Out of frustration with trying to seal a cork carburetor
float, I machined a die to hydroform two halves of a float
from .005" thick brass shim stock.
I found that I needed to limit the travel of the brass whithin
the die cavity between drawing and annealing of the blank;
shown to each side are inserts made from 5 minute epoxy which
fit whithin the steel die cavity.
The upper half of the float has a threaded brass lug (4-40 tap
with a blind hole) for attachment to the float arm.
I tried out the float in dad's model 10 Buick- so far no
leaks!...
Thanks,
Joe
