Hi all,

Finally I'm able to get my 17.5" project under way.

I need to cut a series of 50mm diameter holes into 15-30mm plywood. These need to be accurate as they will be holding the truss poles in place (there will only be three truss poles). Hole saws are no good- too big. I have both a drill & a router. Any suggestions?
