I'm a novice woodworker, I recently bought a DeWalt DW621 router. It's seems to me to be a fine tool and I have been experimenting to see how much I can do with it. I've been reading Gary Rogowski's "Router Joinery" which seems excellent.
My question is this: the router comes with one template bush which can be attached with two screws. How is it possible to attach other sizes of bushes? I have seen sets of them for sale.
I'm sure I can achieve everything I want to using bearing bits but I'm intrigued....
