What a mongrel URL to paste - spaces and square brackets = FUN FUN FUN

I feel like I should get one now for my Dremel, my 2HP 1/2" collet woodwork router is tad large for the more delicate panel work I may do one day, but it would work fine for larger holes (router bits)

Oh yeah, spiral up cut is the go for the router bit for smoother cutting action and swarf removal.
