    Default How should I?

    I need to surround (frame?) a cutout in plywood so that the edge is hidden. As I don't want to waste wide planks on the job, I'm using 20mm rails and stiles with quarter arcs cut across the grain to (hopefully) end up with a surround where the grain is aligned.

    My problem is working out how to cut the quarter arcs squarly so that they can be glued cleanly to the rails and stiles.

    How would you approach the problem?

    A piccie should make it clearer what I'm doing.




    Thanks guys

    Hello Darce,

    I'd cut the edges for a clean butt join before cutting the
    arcs out, it would probably be easier to sacrifice a wider
    board, but if you insist then that's the way to go i think.

    As for the correct angles, it will be a 45 degree cut each
    end. I suggest you start out using a piece of mdf.
    I don't have the math to work out
    the distance between each end so it will be trial and error.
    Once you get the distance right, cut the arc out of the
    mdf and use it as a template to cut the 4 arcs.

    Now just to complicate matters i think at the very least
    a lap joint would be required here, that should be a min
    of the rail width. An accurate mitre box and a tenon saw
    should take care of this job fairly easily.

    How are you cutting the arcs out?

    Thanks Col, I was cutting the arcs with a scroll saw, now I think I might use a router instead. Cut squares and use a circle cutting jig to rout the arcs. Strength isn't an issue here as they'll be rebated to fit within the cutout.

    Darce,

    Yeah, i missed the bit where you wanted the grain to align.
    Squares will be better, my way would have had the grain
    running 45 degrees.

    cheers
