Hello all,
Im building the Flats Flyer currently and I am at the stage where I need to start adding the sheer clamps and Chine logs. This is a 19'8" boat. Probally a dumb question but I'll ask any way. Do the Chine logs and Sheer Clamps need to be made from solid 20' strips, or can I make them out of 10' strips? If so how do I join the 10' strips?
Thanks for the help!
Adam

Hi Adam,

The chine, sheer and batten pieces need to be continuous.. but you can use 2 smaller pieces and join them together to make the size. There are few kinds of joints... scarf.. butt.. lamination. I used the scarf method for my chines and lamination method for my sheers.

The Glen-L Boatbuilding with Plywood book was really helpful in describing the process of creating the joints.. and there are several here on the Glen-L forum you can search as well as the web.

Hey Iggy I have seen a bunch of posts mentioning lamination for the joints. Can you explain it a bit more for me?

I get how you can laminate pieces like the stem together but how do you do it to join 2 shorter pieces?

Adam.
I made a jig for my circular saw to cut the oak at a sharp angle to make the scarf joint.

A sliding miter saw, or jig on a table saw can also be used.
This creates a cut like this:


So, if you do this to two 10' pieces, you can epoxy them together and get one long piece.
This shows the joint on two chine logs. The circles are where I used a nail gun to hold the pieces in alignment while I clamped them.


It is best to have the joint in a section of the chine/sheer that isn't getting stressed a lot.

That was actually a really old post I found, I was just curious what Iggy was talking about there and I see he still posts frequently so I responded on the old post to ask.

I haven't actually done this yet (or anything else on my build as far as wood work goes) but I believe what Iggy was talking about was several strips of shorter length laminated in such a fashion that the joints are offset from each other. Something like the attached drawing.

what you showed is a butt joint the scarf joint is stronger and doesn't require a backer board but what you showed is correct for a butt joint. I can't find a good picture of my lame beams a made. basically you cut your two pieces on a sharp angle then epoxy them to gather also when they was refereeing to staggering the joints i believe they meant for the pieces at opposite side of the boat also this joint should be mounted so that they fall in a area that don't have any bends in it or very little when you make this joint it makes it stiff so it won't bend as easy and could cause you to have a flat spot or break on you. defiantly on a butt joint you don't want it on any curve. my 2 cents
