I have a bath tub that I want to use to melt lead in [ for a boat keel]
can a black iron pipe be welded to the drain hole? I would also like
cover the overflow hole.


Find a steel tank. I sure wouldn't want to be standing anywhere near a
cast iron tub full of molten lead when it cracks due to uneven heating.
I'd also be surprised if the porcelain didn't spall off like popcorn.
I've seen several keel pouring setups in boatyards here in Maine and all
used steel vessels. The largest was heated with 3 or 4 domestic oil
burners aimed into an enclosure under the tank.

I'm surprised no one mention Glenn's project. Go to this page and take a
look at how its done.
