A Japanese timber framed garden shed

[GRadice]

I've moved on to the jamb and threshold for the doors. It is nearly the same construction as for the window apart from a difference in naming. Instead of a stool and sill there are the same pieces assembled as a two part threshold. And since the door threshold is longer there are two dovetailed and wedged tenons that drop into mortices in the floor beam. These prevent the threshold from bowing up in the middle. Yes, I could just screw them down or screw up from below, but what fun would that be? The ends have the same splines as the window stool to keep the ends from lifting up or twisting. Installation is also the same: cut the threshold a hair over length (and scribed to any deviation of the post faces from 90 degrees), then spread the posts with some reverse clamps to allow the threshold to drop in.

The dovetailed tenons:

And installation. Post have been spread a bit and ready to install.

Ready to tap down. Another quarter turn on the clamps needed for clearance.

And almost down.

Success!

And wedged.

And a tight fit at the posts at both ends. Whew!

I will say that I was a little disappointed in my first attempt with the window. But I learned a lot from that and I feel pretty good about the door.

Here is the rest of the window jamb. The sill has grooves routed to accept 1/8" stainless steel bar stock as tracks for rollers that I'll inset into the window sash. End grain of the upper jamb piece are covered with white linseed oil paint. The sill is joined to the side jambs with a housed through mortice and tenon. The side jambs are joined to the top with dovetails. There are holes drilled for mounting screws and mortices for plugs to cover the screw heads.

I have the external door jamb done almost exactly the same way but it is difficult to photograph in a way that shows anything interesting. Imagine the same but twice as wide and tall.

Although in essence just a simple box, the trick is that in modern western framing (at least in the US, an I assume in Oz), window jambs are built solid and square and them shimmed into a rough opening. Gaps are flashed and covered with trim and caulked. In this old school Japanese construction, the jambs also have to be square so the windows/doors don't bind but must be fit to the shed frame without trim or caulk. As a first time amateur I'm pretty sure mine won't be up to Japanese carpenter standards. I'm concerned about weather tightness over the long term. On the other hand, this is a shed. And I'm old enough that my long term is probably short enough to not worry about it.

We got a few days of dry weather. That allowed me with my neighbour's help to install the roof flashing. We hope to start installing the metal panels tomorrow. Since the underlayment is also on, the roof is water resistant enough to take the tarp off. At least long enough to get the panels up there.

And between rains we got a few of the terne panels up. It took more brain work that I like to figure out where to snip and fold the panels on the rake ends.; The manufacturers instructions were meager. But I think we have a system, now.

Roofing on sunny days. Windows in progress on rainy days. This time of year it is about 50:50 so I'm going back and forth.

Nearly done with the roof panels.

Windows parts are nearly done. I still need to chop mortices for the rollers and pulls, and finish plane before assembly.

External jambs for the windows and doors are done. The inner of each pair of windows and doors runs between the posts and the outer of each pair between the external jambs.

I added some temporary steps. The rise from grade to the shed floor is about 550 mm and man was I getting tired of lifting myself up in one go. Not as young, etc. etc. This is more civilized. Eventually the plan is have stone slabs but that will wait until the shed is finished. But wth the steps there another plus is that I can build a potting bench for inside, start moving gardening supplies in there, and my wife can actually use the shed during planting season (which for us begins right now) without disrupting my finishing the doors and windows.

I've had another go round with the roofing company to supply me the few remaining panels I need. "Sure, no problem, we'll send them out next week, " they said. That was a month ago. The latest is that they were going to fabricate them today. Not holding my breath.

I finished the gable pendants by adding a touch more sculpting and mounted them. I'm very happy with the way they look.

Windows are glued up. Here is a test fit today. They still need a little tweaking, and some glass and stops to hold the glass in place.

And 30 seconds of them in motion.

It seems my last post before the move may not have transferred over to the new site. And maybe none of you have been transferred over either? In any case, the latest update is that I have finally after many months finished the metal roof. My neighbour did all the actual climbing on the roof parts while I remained safely on the ground sniping and bending panels and cheering him on. We are both very happy to have the roof done so there will be no more ladders to climb. We left a few boot marks but that is fine with me. They will fade over time.

I'm pretty sure this is the only roof like this in my town of 60,000 people, and probably one of only a handful in my state of Oregon (population 4.2 million).
