Post 41 in an ongoing series describing the design and construction of a kabukimon, a type of Japanese gate. This is a project for the Museum of Fine Arts in Boston. Post 1 in this series can be found here if you'd like to start at the beginning. Each post links to the next at the bottom of the page.

Working on the mortising task for the rear posts- here I'm drilling the first of two holes for the threaded rod hold-downs:
Right on the money:
The other one was completed a few minutes later:
It appears a bit off center, however the mortise wall (lower surface in
the picture) is nearly 1/8" fat at this point, so all will be well
The lower through-mortises were roughed out on both posts using the portable hollow chisel mortiser, and the post ends trimmed and planed clean:
I used the same shim which helped make the posts into their parallelogram-shaped sections to support the hollow chisel mortiser. It worked well.
A look down one of the mortises - the remaining interior clean up will be done by chisel and I will rout the cogged seats, just as was done on the main posts:
For the upper mortises, I had to tilt the mortiser - this was accomplished simply with a 3/4" (19mm) plywood shim and a wedge, setting the angle with an adjustable bevel gauge:
Away we go:
On the opposite side, the mortiser was tilted the other way:
The mortises were punched through without too much fuss:
Then it was time to pare the mortises out:
All done with these two sticks:
A look at a couple of mortises:
I think I'll move on to the wall posts and flanking posts next in the frame member processing.
I finished up slightly early today ahead of the "storm of the century" rolling in this evening. It seems we will get about 2 feet of snow in the next day and a half, and the roads will be closed for the interim. If we do lose power my hope is that is won't be for too long, and can stay nice and warm. Our fridge is stocked, the generator is on standby. If you are in the same neck of the woods as me, please take care over this period.
All for now, thanks for visiting the Carpentry Way. Next: Post 42
