First, we will simply add a second fence separated by an accurate triangle with same angle as the segment.
Make a sled and Prove the Concept for yourself
Look at the advantages:
1. Dead accurate segments every time with no test rings.
2. Saw setup not a factor in the accuracy.
3. Accuracy dependency contained entirely within the jig.
4. Transportability from saw to saw.
5. Slanted segments merely by tilting the blade.
6. Varing strip width not a factor.
7. Any segment number configuration with one sled
How the Wedgie works
Make the first cut with one fence.
Without flipping the strip, make the second cut with the second fence.
You can quickly prove the concept for yourself with three pieces of MDF, a wood strip that fits your saw slot and a 30 degree triangle.
1 ea. MDF 12 in. X 14 in.
2.ea. MDF 2 in. X 12 in. (Rip parallel)
1 ea Large 30 degree triangle. (Hobby Lobby)
1 ea. Wood strip to slide smoothly in saw slot.
Your first segmented ring will be perfect.
Assemble the test sled as shown.
The triangle must be snug on both sides with no gaps.
Make enough room between the fences for the strip width.
If you measure anything, you will take the fun out of it.
The angle of the fences to the edge of the sled is not critical either. The triangle is king.
Add the runner for the saw slot. Place the strip as to require trimming of the sled with the saw.
This does not have to be perfect either.
I used screws to mount it. You can glue it instead if you choose.
Cutting a simple simple slot in the strip with a bandsaw and a small wood screw makes a quick and easy adjustment.
Trim the sled and add a zero clearance ramp strip
Note the fences are labeled. It is not significant for this test but later you will see how important this is for more advanced segmenting methods.
Adjust the track strip screws to eliminate sideways movement in the slot.
The top side of the strip is marked with a wavy line and the fenceward edge is marked with a straight line.
We never flip the strip. Keep the topside up and the fence edge toward the fences with all cuts.
It does not make any difference which fence we start with for this. But we will start by making the first trim cut with fence A.
Relocate the strip to fence B and set against the stop.
Cut the first Segment
Relocate the strip back to fence A and cut the second segment.
We only need twelve so only cut twelve.
This is an experiment, right?
A quick test fit looks good.
A little glue and a touch up on the disk sander shows the good joints.
This is only the tip of the iceburg.
