Thanks everyone for your post. I think the flattened PVC pipe will be strong
enough just needs to hold each section together.I have made several PVC bows and they are surprisingly strong plus will probably use more than I need just to make it look cool. I caulked the seams and screwed it together. I tried to weld it but at the time couldn't get it to work, so with the wonders of youtube a may research it and try again, would be great if I could weld it. I want to some day build a big voyager canoe like 6' wide and 24' long.
I'm not worried about it solar degrading because I will keep it in a shed with all my other plastic kayaks. We plan to move to southern Mo. where there are a lot of clear rivers, I like the smaller kayaks better than those 16 ft. canoes, this one is just over 10' if I remember right. The bigger canoes are great if you have a lot of cargo.
Don't forget to check out my youtube video,
should be a link up top. I will also be doing some survival videos and building a homestead where I want to build historic type buildings like log cabins and
cob, developing a spring and building
cob ovens and such. Also want to do some caving videos.
Thanks again for your input, God bless and have a good day.
