Lone Star

[kmealy]

Needed something to do, so decided to invoke my geometry (and impress my quilting wife) and make a Lone Start Quilt patterned marquetry, or whatever you call it when it's made from solid wood and not veneer.

Target:

Progress as of weekend, dry fit before assembly

Strips of wood edge-glued, walnut, white oak, butternut, cherry, butternut. Then miter cut into 32 strips and glue up in specific orders, in steps. Titebond original for edge joints, Quick&Thick for short-grain joints. Got the final fit and star all glued today and yesterday. Next to make the border pieces (hard maple) to create a square for framing.

!...Wow!! You've got the patience of a Saint. Those are all 30deg cuts? How thick did you cut the pieces?
Beautifully crafted, Sir.

Intarsia was the word I was trying to think of.

The strips were cut about an inch wide so the sides of the diamonds are sqrt(2) long. The angle of cuts is 45 degrees as there are 8 points. I am not sure how thick they are, maybe 3/16" I just ran the scrap thru the planer until they were all the same thickness.

The strips of 5 colors get shifted and/or flipped to get the pattern. The two odd ones on each edge are then trimmed off. This yields 8 points that are then glued up -- first edge grain to edge grain, then end grain to end grain to make 1/2 of the pattern, then straighten the middle line with a plane and join the two halves.

Beeeutiful...!

Nice work Keith but I wouldn't want to look at that after a couple too many. There was a name for that type artwork back in the late 60s /early 70s where the art was designed to make it easier to go into deep meditation but I can't remember what it was called.

Mandala? Is that what you're thinking of!

Not quite and that name doesn't ring a bell. It was the type of art that was impossible to tell depth and the relationship of the elements to each other. Some of the 3D cutting boards are like that where if you focus on one color and then another the relationship between them changes.

Reminds me of the illusions created a long time ago by various psychiatrists/psychologists and named after them...here's one place that describes some of them...

Kool, looks TME consuming. What did your quilter have to say?

"I would never attempt something that complex in a quilt."

A quick wipe with naphtha to preview what the finish might make it look like. Trying to decide, BLO, shellac, or both.

Fantastic, Keith, those colors will be outstanding.

Very well done.

Beautiful work!

What are you using for a substrate? Are you laminating onto a solid board or a piece of plywood? I ask because it reminds me of a chess table that I made some years ago (my work was not nearly so complicated!), in which I had a devil of a time keeping it flat. My squares were around 3/16 or 1/4" thick, and when I glued them to a piece of plywood, it caused it to curl. I had to kerf the heck out of the back, and then pull it down to the table frame with screws.

I learned later (hindsight being 20-20) that whatever you do to one side of a board, you are supposed to do to the other. Which is why so many chessboards are veneered, with a plain piece of veneer on the back.

Fantastic, I like the light wood background, it makes an exquisite wall hanging.

On the forum most of us were previously on the topic of whether to double up the tops of router tables came up regularly. I've never used a double thickness and I've never had a problem with my tops warping but we saw many who insisted on doubling up who did have problems. The reason I thought that would be the most likely culprit was the water in the glue not being able to migrate out of the middle of the lamination. You could say that it is because it's sealed on only the top side with laminate but a kitchen counter top only has laminate on one side and they don't warp (at least not noticeably). Probably particle board and mdf are less affected and the only table or two I made using plywood I never laminated on top of.

When P-Lam first came out we did a lot of counter tops over plywood,and later particle board. I think the difference might be the glues we used. It was all contact cement then,(solvent based) I used wood veneer checker board squares over plywood with Titebond II and it curled up recently, But full sheets with the brown Titebond panel adhesive (waterbased) it worked OK. I was doing it both just one side.

Charles, I think the term you were looking for is "op-art" (optical illusion art).
