Instrument Panel -
Fabrication |
 |
This will get bonded in. Then aluminum panels will be used to to mount the instruments. (This was
not used, unfortunately. The windshield should be in first ) |
 |
The panel was roughed in with some insulation foam. (Celotex) panel. The
last one was a
little too small. |
 |
This
is the basic layout of my panel.
Need
to determine, how I will get it to look that way. Aluminum, glass,
and or a combination of the two.
|
 |
Made up a pattern (using CAD software, then
cut/plotted on removable vinyl - It could be done with paper and 3M spray
adhesive) put it on foam (Celotex) trimmed it and verified the final
dimensions. |
 |
Here is the shape of the console. |
 |
Then took if off the foam and stuck it on a nice
clean melamine board. Cut some Celotex into 2"
strips and peeled one side off, this gave it a nice smooth bending ability
(like fold-a-plane), then took hot glue and glued the edge to form around
the pattern. |
 |
The hot glue sticks very well to
the Celotex foam, better than the Last-a-foam or urethane. Then lined the
inside bare foam with 2" clear packing tape. Micro'd the edges where the
foam met the pattern. Laid in 4" strips of 4 Carbon BID (some areas more)
in the edges and up the sides. Also put in 4 vertical braces. |
 |
1/4" phenolic was placed in the
top and bottom corners of the panel to support the screws that will be
countersunk and go into corresponding phenolic/nut plates that are
permanently bonded in the sides of the fuselage. |
 |
Start to finish in just a few
hours. BTW it would have been faster had I realized it was a mirror
image when I put the vertical braces in, they were removed and relocated.
(It was going too smooth!). The frame will be supported from the
underside and forward as well as the sides. Still needs some trimming but
the general shape is there, is light and strong. |
 |
Used plastic and packing tape,
and duct tape where appropriate. |
 |
Made up some "precision" foam blocks and fit them in the panel.
These will hopefully hold the stacks of radios. Had to cut the back
side down to make adequate clearance from the windshield. |
 |
Then glassed with Carbon fiber
and BID cloth. |
 |
Once again working with Celotex foam, I peeled the black side off, it
allowed some compound curve without splitting. |
 |
You can see the little hump
where the center stack it located. Next is to lay in a panel over top of
the form. |
 |
Ended up using the Celotex for a pattern for 1/4" foam. Glassed the
top, let cure, then beveled the edges for the bottom glass. Notice
the sanded areas for the defrost vents. |
 |
Bottom glassed and wrapped to
topside of panel. 4 BID flange for screws that go into the panel
frame that has corresponding nut plates installed. The top and sides
of the panel are very rigid. Just need to support the bottom. |
 |
Close-up for a general idea of the
layout. Had to move the FM tuner/CD player up for the deeper
instruments below. |
 |
Trimmed the panel and boxes to
fit, and the trays fit nicely into the boxes. |
 |
Instruments and radios mounted.
The Heater - defrost controls are fitted in to place. The BMA/EFIS
Lite should be in next month. Wiring continues. |
