Thanks James, that’s kind of what I had in mind. I’m not sure I have any ¼” MDF in stock, but maybe I can recess out ¼” out of some ½”. I need to make two cuts for each piece. one for the outside cut and then the inside.
I took this silly RotoZip Circle Cuter attachment apart and I can see why it’s so flimsy and I was thinking that if I could find a thick gasket or washer that will fit between the pieces, I just might be able to tighten it up.
I'm a little worried about the template because I have so many to do, I'm might screw some up.
