| Started the finish-up of the O2 installation, I needed to mount the distribution manifold. The logical place for it was in the |
|
| overhead console. After making the Alum replacement for the Fiberglass close-out panel, determined that there would be |
|
| enough clearance so I found the best place to position it so that the gague and the control would be accessable from the front |
|
| seats and the 'tube's aft of the pilot and co-pilot. So I marked the location and then proceeded to try and measure the manifold |
|
| for the 6 holes that I'd need to make for the manifold pieces to project through the close-out. I used a hole punch to make the |
|
| holes for the control knob and the gauge, and a step drill for the others. I messed up and cut a 1 1/2" hole for the gauge, but it |
|
| turns out that the gague is removable from the manifold (the control is NOT) and I could have gotten by with a 7/16" hole. So I |
|
| made a backing piece w a 7/16" hole in it and attached it with #6 nutplates to the close-out. Turns out that this will actually help |
|
| to provide an air seal. (The manifold needs to be mounted air tight as the overhead console is pressurized for the air vents.). |
|
| Final drilled the mounting holes to #27 and then debirred and dimpled them, Hand countersunk the overhead to receive the |
|
| dimples and then temporarily attached everything. I'll cover the close-out manifold assembly with some leather that I got that |
|
| matches the darker clolor in the seat and the instrument panel's. |
