Hello,New guy stuff here. I just bought a small 4 frame extractor with free shipping From Brushy Mountain.After looking at it for 2 seconds it was obvious how easy it would be to attach a drillmotor to it. With a 3:1 increase in speed the drill will only be turning about 100 RPM.I have photos here :http://mikesfarm1.blogspot.com/2007/12/extractor-mod-completed.htmlRegardsMike
