I am looking for an elliptical cam locking device. This "lock" will be
permanently affixed to an interior steel panel and the elliptical
locking part will pass through an outside panel that will have a hole
that matches the lock profile. When you rotate the lock mechanism the
cam action will draw the panels together tightly and the elliptical
aspect will keep the "lock" from slipping back through the hole. This
will need to be able to hold a ton or more static load but I can gang
them together to accomplish this. Before I make one I was hoping I
could buy something similar. Any help greatly appreciated.

Thanks, Steve

Sounds like a roto-lock , sometimes called a coffin lock.
They're used to hold stage sections together. most theatrical supply
companies should carry them. Many sound/light companies also use them on
road cases, so you may be able to pick them up at your local music store.
