Here are the cheeks being assembled:

The spacing of the pins for the manual was critical so I had a machinist friend of mine make a drill plate. The first hole in the drill plate is a precision slip fit over a Ø.125 pin. The rest of the holes are Ø.120. The first pin hole is drilled and then a pin is installed. The plate is set over this pin and screwed in place. The rest of the holes for that octave are then drilled:

Then the next "C" pin is installed, the plate is moved up an octave and the process is repeated:

The same procedure was used for drilling the front pins except that they are all in a straight line and not staggered like the middle pins:

Here's the front part being assembled to the main board:

Here's the box for the left side stop knobs being glued together:

Here are the left and right stop knob boxes. They are left open on the bottom to have access to adjust the stop points of the stop knobs:

Here they are being assembled to the main board:

I used a block when installing the manual key pins to make sure the pins went in straight and were all at the correct height:

This photo shows the holes being drilled for the coupler action to get to the tail end of the keys:

The holes for the stop knobs are lined with felt:

Here's the complete manual base board. The four 2x4 looking posts in the corners will support the windchest:
