Propane bottle & gas ring
Regulator, not the 37mbar ones used for camping stoves
I use a cast iron pan, think they are called creuset or summit, £2 from car boot sale, binned the wooden handle and got a steel one made.
Good ladle, got mine from a plumbing site, I'll find a linky when I'm not full of wine.
Metal spoon to remove the crap that floats to the top.
Warm both ladle & spoon before you dunk them in a pan full of molten lead.
I used to use snips to cut the lead in to pan size pieces but it takes too long so now use a blow torch now to melt the bigger bits over the pan.
As many moulds as you can get, DCA if possible the rest are crap.
If you are making large quantities the moulds get too hot unless you have a few on the go, I melt about 20lb of lead at time so if you use one or two moulds they are too hot to handle after you've poured it.
Clamps for your moulds, draper do a pack of two quite cheap.

I built a hearth out of fire bricks so all the heat is contained.
Roll of stainless 1.2mm welding wire for loops fits most moulds, I'm too tight to buy loops
and most important, some good gloves and a full face mask.
All the usual tips, never add more lead to a hot molten pan full, especially pipe with a sealed end


in fact unless it's free never use pipe
or..... you could just ring the lad that sells 12oz leads for 37p each, doubt you can buy lead, gas, etc for that price but for me making my own gear is part of the enjoyment.
Good Luck!
