Melting the lead / fitting the bulb shape

[cuorefocoso]

Hi
What kind of expierence you guys have in melting the lead? I am trying to make a part of a bulb, approx 100kg. I see it will be not so easy to handle it as a single solid piece in preduction process. But what is divide it in parts - will it join to a even (solid) piece if three separate melts will be poured into a mould? I mean should they stick to each other?
And afterwards, will the epoxy filler stick to lead to have a smooth and nice finish?
All coments are welcome, these about home-made methods specially.
