I bought a cheap cordless drill only to discover after a few years that its battery pack was no longer available (and even if it was, it would probably cost more than the original drill). Instead of throwing it away, I converted the drill to spend the rest of its working life in my travel toolbox for use on holidays in the bundu.
Here’s what to do: first, make sure the drill uses 12 volts. Next, open it up and connect fairly thick leads to the battery connectors (be sure to get them the right way round; use red for the positive lead), making a small hole in the drill housing to admit them. Attach battery clamps to the other ends, and you’re ready to go. -STEFAN SCHOEMAN, TYGER VALLEY
