Fortunately we keep our house fairly well controlled in terms of temperature and humidity so I'm hoping that there is minimal dimensional changes going on here! For this project I will make use of the dimensions listed in the monograph as well as the plans. I had read about your use of Mylar in your books and it may be wise for me to think in this direction for future projects. This certainly seems to be a situation where it would be valuable to have CAD files which don't appear to be available for ANCRE publications. But I do have a project in the wings that needs to be done in the next couple of years for a local non-profit. They want I model of a Mackinaw boat and I have agreed to make one for them. Still not sure what draught I will work from, but it appears that I will need to draw the plans myself - it could be a good introduction for me for working with Mylar. I am very much looking forward to seeing the result of your current project; South Carolina (ex L'Indien?) is such a beautiful frigate! Greg -
Magnificent!

Before refining the joints, the accumulated error in length of the keel was nearly 2mm over the ~80mm unit. After working more on the joints, I've reduced this to less than 0.5 mm; so I'm now within 0.6% of the plans. I concerned that if I go further, I may end up being off by more in the negative side / am I already in the area of contraction / expansion of the paper plans - what to do now? Here's what the 4 scarf joints that link the 5 pieces of the keel from fore to aft: Next up some work on the false keel joints
-
Milled the scarf joints and set the pieces all together: Now they need to come back to my model room and get a little bit of final fitting!
-
Finally all these parts have been milled to their proper dimensions (two pieces I didn't like my first attempt and remade them) - time to start in on the scarf joints! Hopefully milling of the the joints go well so that this step doesn't need anymore redo's.
-
I'm glad you like what you are seeing here. I got a chance to see the work you have been doing as well - very impressive! All the best, Greg
-
After 'tuning-up' the mill a bit, I got a start on fabricating parts for the keel and false keel. I cut out paper templates that were quite wide in comparison to the parts in order to maximize my chances of keeping these long straight pieces nice and straight.
-
Here are all the full frames together - I think there is an unwritten rule that they need to be stacked up and photographed at this point:
-
Thanks for dropping in, the complement, and for making your very nice build known to me! Greg
-
Here are the last 4 full frames glued up and drying between glass plates. Time to build a keel to set the 55 full frames on!
-
A bit more progress - two more sheets of parts to cut out and I will have 180 pieces needed to assemble frames 43 thru 57. The three sheets of wood in the foreground are 5.35mm thick - they are for the next phase: the keel structure.
-
Most of the parts for frames 43- 50 are ready to cut out. Blanks for the two part floors are between glass plates drying flat. Photocopied patterns for all the parts for frames 51 - 57 are in the plastic tray ready to be rubber cemented to wood. I feel I'm getting rather proficient with the frame assembly line! Looks like I also need to prepare a bit more 4mm thick material for the last 7 full frames - not going to make it with what I've already milled.
-
Frames 2 - 8 assembled. So frames 2 - 42 have been put together. I've made (a lot of) photocopies and am preently cutting out the patterns for the remaining full frame.
-
Good deal of time at the scroll saw, followed by trimming ends on the Byrnes table saw, and milling of the slots for attaching to keel. So now I have a 'kit' for frames 2 - 8 to assemble! I think 3 or 4 frames fit between my glass sheets for drying, so 2 - 3 days of work with these. Simultaneously, I can start building a kit for Type C frames 43 - 57. After that, it looks like I better get at the keel structure and make a building board / cradle for L' Invention. I am really looking forward to seeing the frames standing up in order giving a first impression of the hull shape!
-
First batch of Type C frame pieces are ready to go to the scroll saw. These pieces will make up frames 2 to 8; the remaining C frames are 43 - 57. Once done, I believe that will be all of the full frames - 56 in total.
-
I know it has been quite a while - much longer than expected! The 'quick diversion' of building the Santos-Dumont 14bis turned into researching and building a model of the Santos-Dumont No 18 Hydroplane. But that is done and today I got out the Swiss Pear and started to mill enough wood to finish the remaining frames. Looking forward to making frames and then a keel structure to place them on!
-
First, I want to say thank you to everyone that spent time following this build and an especially big thanks for all that provided me with their views and information that I would not have otherwise been knowledgeable of. Second, I have gotten back home from an enjoyable couple of days at the 48th Midwestern Model Ship and Boat Competition. This morning, I was quite satisfied to see the model had earned a gold award in the advanced category; but later in the day, things got even better when it was announced that the Santos-Dumont No 18 Hydroplane had been judged as Best of Show!

The model mounted on a display board now. I'm not sure I will add more to the model at this point; however, if 'new' information appears I am not opposed to modifying what has been done to this point. Friday the Santos-Dumont No 18 hydroplane will get a ride to the 48th Annual Midwestern Model Ship and Boat Contest. Very interested in what kind of feedback I will receive - hope it is liked!

All ignition wires are in place and I believe I have done what I can wrt the engine. All the woodwork for the case has been completed. Staining / finishing and then model installation followed by a couple of final details; however, for the most part I think I'm close to a finished (for now) situation.

As I went to the other side, more boots went missing so I ordered more as a safety measure - it must of worked because a got 16 in place and have one left over before receiving the extras! I've wired one side based on the following picture: Here's the result: Time to turn the boat around and complete the wiring.

Rigging is done (as far as it's going to be!). So on to the ignition harness. Trying to install resin spark plug boots; they're a bit of a challenge for me and I've lost two to my gray floor so far - lucky I ordered 20, 8 on -2 lost is a ratio that will work. The boots are made by Pro Tech and are marketed for 1/25 scale model cars.

Even tighter now! Added the engine pylon bracing and backstays: Two more lines to go; the one's that go from engine pylon to aft part of the nacelles. Then onto the ignition harness to finish what I plan to do on the engine.

I need to keep reminding myself that his contraptions were almost always in flux and that he seemed to like having pictures taken with his work no matter the stage of construction. Combine this with him taking parts from one project to put on another and then possibly modifing after in place makes using the photographic evidence so much fun!

What is the conical structure behind the pilot seat on the No20? Could that be fuel and the double cone on top just coolant? I like the radiator piping along the wing panels!
