Segmented Zig-Zag

>Bob,

Basically all you do for a zig-zag, is 1)laminate the wood you want, let's say black on top and white on the bottom, when done with the lamination done, when seen from front and back sides you will see both black and white, and from the top you would see only black, etc, 2) Place the laminated strip on your TS with black and white side up, set your miter guage to. let's say 25 degrees, and crosscut the lamination in strip wide enough for the segments you need (say 15/16" wide for a 10.25" diameter) 3) now what you have are paralligrams, cut the pointy ends off so that you have rectangles, 4) now flip every other piece right to left, and then take the rectangles with black side up, and cut them into your segments.

That is the quick and dirty - the tough part is doing is precisely enough so that everything lines up when you glue it into a circle.

>HI Mark,

I didn't follow the strategy of your instructions.

As I read your instructions, you made a two-piece laminated board (long and narrow), placed it on edge, cross cut it into short parallelograms with two faces at 25 degree angle. Here is where I got confused: You cut the points off of the parallogram to make rectangles. Is it the points that you want or the resultant rectangle? What I have visualized leaves a sizable gap or simply a straight (but shorter) board just as you started. I know I have my brain in backwards so please help!

>I know, it is tough to visualize if you have never done it. Once you have seen it, it becomes a simple concept.

I will see if I can take a couple of pictures tonight, and post them tonight or tomorrow to show better.

>Thanks Mark

I have been playing with styrofoam to try to picture this--if I understand you correctly,when you go to cut the parallelograms into rectangles (step 3), you have to set them on the table saw so the parallelogram faces are on top and against the table and cut so that the lamination between the black and white wood runs at an angle to the edges. (correct?)

If so, then you must need to start with a thicker lamination than the zig-zag ring you end up with?

Guess I better go clean up the styrofoam & start figuring out how to make some sleds & jigs!!

Thanks again,

Bob

>Tug, an easy way to see the ziz zag develop is to take a 2 inch piece of paper 4 to 6 in long and clear on both sides. Draw a line down the middle ( 1 inch )length wise, on the front and back of the paper. Cut strips at about 45 degrees, about 4 or 5 strips. then alternate the strips,ie turn every other one upside down and you will see the zig zag develop.
