I've just registered in the new location.
By way of introduction, I have a collection of drills and drill conversion tools (things which change them from hole-boring function to . . . well, you name it! Hedge trimmers, bulb planters, fish scalers, power planes, circular-, sabre-, reciprocating-, band-, or chain-saws, wood lathes, and on and on). I've begun cataloging my stuff, and have about 130 drills and 160 conversion tools or accessories documented so far. Many more to go.
I spent the past weekend at a swap meet/auto show at Jefferson, WI (local), and bought another batch of old drills. Haven't made final count, but think it was about 15 of them. Also just received another power drill belt buckle, this time a Black & Decker that a friend found on E-Bay. Good choice: I have at least 25 B&D's in the collection.
I've gathered quite a bit of information on patents, too; if you've got drills or related devices, tell me, and I may be able to provide additional information on them. And I appreciate any info that you can furnish on drills or attachments that I don't have - thanks in advance!
