Well been thinking about sugaring alot lately! We just got permission for another 500 taps and now its time to come up with something to drill all those holes. In the past we used a 14 volt Makita and just kept recharging the batteries. It worked ok for 325 taps but time to take it up a notch. Looking around the shop I noticed we had several 12V cordless drills with bad batteries and a few car batteries. There has got to be a way to just connect the drill to a car battery and pack the battery through the woods. Did a web search and of course there are other people who have implemented this idea already. Here is the link:

So what we plan on doing is hook the drill to the small car battery via a cord and some clips and mount the battery on a old child backpack. Will let you know how it goes.
