Throwing my hat in the sled modification ring

A round sled can be made with a router and a piece of wood like a giant compass. Attach the router to one end of a strip of wood (a few inches wide and at least as long as your sled radius) then put a screw through the strip at the distance of the radius from the router bit. So if you want an 18" sled then put the screw through the strip 9" from your router bit (which is attached to the end of the strip. Then screw the screw into a large enough piece of plywood. Run it around like a compass to cut your perfect circle! You even have the center marked now by the screw hole.

There are many other ways to do this but that’s a pretty easy one.

For those of us without a temporary sled, this method could be used to make those dado impressions and for the circular cuts
