I suppose I too am in the minority here also. I agree with Marks thinking of the gas engine vibrating the CA hinges. I went with the Robart 3/16ths all around. Flex the surface to 45 degrees-- take a felt tip pen and mark the place where you want the hinge-- Use the Robart tool to line up the drill bit so that it goes in at 90 degrees-- and that's it. Be sure to use a tooth pick and place Valsaline in the hinge part so that the epoxy does not seep into the hinge.
