    4-way miter

    I'm building a new cross for our church and want to have the middle meet in a 4-way miter (is that the right term?)

    The mitered pieces are 5" wide pieces of 3/4" ply. Do any of you have experience in cutting a joint like this? Can you offer any pointers (no pun intended )

    For strength I would use a 'plus' shaped spline (kinda like a floating tenon) or even easier, a 'plus' shaped piece of hardboard laminated to the back at the crossing point(?).

    4-way miter

    I should have been more precise in my description. The picture does not show but this is actually a three sided box that will slip over the existing cross.

    The four sided miter is only the front piece the sides will be 5 inches deep and pocket hole screwed into the front pieces. These will butt joint at the inside corners and be screwed together. I have no fear about the strength once it is all assembled.

    I really thought the four sided miter would add some visual interest to an otherwise simple design.

    4-way miter

    success!

    I must have slept through that part of my high school geometry but it seems that if I use a stop on the miter gauge set at a 45° angle the point will always be dead center. So, as long as I have faith in the setting on the miter gauge things work out.

    if you mark the short point of the miter and set your stop to that dimension then as you said, cut, flip, cut should do it. Run a test set first but I think your spot on

    Doh! Yes, yes, I agree. The points coming together look very nice ;-)

    If you cut the horizontals on one side of the blade, and the verticals on the other side ...

    Looks like you have it pretty much dialed in, but I thought I'd throw another look into the mix just because I thought it looked cool. This cross was designed for a friend, but in the spirit of true procrastination, and because I'm not sure how to cut the joint, has not been built yet. Kind of a fancy half lap. It would scale up nicely.

    4-way miter

    Ted, I like that approach. Looks pretty straightforward to cut (to me). Might need a little chisel cleanup, but doesn't seem that tricky.
