First Light XXXI

The next section of the lantern build I wish to describe is that of constructing the infill panels for the gable ends. These are relatively straightforward, tongue-and-groove floating panels. I first cut the grooves in sides of the sub-ridgepole:


These grooves are places just flush to the front of the peg mortises, as you may note in the above photo.

I used a 0.25″ gauge block in the completed ridge slots and transferred markings to the stub posts which support the ridge:


From the stub-posts – tsuka as they are called in Japanese – the grooves were marked and processed on the upper surfaces of the short side keta, and then from there to the long side keta:


The completed groove on the long side keta:


Next I formed the grooves for the floating panel on the underside of the upper roof boards:


That took care of the grooves – it was now time to make the panels, which I cut out of 0.4″ stock:


After the panels were sawn out I trimmed to size by plane. Then I raised a field in the middle of each panel:


The corners were done in the re-entrant manner (iri-zumi, not to be confused with ire-zumi, which means ‘tattoo’) using various chisels:



I followed the chisel work with a quick plane pass to clean the surfaces up:


The edges and points of each panel needed a little more cut-out to fit into their slots – here’s a completed panel:


Now it was time for the fitting-up:


Without too much fuss, all four were in place:


The sub-ridge now slides down into position:


And here is the result, looking up into the gable:


Next time I’ll describe how the lower locking draw bars on the barge boards were constructed. Until then, dear reader, please take good care of yourself. Post 32 follows.

Anything to add?
