[Land-speed] Piano Hinge

[Elon]

When you hang around Bonneville you see a lot of creativity. You also see
some wonderful parts and  beautiful craftsmanship. One common feature is
aerodynamic trap doors and other forms of hinged devices. Often, a piano
hinge is used. This link is a neat and simple way of laying out what would
appear to be a tedious task for hole spacing on a piano hinge.  EAA is
Experimental Aircraft Association (i.e., Home built aircraft). Warning . . .
there are other fabrication videos so plan your time in advance . . . enjoy.
