a 2hp wood router, but I've been lead to believe it is not a good choice if I want to work with aluminum. I am most interested in cutting wood, but I do want to work with aluminum up to 1/2" if possible as well as certain types of plastic.

I've searched this forum for the last hour and found nothing. I either didn't enter the right search strings or I just haven't found an answer to my question. I have also been doing research about variable vs fixed speed routers, but none of them seem to be what I want. Ideally I would like to find a router that can be geared down (someone told me this exists, but I can't find one).

Here is a video of my machine. I tested it last night and it is accurate to about 0.0002" (with no load). I was very surprised!

Any advice would be appreciated.
