This part was made for the Tri-State Warbird Museum.  They had an original that had one of the "ears" broken off.  I was given permission to use it as a sample to make the pattern and core boxes from.  They also loaned me an intact and servicable original that doesn't belong to them to use as a sample.

The broken original was cut in half along the original parting line.  All holes were filled and the cut surfaces were built up with sheet wax to allow for the metal removed by the .062 in. thick slitter saw.  The internal areas were used to make "male" casts which were in turn used to make the cavities in the core boxes.

The intact original sample part is on the left and the BCA part is on the right in the last two photos.

P40 Aileron Trim Motor Mount Plate

This is the motor mounting plate for the P40 electric aileron trim tab.  The original is zinc die-cast and was broken in two as well as having several pieces broken off. They can be seen laying next to the original on the right.  The new part is machined from a solid piece of 6061T6 aluminum and fits the motor, gears, and sundry other parts perfectly.  I'm informed that once power was applied the assembly works.

The left hand photos shows the top of the motor mount plate. The right hand photo above shows the bottom side of the motor mount plate.  Original assembly was made by the W.C. Gilbert Company who went on to manufacture the post war Erector Set and various model train sets.  This particular part was made for the Tri-State Warbird Museum in Batavia, Ohio.

Rear Mount, Outboard Wing Gun Curtiss PN 87-69-703 (P40)

This is our outboard rear gun mount casting.  The original extrusion is seen on the right. It was heavily damaged by intergranular corrosion.  The mounting holes in the new casting will be match-drilled  with the exisiting holes in the wing by the customer.
