Subject: Re: Making 'V' Weights

I use the preheat flames from my cutting torch to provide heat.  The heat is
applied from the top and since the torch is pretty hot, the melting happens
very quickly.

A small steel bucket with a foot of heavy steel wire to extend the handle is
my crucible.  A small prybar lets me pull the bottom edge of the bucket so I
can pour.

I work outdoors with the wind at my back, wear goggles, solid shoes and
welding gloves, and have a pressurized garden hose nearby.  With the speed
of the cutting torch and the wind at my back, lead fumes aren't a problem.
I have everything very close to the ground so when I stand up I am well away
from any nasty gasses, vapors, or fumes.  The cat and dog are locked in the
house and the neighborhood kids aren't allowed in my fenced-in back yard
during this.  Everything is dried off so I get no steam surprises.

At one point I wore full welding leathers for casting lead.  I since have
gone to just heavy work clothes and a welding shirt.  If I didn't already
have the welding clothes, I don't think I would buy any just for this.  Just
make sure there are no ways for molten lead to fall inside your clothes or
shoes.

Try loading up everything with cold lead so you will find out if anything
can't handle the weight.
It _really_ sucks to find this out with molten lead.

Once the lead is in the mold and solidified, I use a light spray of water to
speed the cooling.  Don't get carried away with this.

I want to make a 'V' weight in preparation for my new twinset, which I'm
ordering soon. I have the lead weights, and I can make a mould no problem,
but I want to know how best to (safely) melt the lead down. Any ideas about
heat source and suitable container for molten lead? Protective gear?
