Key Leads

[Cy Shuster]

So you pour the lead right into the hole in the key?  Do you drill all the way through?  How do you block the other side?

It's a nice refinement when swaging the leads, that if you use a punch that expands the lead in only two opposite directions, it's best to align that punch so the expansion force goes against the end grain of the hole.  If the force goes vertically (against the side of the grain), it's more likely to split the key.

  Pouring the leads has been my preferred method rather than buying pr-made weights. I use a great little device from the U.K. called a 'LEE' lead pourer. It doubles up as a sinker maker for fishing, which I also enjoy.
  The beauty of this device is that it is easy to use, and with care does not burn the wood.
