With lots to do around the house, I've not had much modeling time. I did finish the deck planking, though!
I wanted as much deck framing as possible to show, but I still needed to accommodate three long gums. I started the holly planking at the outboard mortar pit bulkhead and worked my way to the waterway. The margin p[lank was custom fit. It turned out to be as wide as the others at it's forward end, with a bit of a taper aft. It turned out pretty well.

Thanks guys. for all the "likes"!
I needed to figure out a way to make the hatch cover boards. I planned on using boxwood for the color contrast. The boards are about 5/64" thick with a very slight curve to them that matches the curved coamings. But bending the curve and getting the precise length right cutting strip stock was going to fail! Too hard to get consistency in the four boards. Here's what I did:
I cut up a boxwood blank the fit into the recess where the boards sit. It was thick enough so it stood just proud of the highest point on the curved coamings. Then I traced the coaming top lines onto the 4 edges of the blank. I used double sided carpet tape to tape the blank to a block of wood, keeping it perpendicular to the table of my disc sander, and parallel to the disk's face. Using my variable speed disk sander on LOW speed, I sanded the curve into the blank!
Once I was satisfied with the curve, I took the blank and simulated the four boards by scoring them in and darkening the score lines with very thin pencil lead. It worked out well!

I started work on the hatch. The coamings are 7/32" thick bloodwood and jointed by half laps at the four corners. The coamings are also beveled inward by 10 degrees on all four sides. How to do the beveling easily and accurately? I decided on a jig!
Basically the jig is a slice of wood, angled at 10 degrees from the horizontal. When the face of a coaming is sanded such that it is square up against the Byrnes sanders disk, you know the angle is a perfect 10 degrees. The hatch frame is attached to the jig with two sided carpet tape.
Sanding the four sides took about 20 minutes.

Thanks, guys!
The complicated anatomy of the ends of the angled bulkheads actually makes fitting the outboard and transverse bulkheads easy. They are cut a little long at a 90 degree angle. I then "sneak up" on the final width with the Byrnes sander.

Pat: I'm eyeballing the cuts, but I have a plan view rubber cemented to the bottom of each blank to guide me!
I prepared the diagonal bulkheads for installation. The backs of the 4 bulkheads are supported by diagonal carling which are inset into mortises in the deck beams and trimmer beams. I decided to make life simple and simply butt the diagonal carlings in place. I carefully cut them to size, then glued them to the back of the diagonal bulkheads. The bulkheads are built with two boards. I simulated this by scoring a line and marking it with a pencil. Once the glue dried, these were epoxied in place.

he diagonal bulkheads are the most difficult because there are two angles on each end that need to be cut to form a point. Fortunately, the andles are 45 degrees and the "point " is a 90 degree angle! I set my Byrnes disc sander table to 45 degrees and "cut" the angles very carefully. The photos show some finished bulkheads and how they butt up against each other. The rabbets are to accommodate the side covers, which are part of the mortar pit housing. I'm not sure if I'll include this!

I started work on framing in the mortar pit by milling the bulkhead blanks out of boxwood. There are eight bulkheads, each 3/16" thick. The fore and aft bulkheads have no rabbet along the top edge, while the port and starboard bulkheads and the diagonal bulkheads do. The rabbet on the diagonals is 5/64" X 5/64". The rabbet on the port/starboard bulkheads is 5/64" X 1/8". The diagonals have complex geometry, which I'll do using the disc sander. I don't think this kind of precision could be reasonably expected except by using Byrnes tools!

I'm back at it! I just finished planking the inboard bulwark ceiling planks, then cut the gun ports and the sweep ports. There are very subtle treenails in place. I used birch toothpicks and they blended in well with the bloodwood planking.

Next I installed the spirketing planks. These are the two lowest planks of inboard bulwark planking. They are thicker than the upper inner bulwark planking and the topmost one is rounded over at it's upper edge. I did this using my Dremel mini-router table. The waterways and all inboard bulwark planking will be bloodwood.

I'm back in the shipyard but there are still tons of things to do around the house and yard. Hard to find time for everything!
I cut the stock for the waterways. The two bevels (three, really) are a little tricky but they came out OK. The stock is a bit thick so soaking or using a clothing iron the bend the waterways to the narrowing beam at the aft of the model didn't work. My solution was a heat gun!
I put a scrap of plywood on the bench top, then the waterway stock, then another narrow piece of stock on top of that. I clamped the "sandwich to the bech top and used another C-clamp to pull the waterway into it's curve. With it in position, I heated the waterway for one minute with mu heat gun, aiming at the spot noted by the arrow. The plank stayed curved with no spring back!

I finished the deck framing. No poly on the upper surfaces yet. Next up is working with bloodwood for the hatch coaming, the waterways and bulwark planking.

I cut the pillar under deck beam #2 to length. Here it is, dry fitted. I plan to pin it to the keelson and the deck beam. The piece of holly near the footwaling is just a measuring stick I used to locate the pillar on the keelson

I turned a few pillars out of swiss pear to support the upper deck beams. They rest on the keelson.

I cut and fitted all the ledge for the deck as built so far. Nothing glued in place yet...all friction fit!

I installed all the hanging knees, lodging knees and carlings from the aft end of the section to the forward edge of the mortar pit. I'll add the ledges to finish this part of the deck before adding the beam arms and the rest of the deck framing.

Here is where I am. I've got all the deck beams notched and have started installing them from aft forward. Because the beams sit in notches in the deck clamps, they can't move. Fitting the hanging and lodging knees is really finicky if you want a tight fit. I'll add the carlings and ledges and finish the deck up to the forward end of the mortar pit. That's where the hardest part of the deck starts: fitting the beam arms. I cut them generously and left them a bit thick. They are so long that I have to account for the deck camber.

A friend and collaborator, Joseph, is doing 3-D drawings of the plans and we are making changes to simplify construction for those less experienced. This includes eliminating the rise in the frames moving aft as well as eliminating the narrowing of the hull moving aft. He also drew up the deck such that all the beams, carlings, ledges and lodging knees were the same thickness (pictured). I decided to use stopped dadoes on the beams to seat the carlings. Thus the carlings would be thinner than the beams. I'll keep the ledges and knees the same thickness as the carlings, though, to simplify construction. I think it will look fines.
Rather than use a razor saw, chisels and a hobby knife to cut the dadoes for the carlings, I looked for an easier way. what I did was cut the dadoes all the way through the beams at a depth of 1/16". I then milled some 1/16" pear stock to the width I needed to give me stopped dadoes. These were glued in place and sanded smooth. Very easy!

I started work on the upper deck by rubber cementing the deck beam profile templates to a sheet of 3/8" swiss pear. I used the scroll saw to cut out the beams, and sanded them smooth. Each beam is 12 scale inches square in profile!
I cut the beams slightly long and used the disk sander to sneak up on the final width. I'd like them to fit with no side- to-side play, but the fact was that due to the tumblehome of the top timbers, I had to make the final beam length a little short so they could fit into their notches on the clamps. Any side-to-side play will be taken care of by using removable shims at each end at glue up. The photos show the beams resting in place. Partial beams #4 are not yet fitted.

I cut and notched the 4 planks that make up the upper deck clamps. After bending them to the slight aft narrowing they were glued in place and treenails added. Then I cut out the eight mortar pit support knees and pinned and glued them in place.

I'm working on cutting the mortises into the upper deck clamp today. Meanwhile, I laid out and installed the treenails in the mortar pit deck. I used a #61 bit and birch toothpicks!

I built the secondary mortar pit deck off the model by edge gluing the planking together. I then located where the center of the circular cutout would be and drilled a hole. I transferred this location to the primary deck by putting the deck back in place and marking the primary deck with a nail through the hole.
I whipped up a little jig to hold the secondary deck in place while I drilled out the circular recess with a Forstner bit. The secondary deck was glued in place.

After gluing the mortar pit support beams in place I began work on the mortar pit itself. The first parts to make were the boundary timbers that define the outboard boundary of the pit deck. These are swiss pear timbers with a rabbet ploughed into them to accept the secondary planking layer.
There a two layers of planking. The primary or lower layer is thick: about 9 scale inches. The secondary layer, which lays on top, is thinner and has a recess cut in it for the rotating platform the mortar sits on.
Holly can get mold growth which can stain it a bluish gray color if there is too long a delay between cutting the logs and kiln drying. I had a piece with that stain in it. Rather than chucking into the fire wood pile, I used it for the lower planking, since only the ends of the planks can be seen and they don't show the staining. The photos show the lower or primary mortar pit planking and the boundary timbers. Note the discoloration of the holly.

The next step is to cut out the mortar pit beams. These support the pit deck itself, and in turn, rest on the upper support beams of the shell room. There are notches (really shallow dadoes) for both on each beam.
I milled up some 3/8" thick swiss pear and glued the beam templates to the wood with rubber cement. They were then cut out using the scroll saw. The mortar pit boundary timbers fit in the dadoes on the upper surface of each beam (red arrows). It's important that these line up exactly so I cut the beams a little long and snuck up on the final length using the disk sander. There should be no side-to-side play in the beams when fitted properly. Then I cut the dadoes on the under surfaces of the beams (green arrows) after marking each one individually so the fit on the upper support beams is precise. The beams have poly but are not yet glued in place.

Work on the shell room continues. I made the upper support beams out of boxwood and the blocking timbers between them of pear. They're glued into place, but not poly'ed yet. Once that's done, I will individually fit each of the 6 mortar pit beams into their notches on the clamps.
