How Many Routers Does Your Shop Need?
For most people, the answer is three
If you do a lot of routing, there’s a pretty strong argument for having more than one router in your shop. One route to take is to use a combo kit, with one motor and two bases — one for use in a table and one for freehand work. But Jeff Miller makes a good case for having three separate machines: one for the table, where you can run moldings, cut grooves, and tackle precise joinery; one for freehand routing, such as long cuts and stopped cuts; and even a small handheld router for small edge details and other delicate work. If you think three is too many, consider this: Miller recently counted the routers in his shop and came up with nine!
