I have a question and maybe someone might be smarter than me that can explain it (ok almost everyone is smarter than me:) )
In the construction industry every "engineered component" must undergo fire rating tests and certain assemblies, I.E; floor joist with subfloor and with or without a ceiling, yada, yada, yada. All of them must withstand a minimum of 20 minutes of direct flame and over an hour of extreme heat per ASTM standards. In the wood truss market, like I am in, nearly all the info you can find states that wood will char thus insulating the underlying wood allowing it to with stand a burning building much longer than a steel structure. That is why most steel joist in office building must be sprayed with an insulator as the steel loses it's strength rapidly when exposed to flame and heat. I would think aluminum with a melting point of only 1100 degrees would fair even worse as it would take much heat for it to lose it's strength. So my question is, wouldn't wood actually be a logical choice? Granted would doesn't do well in oil or gas, but with concern to fire? Just a thought? I wonder how many actual engine mounts have failed do to fire thou also?

However, since those pictures were taken, the spacers have been replaced with aluminum spacers of 2 1/2" diameter by 2" thick. They were made from solid round aluminum rod drilled for the proper bolt size. When I put the original wood ones in I wasn't thinking of the potential danger of an engine fire and the possibility of destroying them if there was one. Since then, I've grown wiser thanks to all of the construction instruction that's available on this web site. All of those who contribute to this site are to be thanked for all of the helpful information that they provide.
