You beat me to it Mel.

Wrap the old one in some aluminum foil around the sides and bottom to make a mold and set this in some dry sand to hold it in shape. Now place the old one in a tin can on your camp stove until melted and pour away. Make sure you use the appropriate safety equipment when doing this.

All early RV's were poured by the builder directly into the elevator horns to form the balance weight. I used lead from old wheel balance weights.

Default Broken drill bit.

Old topic I know.. But I just did the same thing, broke a drill bit deep inside a lead part.

Turns out it was an easy fix - I exposed part of the broken drill bit by digging around the 'stump' using a small flat blade screwdriver, then I heated the broken part up using a small but sharp butane flame. The drill bit heated up and slid out of the lead using a pair of tweezers. It was then it was as easy as feeding a stick of lead through the butane flame into the pre-heated damaged hole, a quick file, and re-drilled as normal.

Hopefully this could be useful to someone else in the future - I never realised how grabby lead can be on a drill bit!!

Default Use silicon lube

Use a silicon based lube when drilling lead and go slow, don't let the heat build up. I use triflow it works the best for me.
