Landscape 2

I have an order for a few coaster sets, so I’ll start on those as soon as I get final details on timber types.
Once I finish those, I’ll start on my next competition landscape piece. This has to be in by the end of March. This will be my most ambitious project yet. The jigumi will be 1090 x 630 mm (about four times as large as my first landscape), and the longest diagonal piece will be over 1200 mm. This piece will have 36 mitsu-kude joints, so 36 joints in exactly the right position at exactly the same intervals for the jigumi to fit together. Each one of these joints will be cut by hand using my Nakaya kumiko saw (with a new blade inserted - the saw on the left). At a rough guess, there’ll probably be more than 10,000 individual pattern pieces.

This is my CAD drawing of the jigumi. The pitch is 35 mm, and the kumiko thickness (mitsuke) will be 1.6 mm.

The first thing I have to do is make up a couple of new jigs for the angled cuts. The jigs I’ve used to date are too small.

Putting the jigumi together is the most fundamental part, but it will be the most difficult. Most kumiko shokunin in Japan use radial saws, many computer controlled, to cut the jigumi, but unfortunately, I don’t have this luxury. I have to cut mine by hand. A major challenge, but I’m sure my skill level will be much improved at the end of it. Once that’s been done, it’s then simply a matter of putting in the patterns. I’m thinking of trying a couple of new patterns that I haven’t made before, and some interesting variations on patterns I’ve already done.

I’ll chart my progress (including any disasters) here.
