Subject : Cutting veneer "pie" shapes

Making a small bedside table top on 3/4" ply. It will have solid wood edging, so the center veneered panel will only be about 14" square. Veneer is birdseye maple. The veneer I have it not as wide as the table, so would need one seam if cut straight. Rather than use one straight seam, I thought I might use four right triangles for some visual interest. Cutting the first three triangles is reltively easy because even if they are off 90 degrees by a smidgen of a degree, they will fit together fine. But the fourth must fit perfectly, and make up for all the errors in the the other three. Being off even the tiniest amount from the degrees needed to fill the fourth spot will result in a huge gap or overlap. So how is this noramlly done? My first guess was that you properly cut pieces one and two. Then cut pieces three and four intenionally large. Tape it all up so three and four overlap at one seam, then cut that last seam through both layers at the same time - a technique known as "double cutting" in wallpaper installation. But it seems that doing it that way, at least with a veneer saw, will leave a gap the thickness of the veneer saw, and a properly sharpened veneer saw is bevelled on one side anyway. Am I right except I use a razor blade? If not, I'm stumped.

Your double cutting technique works OK with veneering, but when doing radial matches, there's a better way.

Don't go about it working your way clockwise or counter-clockwise in a circle, ending your work where you begun...instead, work on two halves, and then put the two halves together.

So in your case, you're doing a 4-way radial match. Start with four pieces, and cut each one to about 91 degrees. Piece together two parts for the left half, and two for the right half. Because the parts are proud of 90 degrees, you will end up with excess material. Use a long straight edge to trim the excess and make the left half perfectly straight and jointed....do the same for the right, and put together.

And not only that, but I see you are from Sandusky. I grew up in Fremont!

Wow! Actually, I'm heading through Fremont today. Work has me in Fremont pretty frequently.

Yeah, I think that given more time, you would've figured that one out. It's an easy concept. Just remember that it's the same concept whether you're doing a 4 part match, or a 24 part match...cut oversize, and joint both halves.
