I use six segments per layer when I am making a typical block rim. Each segment is 2 /12 inches wide and 7 inches long (measuring from the longest side). I find it useful to lay out my segments in advance so I can work around any defects in the wood.
I often cut the segments on my miter saw. My Delta saw doesn’t have a positive stop at 30 degrees, which is a real pain in the neck.
If you don’t have a miter saw, you can build a jig for your table saw. This jig holds the wood at a precise 30 degree angle as it moves through the saw.
The bottom of the jig has a hardwood runner that fits in the slot of my table saw.
This picture shows the jig in action. For photographic purposes I removed the blade guard and took the picture with the saw turned off.
Because I built this jig to fit my Shopsmith, I can swap the table saw blade for a sanding disk and sand the edge to perfection.
