C8 progress in Texas

[Bob Carriere]

Your are quite the mad scientist David.

Hope you fire insurance agent is not a MLU fan !!!!!!!

What is the "stuff" used between that foil sandwich...?? some kind of fiber??

Will that fiber ignite if exposed to a flame or is it like Rockwool insulation which is basically mineral.

Now how are you going to install it to the engine cover??? Phil's idea of stiching with small gauge Mig wire using existing hole males sense. Or some kind of super glue that is heat resistant. There is a special silicon used to glue the seal around the doors of wood fired airtight stoves.

The foil covering is most effective at reflecting back infra red heat... the fiber backing is to prevent heat transfer to the other side.....

Ever wonder how a blanket or mat made of the same woven fabric as the "titanium" tape (see Jeggs catalogue) used for wrapping exhaust headers would perform. After all that exhaust tape can endure cherry red exhaust heat without deteriorating.

Great job David - that seems to indicate its pretty good at insulating.

What about a combo Bob? The exhaust material and this stuff...

[David DeWeese]

Thanks Bob and Tony,
Had time this weekend to get my engine covers repaired and painted, and the insulation installed.

I used weatherstrip adhesive to initially hold the insulation to the covers, then made new wire staples,(84 of them), to install through the original holes in the panels.

Cutting and shaping the insulation was relatively easy with a pair of industrial scissors, but it took an EXTREME amount of effort to install the staples into the material. Even a needle had difficulty piercing through it. I don't know what this stuff is made from, but...

So to help others who will be doing this, and with this brand material:

1: Dig through your plier drawer and find one the exact width of the staples you are trying to bend up. They won't look or work right otherwise.

2: Cut the ends of the wire staples at an angle to give them a sharp point. This helps GREATLY in pushing them through this material.

3: Bend the staples outward instead of into themselves when installed. Won't squash the material this way, and has a much wider holding surface.

4:Call the pentagon, as I think we have found the origin of the stuff found out on that ranch in Roswell,1947!

Thanks, David

Wow that's brilliant.....how do you "hide" UFO material from curious public.....just put it on the shelf of a DIY store

Excellent update again David. I am still hoping to find an insulation which is not that shiny silver on the outside, but as that is part of the function it will probably be very hard to find nowadays. Some of the racing guys have similar material, but that usually has the brand printed on the surface about a thousand times which doesn't help on a historic vehicle.

I loved your youtube vid by the way. Excellent work!

Beautiful job.... as usual for you.

What did you use for the wire....? Phil had used Mig solid core wire...?

Sure I can find a pair of pliers that I can either grind or weld and grind to match the original staples hole width.

I think that we are limited to using silver foil as in silver aluminium coating of some sort..... the shinnier it is the better to refect heat. Not original but may be the best we can hope for...... it will loose some of it's shine over time with surface corrosion, dirt, oil spray, etc.

And if anybody asks..... well it was squirreled away from some UFO storage facility..... if you come back at night I can show you how it glows....

Thanks for your help David.

Great job David....

How about another You tube video of you taking the new/old girl for a spin?

[David DeWeese]

Thanks Alex, I guess the shiney stuff is all you can get these days for heat protection. I did find some 4' x 8' x 3/8" sheets of asbestos behind my shop if you really want to go original. I can give you a great price on them.

Thanks Bob. I used some small diameter stainless wire to make the staples. The mig wire works good also, but was stiffer and more difficult to make sharp 90-degree bends without mashing down the type of material I used.

Thanks Tony. I took the rocker arm assemblies off the truck right after I made that video, and it's been down since. It had major wear in the rocker shafts and was very noisy. Finally got it all sorted out today, so tomorrow the engine covers go on and I can drive it again.

Thanks, David
