Today I had another tinkering session.
Today's subject was melting lead. I had previously bought a few kilos of lead from our local scrap metal merchant.
The first try was putting a few pieces in an empty bean tin, and apply heat from the top using a hot air gun. The lead melted very quickly, but when I began to pour the molten lead, it started to set as soon as it touched the mould.
Second attempt was in an old copper bottomed pan on my wood gas stove. The lead eventually melted, but as I stirred it, the pot stand collapsed throwing the hot liquid onto the patio. Luckily once set, it came up in a large flat solid mass.
Final attempt. Fire up the chiminea. Once I had a nice hot fire blazing, I put the pan inside the mouth of the chiminea straight onto the fire. Within minutes, I had a metallic soup.
I then heated the mould with the hot air gun, and poured the lead with a ladle.
The lead balls came out perfect every time, the waste melted down again in seconds. I made 80 balls today using a fraction of the lead I'd bought.
Once I'd finished, and the fire had gone down, on went some water in my German army mess tin for a lovely brew.
I reckon with a few modifications, the chiminea will come in useful for knife making, and general blacksmithing attempts.
