Commander #155 'Mephisto Cat'

That aluminum mast base is absolutely gorgeous! Lucky Boat!
You came out the egg, as you say, an engineer - how you created such a controlled and sharp-edge curve on the bottom is masterful.
Actually unbelievable.

We have a Grizzly vertical milling machine now in the shop here and Mike has just set it up with a digital controller. I mean I can visualize machining process now that I see how it's done in person and do menial tasks on the thing - but he too would be impressed with the difficulty of producing that curve on the bottom of the mast step.

Since my egg was cube shaped, my method would probably be something like a half-round metal file mounted on a swing arm activated by a bicycle pedal crank and chain and a sort of tilting table that the operator by eye would move into the swing file. The machine would be marketed under the Chimp logo.

Altogether the piece is brilliant
