I don’t know if any of you use that rotozip tool (yeah, the one you see on those infomercials)…but…they’ve just introduced new attachments…one of 'em being a plunge router tip. may not be your cup of tea, but sounds like a handy new way to go mobile. anybody use the rotozip spiral saw to cut out your finsheets (to those of you who make your own fins)?!
