Im also cast parts now and then.
I learned to do it at a old foundry
in Finland in the 70s Before they
was to tear it down.
One of many things i regret i dont
took Pictures of during the years .
The whole floor in the foundry was
covered with about a feet of sand
so you just shoveled up some of the
floor
. to make the molds.
They had made artilery grenades and bombs
for the Germans during the war
I still have a bunch of german detonators i picked
up from the junk heap behind the foundry
I wanted to bring some empty bomb shels with me
but my dad dont thought it was a good idea
to try to take them across the border
About the emblems my sister is a Jeweler
and some times she had made emblems
in silver or gold for cars
last time i Think it was for a Thunderbird
so if you want a real nice emblem
Contact a jeweler and get a price qoute
its not that expensive and you get a real
nice finnish on them
