Center Stack Done

The drilling template used to locate the avionics tray mounting holes worked great. After clecoing into position, I used a neighbor's pneumatic angle drill (the new one I'd ordered is still in the mail) to drill the #19 holes for the #8 screws used to mount them. I test fitted the two .040 shims that fit on either side of the trays that fill existing gaps. I needed to thin one shim down to .025 to fit. Placing it flat on a workbench and running over it with a palm sander did the trick. With the shims in place I get everything bolted in using the nut plate clamping strips I'd fabricated earlier. Access to the 4 forward screw heads was very tight. Fortunately, I have a small ratchet wrench with fine teeth and a Philips head attachment. I used that to cinch down the screws in the confined space. The final test was sliding all three boxes in position and locking them in. Everything fit well and I pleased with how it came out.
