Thanks!

We are making progress, and as is the case, there are many skills and processes that will make the Airstream better once the Alfa is gone!

Here is one...
We needed to fabricate an exhaust heat shield for the Magnaflow SS exhaust system that runs hot and close to the drivers floor.
We rolled a piece of aluminum, folded the edges, and then I began looking for some heat insulation material.
My buddy then says... let me help you with that, as he is in that business... and here is what I ended up with!


He tells me its a fire retardant fiberglass/mica material and is good to 2000deg or so... I will get the full spec soon..
He said to protect it from oil absorption by adding a layer of foil on the engine side.

Anyway, I am thinking that this would be PERFECT to line the inside of the doghouse with!
The roll is 4' x 15', and I only used a 8" wide strip off one end!

And of course, the heat shield became a little test bed....




Aluminum must be polished and riveted!


Backside..


Test Mounted...


Interior is almost finished... Another step forward toward getting back to the Motorhome!

Yes it would Derek... But we need more space for our Dogs!


I got the info on the heat shield stuff... I think it will work well!


ZetexPlus® is woven from highly texturized continuous filament yarn and treated with a proprietary vermiculite-based coating. The coating allows heat to disperse evenly across the surface of the fabric, significantly boosting temperature rating and abrasion resistance. Newtex’s proprietary vermiculite coating has larger platelets and a greater percentage of solids than competitive coatings allowing for better coverage and superior heat dispersion. Our coating also features an organic adhesion promoter to improve the bond between the platelets and the fabric. The adhesion promoter reduces flaking and wear for a longer product life. It also improves the fabric’s resistance to moisture.
ZetexPlus® can withstand constant operating temperatures up to 1500°F (815°C) and peak temperatures up to 2000°F (1095°C).
ZetexPlus® is commonly used to fabricate protective gloves and mittens, blankets, covers, heat shields, insulation, and jacketing.

Its been a while since I have been here.
Various health and other issue have kept me away from Airstream work, but it coming.
The Alfa work is almost done, and soon it will need little of my time, and energy.

As I said before, there are many parallels with the Airstream work ahead and its a nice test piece.
Excuse me if I share some of the things that have been done.

The Alfa's fuel tank was a mess inside...
Today's fuels attract and hold moisture, which leads to rust and varnish..
This is the result...




After cleaning and derusting LOTS, it was looking better, but it looked like there was some other kind of liner, so it needed more work.




The final fix was a tank liner from Red Kote.


It was poured in thru the various pipes to ensure complete coverage.



The excess is allowed to drain out, and the coating was left to dry for a week, after which I added a 2nd coat.


After that, the outside was refurbished to complete the job.


Next it was a TIG welded hard-top stand, that was painted to match the car.


And to finish the interior work, the trunk was paneled and carpeted.


Maybe 2 weeks more work, and then it back to Airstream stuff!

Now things are easing on the other project AND I am feeling a little better, I promised myself I would start doing some small things on the AS.

I have re-written my priority list... and this little job was on it.

Had a nice set of Mickey Thompson cast aluminum valve covers, and planned to powdercoat them, however, there was a problem with them.
Someone in the past hogged(more like chewed!) out the breather hole and they were too big for my PCV valve, or anything else. So they needed filling in before I redrill them to the correct size.

The aluminum filler needed to be thicker than any sheet I had... so upon looking about my shop, I found a damaged Honda Oil pan that was in my scrap pile.
Cut it up to get the flat section I wanted.


Which I cut and filed to fit the hole...




I had never TIG welded on cast aluminum before, but after fiddling with the setting a bit, I managed a reasonable job of it!



Grinding, and making it flat revealed a little porosity, but its solid and good penetration, which will be ok, as it will be hidden by the PCV valve grommet. Hopefully, with my settings correct the next one will come out better...

Hopefully, when #2 is done, I can finish prepping for powder!

Bring it on!

Today's progress...

Prepped and ready.


Gloss black powder on...


Into the oven it went.... only just fits, that why it is suspended like this... the back edge hits the back wall, but only where its not coated!


Flowed out at 450F.


After 20 mins at 400F, it was left to cool... a couple of porous spots despite preheating to 500F, but they will be hidden.


Some detail work, and its almost finished... onto #2.
