Hi Sean, You are in bad luck. I understand were you foundation your cracks. Check on my site at THE page extending fuselage. There you Will see hoe we did extending THE hole aft de tai of the boat. I think you can take onebay of THE bottum out and one on The side. Now you can splice you longaron. Maybey you can only take the crack out and do not cut The hole longaron. Chamfer THE damage earea to 1 / 20 , and put a new pece of wood in it.
Good luck Stef Stef and Ted are building the KR-2S see http://www.masttotaalconcept.nl/kr2 -----Oorspronkelijk bericht----- Van: krnet-boun...@mylist.net namens sean duggan Verzonden: di 19-7-2011 5:14 Aan: kr...@mylist.net Onderwerp: KR> Progress Report & Another Cracked Longeron Story It's good to see some progress being made by fellow builders. I'd like to contribute to the progress reports with my update. Today I managed to flip the "boat," and unfortunately, I will be adding to the list of cracked longeron stories : (. Upon inspection of my boat structure, I found 5 cracks! Two cracks in one longeron and one in each of the rest. They all reside in the bay directly behind the aft spar. I already knew that this could be an issue after seeing the problems run into by other builders. The cracks in the upper longerons seem reasonable to repair, a splice joint like the one shown in Darren Crompton's build log should fix the problem. It is the lower longerons that have me worried. Since the lower longerons are already glued on two sides to plywood, I have no idea how I will cut out a section for replacement. Also, the area that these cracks occur are in close proximity to a vertical stiffener. Too close to get the proper splice length. So at this point what are my options? -Attempt repairs and hope for some luck on the bottom longerons? -Cut my losses and start a new boat. (I've only used about $900 worth of wood and glue and spent 100hrs building)? -Look for someone selling a boat, toss mine and continue forward... Any suggestions/comments would be appreciated. My motivation is dwindling. Some photos are updated on my site. Thanks!
