: I totally respect your views, and I concur.
: But, scharf joints have been used for many years on Home Built aircraft and
: have undergone many more times the tests and stresses that any kayak could
: ever go through. I know of two personally that used skin of 1/8"
: aircraft spruce scharfed with an 8 to 1 or 12 to 1 ratio, and both have
: flown in several flyins across country. There are many different aircraft
: from sport to stunt that use these joints. In most cases, these joints are
: much stronger than the actual wood they are constructed from. In tests
: useing Titebond and Resorsinal glues, these joints have been broken, but
: it was the wood that failed around the joint, and not the joint. I can't
: quote you any scientific studies, or anything professional, but, I have
: seen this done at EAA meetings by the members themselves. My father
: participated in one where two 2 x 4's were end glued and when set, put on
: two saw horses about 12' to 14' apart and one member stood on the joint.
: When he jumped up and down on the joint, it broke and was shown that the
: wood shattered and not the joint. This was done with a yellow glue. I
: would trust these joint. However, you can't trust just anyones joint. They
: have to be made right, and have full contact over the entire surface area,
: or they suffer in strength. Same as any glued joint that I know of.
