Phenolic spacer

[Shrinkdude]

Has anyone made one and put one on their car?
I made one and so far it seems ok for the one trip around the block.
My thought on why I made one was to reduce the heat being transferred from the manifold to the carb. Mine is 1/4" thick made from phenolic sheet I bought from Grainger.

wouldn't it be better if it were maybe five inches square?just asking....

I made it to fit the RBS carb I have on the engine, I used the bottom as a template.

8) pretty good design there. you can help disapate even more heat if you also make a 1/4" thick spacer from wood and sandwich it between the carb and the phenolic spacer. and yes it really does work.

Why not just a 1/2" phenolic or marine plywood spacer?

I guess it would be rather expensive to buy a whole sheet of 1/2" plywood just to use a couple square inches of it.

I am getting close to bottom of the hood with the air cleaner and larger wingnut I have.
Maybe I will try 2 pieces of phenolic to get 1/2" down the road sometime

He's saying that you should use two dissimilar materials so they have a different coefficient of heat transfer. Two spacers of the same size is just one taller spacer. So try 1/8" material like marine plywood or Masonite.

Shouldn't a thicker spacer with the best insulating property be better?

 

[ludwig]

Of course. But he already has one at 1/4". He is concerned about clearance if he goes 1/2" so, what the hey, split the difference. The best would be a solid phenolic or marine plywood spacer. All I'm saying is that I'll bet he can put his hand on some hi-po laminate or something similar for just a little more bump.

Haha, I was wondering if there were some special secrets involved in homemade spacer-making

 

[ludwig]

some special secrets involved

mmets

Pssst: *whispers* more meat = thicker spacer

 

[Shrinkdude]

The secret is to get the middle hole right and then worry about the 2 outer mounting holes. 8)

Just jam a corn cob down the big hole to keep it centered and then rattle a fat drill bit around in the mounting holes until you can pound it down over the bolts.

Great minds and all that.
