Polishing actually Dulls it....? ( Nickle tone ? )
But it blends it better .
I went over the whole cover...
Then concentrated on killing/polishing the swirls that were by hand...
Maybe I should have used a scuff material instead of sand paper.
I'm still debating whether to paint it flat black.
The design would still be seen through the paint.
( and could be removed with lacquer thinner )
....Hmmmm, second thought...The black might bring back Fab Scars.
I think it needs the Dazzle to camouflage this piece...
or a layer of Carbon Fiber...I saw One yd...6o inches wide...$48 bucks
I think my West System Epoxy would work with it ?
.
That sounds like later or never....
.
I'm working on the chaffing material and wool seal now.
I need more of the Blue chaffing material ( Jo Anne Fabric )
.
Then I can finally move on to other things needed to START the engine.
I think I'll be getting the RPM cable next.
Oil pressure gauge, fittings and tubing should be local auto store.

Hey Guys ,
It has a good seal ... The wool does a good job of filling uneven gaps .( as it breathes , it will clog and seal better )
I bought 10 ft of the Blue chaffing material for $12 bucks at Jo-ann fabric .
( Aircraft chaffing stuff ...$36 bucks and higher , and it only comes in white ...)
.
The stuff is a woven cotton ...flat ribbon ...bumpy.
To make the holes in it , I use a nail heated with a propane torch .
After I made the hole in the cotton weave , I dabbed it with some polytak...
This should slow down Fraying...

Hey Guys ,
Here's the cover after the chaffing / Seal has been glued .
I'll leave it like this for drying .

All of the Dzus fasteners have good locking tension .
(That's something I will need to check after heating and cooling )

I still have to route the oil breather ...
and spark plug wires / guides
.
Some of the pictures are the same angle as previous pics.
Compared to them , ..... what scars ?
.
Polishing the swirls in this area will also help in wiping OFF the grime ...

Hey Guys ,
My plan was to fasten the spark plug wires to the flange ..
But in the process of trying to shield the wires from rubbing , I think they are ok.

I don't know how well this plastic will hold up to the heat ...another thing to watch .
I was thinking wool would be good as a wrap ...weave.
Hmmm...

Yeah , I looked up this part too many times...
My fault it was long ...
.
At the bottom it sez measure the cable from tip to tip...
But that is for ordering the cable only ....not the assy.

Hey Guys ,

Yeah the cable is a pinch long ...That's not why I moved the instruments .
.
The Tach cable was fighting the cross tube ...
I didn't like the quick bend ,
Moving the gauge to the other side...instead of tilting ...I will still slip a nylon washer for slight tilt .
.
The nylon hardware will be dyed or sprayed black .
The top picture , the cable disappears under the encoder (wrapped with wool).
.
The instruments didn't just move to the other side easy ....Two did.
The other two needed more taken off , lower left corner on both...
So to go BACK ...there's just more space .
.
I could have moved only the RPM Gauge ...
This is easier from a maintenance point of view ...

Hanging the Oil cooler in place told me the strongest way to mount it ...
As I put it where it was out of the way , it got closer to the firewall .
Two Brackets off the firewall would be strong ,light and simple
I would control the incoming air at the SCAT ...some round butterfly flap.

But as I was thinking of SCAT from the Plenum...I might move the cooler ,
(I'd rather not put a hole in the Plenum)
Then use SCAT coming from the air scoop on the lower cowl.
I need to have an area with a cooling draft/flow , and make sure that the oil will drain ...
Lower and more centered looks good , It might need a heat shield to deflect the hot exhaust pipes .
I'll need to hang the oil cooler in place like I did here .
Another thing I need to watch is how the oil lines will run to the cooler from the engine .

So I had an idea of the angle ...

So I drew a paper mounting bracket ...
hmmm, changed the angle and drew it again ...

Finally I started making more room .
and cleaning up the spark plug wires helps .
.
plus I have been looking at hangers like the fuel tank straps .
for center support for the tank , but mostly for a solid mount for my center controls ,
and it will protect the center fuel line and fittings from clumsy feet
.
If I have to remove the tank ...there will be plenty of reasons

PS...Still on firewood duty too
