In the books it says that for initial assembly, canoes should skip the gunwales and use the next stringer down to set the frames and etc. On the Crawfish, the next stringers down that are full length are the ones at the chine. Should I just go ahead and clamp a cross-brace to every frame and use the gunwales for this step?
I am seeking a little assistance with alignment of the butterfly on a Flyfisher 13' canoe. Assistance provided by Graham(designer)
I have marked and cut the bottom according to the Cut out Sheet (metric) and have an A- B line of 0.411m with the angle BAB of 78deg.
I have marked the side / bow according to the Cut out Sheet (metric) and have an A-B line of 0.401. There was a small typo on the metric plan
I have double checked all measurements and even calculated the lengths and angles to verify.
Is this correct that the AB straights on the bottom and sides should be of different lengths? No
Assuming this is correct
1- if I align the AB edges at A the side will be out by around 6mm and the butterfly will cross the LCL extension line all the way from A to C
2- if I align the AB edges at B the side looks good but the butterfly will cross the LCL extension line 12cm from A on the A to C line.
This will cause the sections to overlap when doing the tape and epoxy butt join.
Is 2 what is intended?
I am unable to (quote from plan page Hull assembly) "" Position the A-B straight of the side/bow against the A-B of the bottom so that the straight A-C line of the bow section falls on the extension of the bottom LCL" I believe that to achieve this either the bow 39deg or side/bow 143 deg angle would have to be reduced. With new measurement provided it all lines up perfectly
Please help, any and all assistance greatly appreciated.
Will post photos when done
Well, I finally got around to starting my first boat. I hope that this is just the first. I want to build a Core Sound. I have moved to a place that gets cold in the winter (Idaho from Florida). So, I hope to get this boat or at least most of it done before it gets to cold to work outside. Sorry about the picture quality. I was too lazy to go get a real camera and shot these with my phone. I will not do that again.
Graham, building the Diva reminds me of the months working with you. Even the smell of epoxy brings back fond memories. I did get Brian involved when I folded the boat and tied in the bulkheads. I hope your cleanup is coming along. I wish that I could be there to help.
