Hello here this is my second attempt to blog shell boxes. The last one ended up in the wall art ‘Inverted World’. Well this one is a little less spectacular but is based along the same theme of curves. This time a curved pattern

but it will have stringing introduced between the colour changes as will become apparent as the blog progresses. The main woods are American Black Walnut and Sycamore with Yew stringing. I will be book-matching woods where necessary.

First step is to cut one piece of each of the main woods, 110mm square by 18mm thick.

This needs cutting into 45° triangles. An easy way is with a jig like this

marked up with an engineers square and cut on the bandsaw. The wood to be cut is placed in it and cut on the tablesaw, thus

To cut the necessary curves in this piece I used my Circle Cutting Jig
So to prepare the four triangles for cutting I first made up a sacrificial carrier plate from 3mm Hardboard (Masonite) like this

Then double sided taped the triangles together and to the carrier plate like this

The Sycamore is on top and the Walnut beneath. I clipped off the bottom corner of the wood so as not to snag the pivot pin on the Circle Jig. I then cut the largest radius

Followed by the smallest radius curve

After separating the pieces and cleaning off the double sided tape I had a stack just as before I started cutting. I flipped the pieces curved on both inside and outside thus

When you separate the top layer from the bottom one and re-arrange them you get this

When glued up each of these four triangular patterns will be re-sawn, producing the full pattern. You’ll see. Just be patient.
For the stringing I used the same method with the circle jig and bandsaw to produce curved stringing out of a piece of Yew. Placing it in the pattern like this.

I made up a simple gluing cramp jig to glue the assemblies up like so

and glued up two triangles at a time like this

The pressure of each clamp counterbalances the other here. The metal rule is used to separate the triangles as each is going to be individually re-sawn. In the next part I will do the re-saw and fully integrate the pattern.

Be seeing you

Thank you

I appreciate you enthusiasm, woodklutz. All I ask is that you don’t post the results before I have a chance to finish this blog. You probably don’t intend to but it has happened before on a previous project with someone else.

Nice one Martyn.
I always wondered if you cut the stringing or just bend it. I guess you cut it curved.

Looks like a cool box a coming,
Steve

Steve, I tried bending it first but the strain placed on the glue-up could lead to later failure in the glue line. So I finally opted for a cut curve. No strain, major gain (Jayne Fonda eat your heart out).

Larry, you would have come up with it all on your own anyway.

Martyn, I have learned more about how fancy boxes are made just following your blogs! You are a true genius and artist. This one is a little more than I care to tackle. Maybe someday ? !

Martyn, this is another great design. I haven’t digested all the technics you used in the “inverted world” yet.

This one seems a little easier (emphasize “seems”).

Thanks!

Thank you for taking the time to blog this and show everyone how you make these fascinating boxes. This one is sure a beauty! I don’t know if I will ever have the equipment to try one out, but it is still so interesting to see your process when you build one of these. It is going to be quite beautiful. I love the wood species you chose too. It looks like it will be another masterpiece! :)

Not sure I picture how the pivot pin is anchored to the bandsaw table. Very cool piece. Thanks for blogging about it.

Thanks Martyn. I don’t get a lot of computer time, I do come and look at the projects everyday if I can. I always look forward to your next project/blog, but I don’t get a lot of time to type up a thank you. Your boxes are incredible.

-- Mel,
