This board was done as an experiment to another design I’ve been kicking around in my noggin….I wanted to see how well the diamonds would line up using a new jig I set up…

Bottom line, I need to make a few adjustments, mostly to some of the glue up steps to insure the alignment. Pic 5 shows the mis-alignment….

The board is Soft Maple and Mahogany. I had some nice thin Mahogany around, so that’s how that decision was made…

I’m kind of on the fence about the edge treatment….used a bowl and tray bit to carve through the Mahogany border into the Maple…...appreciate your good or bad comments on that one….

I’ll probably do a blog on the next board I build, but I anticipate someone will ask before that… here is a preview of the process:

Built a 60 degree jig for the router table that uses a straight bit, and it will give you nice consistent angles:

Glue the thin strips:

Run them through the planer to true them up:

Mill some “hollow inserts” on the same jig:

Then glue them all together…..this step needs some improvement:

After you cut off the waste and plane them up you get this:

You can take it from there… was a good experiment because I learned something…...just can’t remember what it was right now….

Thanks for looking….

Jeff, thanks for the tutorial. I think it is a good looking board. I would not have the edge groove go through to the maple, but I think that is a matter of personal preference.

I like the edge treatment, for both form and function!!!

When a display of various cheeses & fruit are presented, the “center of gravity” of said board, is not in the center of the board. Your edge treatment forms a handle that facilitates lifting the board, by placing your hands where needed to balance the board, thusly keeping it level.
Tossed salad is one thing…
Tossed cheese is just NOT right!!! ;^)

I like the hollow diamonds! Another JL7 original!!!

Your design work and jigging is fascinating. Looking forward to your blog!

Jeff I have spoke of my amazement of your accuracy. Like all things it is work in progress.
I am amazed that you have the patience to do this work. I don’t.
Nice work and well done.

I’d say this qualifies as cool Jeff! Appreciate the explanation, different than I thought on first look. I really like the edge detail. Thanks for sharing.

I am very envious of your ability to think in 3 dimensions. My brain just doesn’t work that way!

The edge treatment looks like you glued up 3 layers rather than routing the groove. But it appears very functional.

Like the design and thanks for the extra construction pics .
Sorry the edge treatment is not fitting as it makes it look like two boards glued to a core and not a solid board even so the idea as a grip is good .

I hadn’t really considered how the edge makes it look like an Oreo cookie…...thanks for being honest. It was done for the function, but it’s different for sure…..

Appreciate all the comments….and yes Marty….

Nice one Jeff.
That design lends itself to misalignment by just the smallest thickness change. I think it came out really nice.

I am also not fond of the Oreo. It hides the real nature of a solid board.

Good job Sir. I like it.

Steve – you’re right, if the thickness is wrong, it is by a factor of 2X.

Thanks for the comments.
