219039 James Thompson <oldmillrat@m...> Jul-12-2011 Mystery tool (a different animal this time)
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
which might screw onto a small drill press arbor, and the other end has a 1/4"
square drive exactly like a ratchet. I am thinking torque increaser, but it is
more complicated 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.

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. Charlie Rodgers

When I was turning Sputnik - yeah - Sputnik components out of brass to 
make up sprinklers ;^) I had to use a device similar looking, in a drill 
press to cut threads in holes. Pressing down would drive the tap, and 
raising the device would reverse the tap's direction.

Does you unit exhibit this type of action Jim?

219067 James Thompson <oldmillrat@m...> Jul-12-2011 Re: Mystery tool (a different animal this time)
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
screwdriver, 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, the speed of the output shaft is reduced, and the ratio is 14:1. The
same thing applies when the direction is reversed on the input shaft. The rear
half turns with the input shaft.

It seems that this is a 1957 product, and I wasn't aware that drills were
reversible back then, but then there is a lot of stuff I don't remember anymore.
I suppose they were reversible, but my memory is not.

I assume from the description I read on this tool that the 1/4" square drive
that 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.

I remember an all aluminum 1/4" Black & Decker drill that I inherited from my
father. That thing was a drop dead torquey tool that lasted forever. Right up to
the 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
tool. I still look for old all aluminum frame tools when I am out searching in
the wild.

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.

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.
