Has anyone heard of Dick Johnson's wing flattening jig? I'm interested
in a Discus A and the owner said that this glider has had the wings
flattened. A previous owner of this glider was Wil Schuemann so mabey
he did the work. Anyone have more information about a wing flattening
jig and if it yielded any performance increase?

You may be thinking of the Johnson wing waviness measuring tool. It's
a 3 contact point base with a dial gauge in the middle.

It's one thing to measure what's there, quite another to change what's
there into what you might like.
