Re: What bit do you use/circle jig ?
you can use a fixed base router to make circles, My fixed base you can still raise and lower 1" Set up your circle jig and see where your router has to start, You have to drill a hole where you are going to start the router, set the router so the bit is showing about 1/4inch, put the router in the hole you drilled, turn on and do a pass.
Stop the router and adjust to 1/2" do anouther then a hair over 3/4 and uor done.
This is what I have done and have had no problem, Just dont force the router let it cut the wood its self.
