Wawona59 Posted July 4 #62 Posted July 4 Fantastic Greg! I learned a lot following your techniques for making the different sized hoops. Looks like you've got a Alberto Santos-Dumond theme going. You might enjoy the book "Wings of Madness" about Dumont and some of his projects and eccentricities, like his 8ft tall dining table so guests could dine in the sky. I'll be following your project with great interest.

I'll be following your project with great interest. John John - I'm glad that you are interested in the project and I really appreciate your support. Noting your list of builds (and location) I have a Slo-Mo-Shun kit waiting in the wings - last year I was out to Seattle to visit my son and we went to the Hydroplane Museum in Kent to see some of the classic hydroplanes and then saw Slo-Mo-Shun IV in the museum near Lake Union in Seattle. Such a cool boat! I have obtained and read the book "Wings of Madness" as part of the background research for this project. It is certainly an entertaining book and I learned a good deal from it; however, I was really disappointed when noting that the author did not seam to understand that the No 18 Hydroplane was actually a watercraft / boat as opposed to an aircraft that could take off / land on water.

Greg Davis Posted July 11 Author #65 Posted July 11 I now have one nacelle nearly done - it still needs the cross bracing wires to be added. Constructing the nacelle has been more work than expected. The main pontoon was quite a bit easier for me, probably due to the larger size of the hoops. Nevertheless, progress is being made; hopefully the second nacelle will be easier given the experience of making the first one. After I had added the hoops I didn't like the envelope of the nacelle. The middle hoop was a little too small in diameter to present a nice outline. I made a set of middle hoops, increasing the diameter by 1.5mm, and now the shape looks good to me. When making the new set of hoops today, I tried out an alternate method for making a hoop. This time, on a lathe, I turned the hoop out of a solid piece of wood. First the exterior diameter was turned and then the interior was cut out before parting off the hoops. This method doesn't take much time at all to make very well dimensioned hoops that seem quite strong. The resulting hoops don't look bad at all, but I think that the laid up ones look better due to the grain direction and are probably closer to the way Santos-Dumont had manufactured the ones for his boat.

Greg Davis Posted July 15 Author #66 Posted July 15 The second nacelle has been going together quite well. Waiting for tip filler blocks to dry so that I can form the two ends of the second nacelle. After that the cross-bracing will go in both. Got a new shop addition also - a larger stand alone router table. Still need to add a safety switch before using. Looking forward to using it for case fabrication among other projects! Ryland Craze, AON, GrandpaPhil and 2 others 5 Quote
Greg Davis Posted July 15 Author #67 Posted July 15 Here are the nacelles by the pontoon. Presently deciding if I should build the engine support / pylon next or if I should work on the nacelle / pontoon attachments. mtaylor, AON, GrandpaPhil and 4 others 7 Quote
Greg Davis Posted August 29 Author #68 Posted August 29 Decided to give a go on the hydrofoils today. I cut a piece of boxwood 1/4" thick, a bit wider than the chord (~ 2cm), and about 2 feet long. The main hydrofoil is about 15" long the rear one about 4". After marking the foil shape on one end of the slat, I repeatedly ran it across my table saw to 'mill' the basic shape. The extra width of the slat allows the slat to sit flat on the table saw for this operation. Now I will sand the final foil shape, except for the leading and trailing edges - they will be shaped after parting the mostly formed hydrofoil from the extra material. I hope this works!

Greg Davis Posted August 30 Author #69 Posted August 30 A couple of Dremel flap sanders later and some finish sanding has resulted in some good looking hydrofoils. Here is a mock up with the pontoon and nacelles. Now I really need to do some metal work! yvesvidal, AON, ccoyle and 5 others 8 Quote
KeithAug Posted August 30 #70 Posted August 30 All looking very good Greg. I remember some years ago viewing an early hydrofoil developed by Alexander Graham Bell in Baddeck Nova Scotia. Its wasn't quite as elegant as your replica but would make an interesting model. I particularly liked the Venetian Blinds foils.
