Howdy to all from Ron Darner. I haven't gotten caught up again since the crash, but working on it. I'm the power drill guy - collecting old (corded) drills and, especially, the "conversion tools" that make them into something other than a device to make holes. Hedge trimmers, lawn edgers, lawnmowers, and flower bulb planters; saber-, reciprocating-, circular-, chain-, and band-, hack-, and table-saws; cocktail shakers, blenders, fish scalers, and eggbeaters; putty removers, power caulking guns, and grease-pumping guns; bud trimmers ("cleans herbal material"); car lifts (yes, drill-powered whole-car lift!) and man-lifts (portable bucket lift); drain snakes; disk-, drum, orbital-, flap-, and belt-sanders; paint mixers, paint sprayers, and paint removers; lathes, routers, planers, and mortising machines; rivet spinners and pop-rivet pullers; floor buffers and shoe polishers; and on and on. I have identified more than one hundred different KINDS of such tools, so far, and many come (or came - some are obsolete, like specialized tools for re-lining drum brake shoes) in an amazing number of brands and with many different methods of operation.
I have started to document and catalog my drills and my conversion tools. Have about 150 of the drills listed so far, and 165+ of the conversion tools, but have a long way to go on both. I have also found and listed many drill and drill-related patents; I may be able to identify some where the nameplate lists only the date of issue, if anyone has questions. I have a few conversion tools which start with something other than a drill: a chain-saw-driven weed-eater, and an angle grinder-based chop saw. There are others that I know of, such as a portable circular saw made into a table saw, another into a radial-arm saw, and a reciprocating saw used to move files.
I have a number of other tools - a lot of saws of all kinds from a tiny one made for dentists to widen the space between teeth, to a two-man, 11hp chainsaw, for example, or a largish batch of parallel-jaw pliers and variants made from them.
