Instructions for Mansfield Do-It-Yourself Sinkers

Sourcing Lead
Most of you will have some scrap lead lying around. Try visiting your local roofer/plumber or scrap dealer. Lead is worth around a $1 or $2 per kilo. Another excellent source is to use discarded wheel weights from your local tyre shop. These weights have a hardener added to them and work superbly as sinker and jig material. Although less durable for jigs, pure lead does work very well for us, so don't be put off using it!

Melting Your Lead
The secret to making sinkers and jigs in volume is to have a large amount of lead in a molten state.  To acheive this use a Mansfield Melting Pot which is curved inside to allow a ladle to scoop lead easily. Although not as effective, a cast iron pot will do at a pinch. Use a gas ring or BBQ to melt the lead.

Ensure that you use adequate ventilation when melting lead as the fumes are toxic. A common mistake is not to melt your lead to a "bronze" colour which is substantially hotter than a liquid state. DO NOT under any circumstances allow moisture or water to get in contact with molten lead; it splatters dangerously!

Pouring the Lead into your Mould
Scrape off any impurities from your lead by simply scooping off the top layer of "rubbish" that forms once your lead has melted. Heat up your mould before pouring the molten lead into the mould. You may be using a hinged mould which can be clamped together using a D clamp.

Use a ladle to pour the molten lead into you mould. Open mould once lead has cooled suffienciently (this only takes a few seconds). Once the sinkers are completely cool, then remove them from the moulds.

Here is the equipment that is used to make sinkers. A gas ring is the best method of heating. Remember to heat the sinker moulds first before pouring the molten lead.

These sinkers are completely cool now and can be safely removed from the mould.
