OK. Here goes. I pulled the gears this morning. I found it worked great to stand the assembly on the yolk on the rear drum. That made it easy to work with.
I wrapped the spider gears with several layers of heavy duty aluminum foil. I tucked in the edges in with a screwdriver to make sure there weren't places that the lead could leak through.
I picked up lead from a tire shop. I got a skillet from Salvation Army. I found that many of the weights from the tire shop weren't lead. I ended up hauling my gas grill into the garage and using the burner on the side. It worked well. It took a bit to get hot enough to melt the lead.
I found that the lead was cooling around the edges of the skillet so I transferred to a tin can. As the lead poured out, the dross stayed behind in the skillet. After that discovery, I made one more transfer to another can before the final pour. It was very clean lead by then.
I rotated the assembly until the foil was on the bottom.
I finally got up the nerve and grabbed a couple pair of pliers.
After a few minutes to cool, I rotated the assembly again and pealed the aluminum foil. You can see how it seeped through to the bottom side.
We checked for remnants of aluminum foil, then poured the other side.

I panicked a little bit when I saw that some seeped into the splines where the axle shaft goes.

A little work with a screwdriver and it came right out!

I'm in the middle of the reassembly now. I hate drum brakes. I'll let you know how it works out.
