Skin for Blanik wing

Just a quick update on this: I've arranged to obtain a coupon of wing
skin material from a local L-13 wreck, and arranged for a lab to do a
chemical assay to identify the primary alloy components. I'll also do
a static pull with my tensile test machine to get basic physical
properties.

Thanks, Bob K.

Thanks Bob !

PS: Are you going to do an analysis of the rivets as well ?
Composition, taper, hardness, etc ? For the hopelessly
curious...

Dave, I'm not going to do that at this time. The wreck that I'm
getting the skin sample from doesn't have any riveted parts that are
so badly smunched that their removal would have zero impact.

If somebody out there does have a bit of flush-riveted Blanik wing
wreckage, I'd be glad to cross-section a couple of the rivets so we
can get an idea of the joint geometry.

Thanks, Bob K.
