Thanks everyone for the wonderfully encouraging comments and likes. In order to capture the rods I decided that a handle could act as both the means to rotate from the inside and also act as the capture. First a disk of 1/2 inch brass was turned down to 3/16 for about 1/8 (1") and two holes .031" x .030" deep to match the pins were drilled and a clearance hole through the centre for a countersunk 00x 90 machine screw. then it was parted off the bar. This was positioned onto the rear side of the spindle and the position marked for the full extension of the rods with a sharpie. Next the surplus was removed with the jewelers saw. and was then filed and polished to the final shape. the door plate was pinned into position prior to placing the door knob. then placed into the opening to check size. The rods are cut to their final length. and the outside Now for some supper. Michael

For the lock I have decided on a variation of the crash bar type rodding. First a handle spindle was turned up from some 1/4 inch brass rod and stepped down to 1/16 at the handle end then 3/32 for the section that coes through the door frame and finally 3/16 for the cam section. A separate door knob was bored out to slide over the 1/16 end. The spindle was then pushed into place and transferred to the mill for drilling the hole for the taper pin to hold the handle on. Then using the taper reamer for the third smallest pin the pin will get cut to length later. A .020 plate was cut and drilled for the door plate and the cam side was set into the door frame .030" The pins in the cam disk are taper pins that have been driven home with the tiny hammer and cleaned off. some bars of 1/32 x 1/16 were drilled out to fit over the .023" pins Next some capture plates were folded up out of some .010" using the vice as a press after punching some .020 holes and a little rough shaping it looks like it will work. I might make some cleaner ones tomorrow. and figure out the handle for the inside which will also capture the bars Ah yes then some more hinges. Michael

The beveled, panels looked a bit heavy so opted for a different style. I planed up some thinner panels and put a bevel into the stiles and rails. Now I need to sort out a locking mechanism. Michael

Hello Doris I was saddened to hear of the loss of your Husband. Your Tribute to him is beautiful. I would think that as you have mentioned how much he loved and supported your work Work is not the right word Your Art your ability to turn humble materials into magnificent models is unparalleled. That your Husband will be championing you in spirit and guiding your next model choice when the time is right. Thank you for sharing your Art and superior craftsmanship with us to enjoy. Sincerely Michael

Thanks Pat, and to everyone for registering a nod with the like button. I keep thinking I should have made a lot more hinges when I was making them earlier. Also one of the troubles with Cad is that it took me ages to discover what the problem was with getting an accurate drawing of the doors to the companionway. Cad is much too accurate! I was taking measurements and putting them into the drawing, and then the next measurements were conflicting, and things seemed to be mismatching. I even set up a sting datum line from stem to stern to double check the details of the cockpit and companionway, Printed out the doors cut them out and they did not fit cleanly. Went back did more and different measurements, printed it out again, another different slight mismatch. Then I discovered that the deck is 3/64ths lower on the port side than the starboard and that there is a 1/32nd parallelogram to the companionway relative to the deck. A final adjustment to the drawing "as built" Ah then it fit. Then I was able to prepare the wood for the doors. The rough elements still a lot to do shaping the panels, but at least some progress after a frustrating morning drawing. Michael

Hi Mark Just catching up Glad to see that you are back working on the ship. I had missed your earlier troubles so am happy to hear that your health issue is receding into the past. And that you are moving forward with the planking. As has already been stated our focus on our model work is a great healing power. Michael

and welcome for the other side of the country as well, nice looking pup. Michael

Thanks for the comments and likes, The are encouraging. As the work continues with the refit of the cockpit cum companionway. I needed to add enough wood to create the jams for the doors I cut up some small strips with the jewelers saw, it seems to be just as fast as setting up the table saw and wastes far less wood, and I am loath to waste Mahogany anyway. A couple of strokes with the Veritas low angle block plane on the thicknessing jig to prepare them for gluing. A stop was added after the filler pieces had been glued. I still need to add the piece across the bottom, and then I noticed that the back beam across the hatch was going to interfere with the top of the doors so out with the alcohol. Reposition the part after a bit of clean up. Now the stage it set for the doors. Yes I noticed the scratch and the misaligned screws. Michael

Good to see that you are back to your build Mati, sometimes these things take a back seat to other projects. Michael -
Hi Eric just signed up I am really looking forward to your presentation. Michael

The rebuild of the companionway is starting to come together. The walls are a sandwich of Maple and Mahogany with an Apple cap rail. The companionway will go back to having doors like these ones. Michael

Hi Chris thank you for the change to the title, certainly makes it more clear. As I mentioned at the top this is in essence a future build with the need for Photographs that I can legally have access to for the development of this model. The actual boat is in the Long Island Maritime Museum, I have sent them an email regarding digital membership. The drawings that are in the Merwin Thesis were credited to Thomas et al. If there are any members who are knowledgeable in this area I am all ears. Thanks Michael

Very nice use of lateral thinking to accomplish a delicate bit of machining, Eberhard. Michael

Thanks to Keith Black for directing me to this post which references Gill Smith's work. Michael
-
Yes thanks Druxey a good idea, I will do that. All further references to the cat boat can now be posted here Michael
-
This is the new project that has to be fully researched yet. There is some cursory information for this model in the Thesis by Daria Elizabeth Merwin pages 57-65 I will add information as it comes together before the build starts.
-
Keith, thanks for this information. I am guessing that the Merwin Thesis that was submitted to the Office of Graduate studies is likely not published for general distribution. I am going to open a new thread about this boat as a start so that any research materials and references can be discussed there. Michael

The document I used for my tracing of Pauline's hull lines is this one. I would love to get a hard copy of this thesis. Michael

The first picture looks correct from a gear meshing point of view, I am not sure what the problem is? Michael -
Or daft depending on which school of Design one subscribes to. The reason of course is that if I had known back in 2012 what I current know (a little more) I would have designed the cockpit and deck openings differently. Because this model is not of a particular vessel but a combination of ideas from the type along with the current ideas of modern yachts being built as recreational boats for the pleasure of those with deep enough pockets, but alluding to the traditional working craft of the previous centuries. Basically this model is my apprenticeship for plank on frame model boats and rigging. My next model sailboat is likely going to be a Gill Smith catboat which will be an accurate model This is my tracing of a drawing from a book. That will need to wait though I still have a few things to learn and a trip down east to see the gill smith boats that are in a museum. once all the Covid issues are sorted. The Cat boats have such a beautiful and simple rig. back in 1970's I cannot remember the year I made a half model of a cat boat from a drawing that was in a scan from an early issue of Rudder that a friend send me. The future looks exciting. Michael

Bob, so I'm guessing that Stirling and Sons would have probably not have liked your comment. That said they could have been cleverly disguised latch handles that needed a slight twist to open them, by having the top rotate a 1/2 inch or less sort of like a lever type handle only vertical. Michael

Nice work on fitting the Garboard plank Vaddoc. Michael
