It took longer than intended to get back to this but I have. In this photo below you see that each level rises and also rolls outboard. These dimensions are all different at each level. I made outboard guides to rest my beams against. These have been PVA glued with a dot of glue on to my side counter timbers so they can easily be removed later. This are made in soft pine so if anything should break off it will be the pine. I rubber cemented cardboard on the inside lip of the wing transom to act as a stop and hold the foot of the counter timbers from sliding inboard. I also rubber cemented a cardboard ledge protruding slightly inboard on the upper deck outboard support onto which the step in the timber can rest (you will see this later... baby steps). The underside of this piece has a radius upwards as the steps will rise with their relative position. I will first make/fit cardboard templates in position to prove them. Then I will cut and fit the timbers in place...and build it up. Once I have it done I can make the inside beams to suit. With things going on in my life presently it might take a couple weeks. All this might seem like a bit much but as I could not visualize the assembly to identify my problem this seemed a logical move to help me. I believe building it up and on the model will assure it is all correct. Which brings me to my original problem that brought me here in the first place. I discovered with this process that I had transposed the up/out radii of the Roundhouse beam that interlocks with the counter timber tops. This caused the timbers to lean inwards at the top, pulling the timber foot out and off the wing transom. The dimensions don't seem like much at 1:64 scale but the moment arm or twist over the distance certainly was. That mystery solved!

Here is my problem... The transom is rounded horizontally (out the stern) at different radii at various elevations, and also vertically (height), just to complicate things. There is also a step in the outer side counter timber that becomes less deep as you approach the centre beam at which point it disappears completely. I have my paper templates for the shapes but they just do not seem to fit into place when cut out in wood. If I get them located properly out the back they do not reach the wing transom. I'll get nothing done this weekend, too many other things planned. Next week I will have to make mock ups (cardboard and wood) to fit and better visualise the different pieces. Once I can do this I can make them.

That is terrible news. Dumb question- if you wear a patch over the bad eye will the eye strain (headache) disappear? I know for me the brain does wonders melding the images from both eyes. Possibly that is your next battle, removing the one blurry image from what the brain has to deal with. Of course I am no doctor so this might be something to discuss with yours. -

Have you seen an eye doctor? I get an injection in my left eye every 9 weeks for going on 5 years now for one problem, and just had cataract surgery in both eyes last year. If it weren't for my regular eye checkups I'd be blind permanently in the left eye and going ( but reversible) blind in the right by now. As it is I now have 20/20 vision in both eyes except for a tiny spot just off centre at about 7:00 that is white if reading type (books) when I am tired, otherwise the other eye fills in the blank. -
I buy my wood in billets (about 4" x 6" x 6 feet) Cut them to about 18" in length on my table saw. Cut those small slugs into slices length wise (thicker than what I needed). Pass these through my 13" thickness planer to get them flat on both sides. Pass those through the Byrnes model Machine thickness sander to get the required thickness. Cut my pieces from that with a Byrnes Model Machine Table Saw and/or my 16" scroll saw.

I spent a considerable amount of afternoons this week working and reworking the stern timbers and beams to close it up. When I came up today the wife asked: "how did it go?", and I responded: "I learnt so much today", and she said: "what went wrong?" There's no pulling the wool over her eyes. No photos until I master this part... or at least earn an "atta boy".

Roundhouse and quarterdeck clamps installed each in one length. Steamed and clamped the forecastle clamps. They formed up quite nicely with twist and camber but the knuckle doesn't set against the hull so I will do them again with more clamps. I had propped them out at the bow with a spacer to accommodate spring back and that seemed to work for the most part. Speaking of (spring) clamps to hold the wood strip deck clamps to the hull. All mine are quite short and lack the reach needed for the upper deck at the bow and stern, the gun deck and the orlop deck (if I'm putting this in). I could make something to reach through the gun port which takes care of 80% of the clamping needs but what about the rest, and the orlop deck has no gunports to reach through. I found a YouTube video by an airplane modeler (key words for your search are "elastic band operated clamps") and decided to make a couple and see how they work. Once set they do not open one iota. I made a few modifications to how the elastic connects, the bar stop assembly and the clamp nose piece assembly (cotter pins) and my dowels are dry friction fitted so the whole thing can come apart if needed. They are made of hemlock with pine nose pieces and maple dowels. Extremely light and as they are a soft wood, if they topple over nothing gets damaged. I estimated worst case I needed a 6" reach and they provide 8-1/2". Now I'll likely make a couple narrower ones for nesting closer together, and a few much smaller to reach through the gunports.

Hello Alex. I am not aware of your location but if it will be of any help I have some photos of the Brig Niagara. I was on the replica for a day cruise and banged my head quite a few times when down below. She was quite shallow because of the sand bar entering or exiting the bay in which she was built. Even at that they had to remove the guns to lighten her up more to clear and the British were there waiting but didn't realize she had no guns so didn't attack. You might want to correct the spelling of the ship's name in the title... you're missing a letter. -
All fixed. Decided not to take the over thickness starboard clamp off as the alcohol to do this would de-glue the frame and chock connections behind it. I sanded the port roundhouse clamp to the proper thickness and used it to mark off the proper thickness of the starboard clamp that was glued in place. I then sanded it down to below the line, this taking into account the thickness of the pencil line outside the thickness of the clamp used as a template. At this time both are attached. Today I made stock for the quarter deck and forecastle clamps and they will be installed next.

The Roundhouse Clamps have been made, steamed and bent to fit. The starboard side has been glued and clamped in place. In the photo below you can see my form used to shape the clamps to. The port side clamp is on the table next to it. I've started the Quarter Deck and Forecastle Clamps at 4" x 12". 4 inches thick seems awfully thin compared to the Roundhouse clamps at 11" x 13" but that is what they are. ***EDIT: I made a major boo boo. The size of the Roundhouse clamps didn't make sense compared to the Quarter Deck clamps. I then looked at the Gun Deck and Orlop deck. I checked the image in the Bellona book. I went back to the original contract document. The 11 is actually a 4. The way it is written it looks like an 11 to me. Now I have to try to get the one off and do it all over. My sailor words are creeping up through my throat from my gut. Also, I received my resin printed carronades just over a week ago and they look fantastic! 8 each x 18 Pdrs and 2 each x 32 Pdrs. The larger is about 1" long and the smaller about 13/16" long I have no idea why I waited a week to post this other then they are very delicate (screw nut handles) and I don't want to handle them more than necessary. I'll get them painted and stored away in the next few days.

I'm starting with the roundhouse clamps at 11" thick and 13" broad (height). Clamps were normally 25 to 30 feet long but I read the roundhouse clamps were normally made in one piece. Mine are about 49 feet long. That would be a beast to lift in place at practically 1 ton of weight. I made a quick mock up out of scrap poplar, marked off the heights for the clamps and laid the mock up in to check it out. It ran below the top of the door opening. Double checked my pencilled in door locations which were spot on. I found that the original framing plan had the round house deck beams drawn in at double thickness. After adjusting things the mock up just cleared. I then made up the two clamps in Castello boxwood, a paper template of the wall curvature, and then a form to clamp my steamed clamps to. When dried I had 1/8" spring back. Adjusted the form and things are re-steamed, clamped and setting now.

Will this be the master for casting more?

Rebuilt the side quarter and faired (sanded). Looking considerably better this time. I installed a temporary brace across the top of the counter timbers to try to steady things a bit while I work in that area. Marked of the top timbers and quarter doorways. These will be cut down/out this weekend, then I'll get the cills installed. I am hoping to do a better job on them also!
