My name is Guy and this is my first post in this forum. I am here because I want to build a wooden drift boat and, undoubtedly, I will occasionally need advice of the pool of experts and experienced drift boat builders on this forum.
In preparation for this project I have read and studied three books: Drift Boats and River Dories by R. L. Fletcher, Boatbuilding with Plywood by G. L. Witt, and Covering Wooden Boats with Fiberglass by A. H. Vaitses. I have also developed my own set of construction plans based off of the "Original McKenzie Double-Ender with Transom" in Fletcher's book. I used and MS Excel spreadsheet to calculate all of the dimensions, cut angles, compound angles, and bevel angles of all frame components and I used Pilot3D software to calculate the as-cut dimensions of the plywood sides and bottom. At this point I am pretty comfortable with the mechanics of construction and I think that I am just about ready to start purchasing lumber.
Presently, I plan to use Meranti Hydro-Tek plywood; 1/4-in. on the sides and 1/2-in. on the bottom. I found plenty of places to purchase these materials, but they are all far away from Idaho Falls, Idaho, and as a result shipping costs more than the materials. Are any of you aware of a business within a few hundred miles of Idaho Falls that sells this plywood? I have a few requests in to the local lumber companies, but I have yet to talk with someone who has heard of this material before.
I also plan to use Port Orford Cedar (CVG) for the straight frame sections and White Oak (quater sawn) for the bent frame sections (chine logs and sheer rails).
Thank you, Guy
Martinac. Plan B. I originally thought I fill the old scarfs with fiberglass and epoxy. I tried one and it didn’t go well so I abandoned that plan. Instead I’m installing proper Dutchmen repairs. Once again I routered the scarfs, but this time with straight edges. Then I made patterns to cut the 1/4-inch plywood Dutchmen.
Martinac. One set of inside panels installed in the bow. Three more sets to go. I bed the panels in 3M 5200, not epoxy as I mentioned earlier. The panels are also secured with 1/4-20 silicon bronze machine screws that are recessed from the outside. Can’t tighten them too much else the heads will pull through the plywood. I’m not entirely satisfied with the situation, but I’ll just keep moving forward.
Martinac. I’m curtailing work on the Martinac’s hull until next spring. I cleaned and organized the work area around the Martinac and moved many tools and supplies back to my garage at home. This winter I’ll focus my attentions back to the Chris Craft. But I will also start working on the Martinac’s engine. Here I’m cleaning the raw water pump. Like the transmission, the water pump is also obsolete. I hope these obsolete components have a little more life in them. A new engine and transmission for the Martinac would cost about $14k.
