Uncle Frosty Posted September 14, 2015 Report Share Posted September 14, 2015 Finished the frame of my Crawfish. I painted it brown to cover up the mistakes and so the dark frame will show through the translucent skin. Now I need to cover the mistakes I made while painting...drip city. 1 Quote Link to comment Share on other sites More sharing options...

Uncle Frosty Posted September 16, 2015 Author Report Share Posted September 16, 2015 Thanks Woodman. I had seen your pictures before starting my build and found you work very inspiring. Love you Stonefly. Wish I had you skills. Quote Link to comment Share on other sites More sharing options...

woodman Posted September 17, 2015 Report Share Posted September 17, 2015 Looking forward to seeing it with fabric.... The hull is a little different than the one I did.....https://www.flickr.com/photos/mo_kayaks/8285713429/in/album-72157632283284724/ Quote Link to comment Share on other sites More sharing options...
Abyssdncr Posted August 15, 2016 Report Share Posted August 15, 2016 Alright, I know this is resurrecting an old thread, but Woodman, are the pics on your Flickr account a rendition of the Crawfish design, or a different pirogue altogether? Thanks! Quote Link to comment Share on other sites More sharing options...
woodman Posted August 15, 2016 Report Share Posted August 15, 2016 A different design .....It was a stitch and glue plan I converted...... Quote Link to comment Share on other sites More sharing options...

Sobrevida Posted May 26, 2018 Report Share Posted May 26, 2018 It looks like you have a stringer that runs on the inside. Was that part of the plans or a modification? Quote Link to comment Share on other sites More sharing options...
Sobrevida Posted May 26, 2018 Report Share Posted May 26, 2018 One more...sorry...it looks like you ended that lower stringer BEFORE the 2nd frame. If I read the book right, is it supposed to meet before or after? While lofting, I noticed there is little room to cut notches in the 2nd frame, so your way would seem to solve my concern. thanks again!

even-keeled Posted May 26, 2018 Report Share Posted May 26, 2018 The stringer on the inside is the seat support. The dimensions are shown nearby in the book. I plan to only use that support at seat locations. The offset chart shows the short stringers attached to the second frame from each end, sketch below. I'm not sure if it would be practical or necessary to attach them to the center stringer. Quote Link to comment Share on other sites More sharing options...
Sobrevida Posted May 28, 2018 Report Share Posted May 28, 2018 even-keeled..thanks for the reply. When I did the original lofting, I was concerned because there are a lot of stringers converging in a little space, and I was worried that the plywood wouldn't be strong enough. Then I saw Uncle Frosty's pictures and it looks like he just tied the stringers to the keel before they reached that second frame... so now I don't know what to do.....

even-keeled Posted May 29, 2018 Report Share Posted May 29, 2018 While it would probably be fine either way, my experience with structure says to not end main structure adjacent to other main structure. As built in the FROG photo here, any stress between the center three stringers and the second frame from each end will mostly be concentrated on that 1 or 2 inches of center stringer where all those parts meet. If the short stringers get lashed to the 2nd frame as designed then the stress is more evenly distributed. After the short stringers pass through the second frame, I would radius the stringer ends so they lift off of the skin. If you're using 1/2" Baltic Birch plywood and lofted per the plan, it should work out well. I tend to overthink solutions like this but I've been happy with my results.

Sobrevida Posted June 10, 2018 Report Share Posted June 10, 2018 Thanks again. That makes a lot of sense. And if I had to choose between over thinking and under thinking, I'd choose over! 1 Quote Link to comment Share on other sites More sharing options...

Yes! Or even taper the top edge of the end of the string down half way, a more exaggerated version of even-keeled's suggestion. I did this on the deck stringers of my Ravenswood and the 2nd Curlew I built, worked very well and you avoid a bump in the skin. Quote Link to comment Share on other sites More sharing options...
even-keeled Posted June 11, 2018 Report Share Posted June 11, 2018 Yes, and these photos show a version of this this technique at the deck stringer. https://messing-about.com/forums/topic/10281-southern-hemisphere-curlew-frog/?tab=comments#comment-97779 Quote Link to comment Share on other sites More sharing options...
