Combo update for Fri & Sat. Sanded all of the flox/micro build-up on the back of the plenum flush. Still had some areas behind |
|
#6 that required more filling, so more micro and then more sanding. All of the spots that can/should be filled are filled and |
|
sanded (except across the front of the plenum.) There are several pinholes etc. that I'll wait and fill when I do the paint prep for |
|
the plenum. Built out the cup that filts around the upper right motor mount so that it was flush with the baffle. It still may require |
|
some additional build up (3/16"). Made some reniforcing plates for the aft baffles and then match drilled them to the upper rear of |
|
the plenum, and attached #8 nutplates to the plenum. This gets that back seal closed. The remaining challenge is to close the |
|
front seal around the engine case. talked to Gary Foster about how /what he did, and concluded that he probably has the best |
|
idea, and that was to cut off the contours that came with the original plenum, and apply some release agent/tape to the engine |
|
case and layup a custom 'seal' with the plenum secured in place. The original is close in some places but has over 1" gap in |
|
others. Went to get more Hi Temp epoxy but they were closed Sat. !$#6%$%. since I need to mount the control cables and that |
|
requires some instrument panel prework, I've been using heat and some clamps to get the Aerotronics instrument panel to |
|
better match the contour of the glare shield. I began to fit the CNC cut panels I got from Aerotronics. I remade the left panel as |
|
I'm not going to mount the SIR compass in it as it's canted at an angle and will give a false reading. |
