http://www.bobvila.com/forums/Tools/posts/42900-craftsman-model-665-256560 I have one of these in my hot little hand, but can't identify it. It appears to be a speed increaser/reducer, don't know which. One end has a threaded hole whic h might screw onto a small drill press arbor, and the other end has a 1/4" squar e drive exactly like a ratchet. I am thinking torque increaser, but it is more c omplicated than others I have seen in the past. Any help out there?

It's a reversible screwdriver speed reducer. I'd tell you where to find a pic of the tool sitting next to the original instruction sheet, but I'm sure if I did then a gang of purists would come to my house and cut off my fingers - or at least remove all the vowels from my keyboard. If you really can't live without seeing it, then ask me again in 1 day 13 hours. Joe M.

Come on Joe, not that hard to find an expired listing http://cgi.ebay.com.sg/Craftsman-Reversible-Screw-Driver-Parts-List-1957-/370513 878000?pt=LH_DefaultDomain_0&hash=item5644591bf0 On Tue, Jul 12, 2011 at 8:38 AM, Joe |

Jim: A quick google gave me this: http://www.renovateyourworld.com/wwwb- oard/messages/craftsman_665_256560_speed_reducer_304275.html It's a speed reducer. The correct p/n replaces the hypen in the number, so it's actually 665.25650. The period/decimal point was replaced with the hypen in the URL due to the way browsers interpret the period.

There were a couple of answers to my query: The answer which said it screws onto a 1/4" drill shaft, and is used as a screwd river, makes sense. But the one which said it was reversible by holding one half or the other does not. By hand holding the front half of the large cylinder, th e speed of the output shaft is reduced, and the ratio is 14:1. The same thing ap plies when the direction is reversed on the input shaft. The rear half turns wit h the input shaft. It seems that this is a 1957 product, and I wasn't aware that drills were revers ible back then, but then there is a lot of stuff I don't remember anymore. I sup pose they were reversible, but my memory is not. I assume from the description I read on this tool that the 1/4" square drive tha t it has on it was an option back then. I am aware of the tapping device you mentioned, but this is not one of those.

Another one day and 3 hours and all shall be revealed - a pic of the instructions with the tool sitting right next to it. I promise. In the meantime, yes drills back then were reversible. I had one of my grandfather's "handheld" drills from the fifties. (Apparently in the fifties people had really big hands. Must have been the radiation from all those nuke tests.) It was a thing of beauty, all metal, and had a metal switch above the trigger - push to one side and it was forward, push to the other and it was reverse. Joe M.

I remember an all aluminum 1/4" Black & Decker drill that I inherited from my fa ther. That thing was a drop dead torquey tool that lasted forever. Right up to t he time somebody borrowed it, and it never found its way home. Then B&D became a second line, and DeWalt became the first line. Before that B&D was a killer too l. I still look for old all aluminum frame tools when I am out searching in the wild.

Hi Jim On 13/07/2011 9:59 AM, James Thompson wrote: > I wasn't aware that drills were reversible back then I wrote: "Pressing down would drive the tap, and raising the device would reverse the tap's direction." To elaborate: the drill press always turned in one direction, and with downward pressure, caused the tap to turn in the same direction, cutting the thread. Raising the "chuck", caused it to turn the tap in reverse - unscrewing it from the thread it had just cut. Neato device, but it required some care to operate it, and it did not need to be held by hand. PeterH in Perth ------------------------------------------------------------------------ |

Auction is over, here is the tool, with instruction sheet right next to it. I've got another photo of Bigfoot using the tool to fight off the Loch Ness Monster, but I've still got a couple shots left and didn't want to get it developed until I finish out the roll of film. http://cgi.ebay.com/VINTAGE-CRAFTSMAN-REVERSIBLE-SCREW-DRIVER-SPEED-REDUCER-/170 664895108?pt=LH_DefaultDomain_0&hash=item27bc6ba284 http://tinyurl.com/6xgruag Joe M.
