I just found this Forum the past week and was pleased to see all the interesting discussions. I have previously (2006) built and launched a 16 ft. Peterborough Stripper from Tom Moore's original Canoecraft. The Bear Mountain Boats Forum was a wealth of information, as I had not built anything from wood that was expected to float, in water. The stripper was a lot of fun to build.
About a year later I discovered/purchased Roger Fletcher's book and decided to make a go of it and build a drift boat. Last April I laid out all the framing on poster board full scale. I am a retired Mfg. Engineer with 41 yrs in the Machine tool and Automotive Industry with lots of hrs. Hanging over a drafting table. After making the decision to build I spent many hours deciding materials, features etc.
I have 210 BF of White Ash from a couple of trees infected with the Emerald Ash Bore (big issue in Mid-Mich). So the framing is Ash (3/4" x 3.00"). I finished the last one in December. I just need to coat them with epoxy (been waiting for 60 degree temps). The frames are constructed using Half-lap joints. I discussed this in 2011 with Jim Watson of Gougeon Brothers and he offered their services in testing the joint strength (they have a MTS Tensile Test Machine w/ 100K Load Cell). I just received the results and test pieces a couple of weeks ago and will post them soon in this discussion. (I need to figure out how to post pictures here.)
The Stem blank is solid Ash. I just finished the transom a couple of weeks ago. It was made from African mahogany. The sides are going to be 1/4 x 7/8" WRC w/bead & cove. I have a couple of planks left over from the canoe. The sides will be encapsulated in 6 oz. glass and West System 105-207 Epoxy prior to being fastened to the frame. The bottom of the boat will be "cold molded" ash at 1/4 x 2 1/4" in two layers one oriented Fore Aft and the other 90 degrees to the first. Planning to add graphite to epoxy on the bottom.
Next work is to build a strong back and begin assembling the framing. Am looking foreword to your comments and assistance.
Thanks for being here.
