I believe I have a leak in the lead bend of my toilet. Fortunately,
its not leaking where it goes into the cast iron waste pipe stack, but
I think it has a small hole or cracked somwhere past the toilet
flange. I have to remove more of the ceiling in the basement to see.
Are there any ways to seal a lead bend leak? Epoxy or J-weld?

Sometimes you can poke a hole in lead with a toilet auger. Sometimes
lead cracks. You'll have to get an eyeball on where it's leaking. If
it's a small hole I would sand it and goop some silicone rubber on it.
Lead is easy to solder. If it wasn't, there would be no stained glass
windows. Best to use a 60/40 alloy to take advantage of the lower
solder melting point. Clean area well and use a brush on flux. Buy
some sheet lead at a plumbing supply house, or whatever is handy, and
practice on that until you feel comfortable with your skills.
Epoxy works well. The best solution is to cut it out and replace
with PVC, but if the pipe is in good condition, I would leave it
and repair it. A piece of nylon mesh makes excellent
reinforcement of epoxy and would allow going all the way around
