We used one of those back in the mid 1980's when I was working as a caretaker at our college field station working the sugar maple grove there. Sure made tapping trees easier.
Starting in early '50's McCulloch had auger attachments for a couple of their different sized gear-drive models.Boring either earth or wood depending on what bits you used.Holes up to 8"-12" for fence posts,footings etc.The gear drive models were sold until the early-mid '70's. http://macbobaust.com/mcattachments.html
I see that type used for tapping trees. Stihl also made a drill attachment, that I wouldn't mind having. Like this one here... http://www.ebay.com/itm/STIHL-CHAINSAW-DRILL-ATTACHMENT-325-PITCH-1-2-DRIVE-/371016904040 I would think this setup would be real ticket.
The Stihl 08 power head was used to power many different tools. Here are a couple of links to one set up with a drill. http://www.chainsawcollectors.se/phpbb3/viewtopic.php?f=10&t=16580 http://www.chainsawcollectors.se/phpbb3/viewtopic.php?f=10&t=8341
Y'all do realize they make actual gas powered drills and such right? Stihl BT45 is one. It's actually a pretty nice unit if you have a need for something like that.
Yup, I'm just a bit nostalgic. I have a generator, 2,000 watt power inverter, & cordless drills to meat my needs.
