This was a fun challenge…..but hard to photograph. Pics 4 and 5 are using this mornings sunlight. The mineral oil really darkened the boards, so the symbols tend to get lost is the mix, but live and learn.

Primary woods used are Padauk and Purpleheart, along with Walnut, Maple and on one board, Cherry.

People have been asking about how the symbol is done in end grain and I only have a few pics but here we go:

The symbol itself is actually very simple geometry:

In this case, I used a 1” round nose bit to hog out the semi-circles is each half of the block:

Glue a 1” dowel in each half (contrasting Maple and Walnut). (no pics sorry). I cut off the excess dowel in the band saw and then plane each half flat again.

Now use a 1/2” round nose bit to hog out a semi-circle into the dowels you just planed flat and glue the contrasting colors in each half (and plane back down, which results in this:

Use an 1/8” round nose to carve the 2 small circles and glue it all together to get this:

I should note too that the Incra fence on the router table is a real bonus for this kind of work… worries about matching up all these different cuts.

There is a blog HERE with some cutting and gluing tips..

Here’s a couple pics before the oil:

Thanks for looking!

Jeff you have done well. If you dig in the meaning of Yin and yang it goes DEEP.
Nice work my friend.

You have certainly figured out the artistic and accurate….
ebb and flows of end grain cutting boards.
The Yin-Yang “building blocks” is just another fine example of your keen skills and eye for detail!

Thanks for enlightening us….
