Why would you want a pie WARMER Titch??
I have been given a new job description,new location lots of country driving.Phillip island area.
I leave home around 5 each morning ,I thought it would be nice to have a hot breakfast. ahh that reminds me, a friend wrapped some sausages in foil and attached them to the manifold on the motor and drove along for a while before we stopped for lunch, it seemed to work.
don't 'ya wrap in foil and stick in motor somewhere... (just don't mind the fume flavour!)
Too hard for me ,a half hour job to get to the exhaust manifold.
Many years ago my F B Holden had a plate welded to the extractors for that reason,heated tinned food fantastic ,once you remembered to pierce a hole in the tin,Baked Beans make a mess in the bonnet bay
