OZITIM Posted July 23, 2015 Share Posted July 23, 2015 I found this meter long shifter in a guys shed in Australia. It is made my the Owatonnatool Co. Made in USA OA36 Pat Pend. I did some research online and saw that the US army purchased a huge amount of tools from OTC during the war. I have never seen a shifter like it, or as big as it. When I saw it in this guys shed, I offered him some cash and had to take it. Has anyone got any idea what it might have been used for, other than as a ships anchor.

OZITIM Posted July 23, 2015 Author Share Posted July 23, 2015 You can see my other purchases from this guy, but have a look at the german made double ended shifting spanner. That is another curious oddity. Has anyone ever seen one of those I found this meter long shifter in a guys shed in Australia. It is made my the Owatonnatool Co. Made in USA OA36 Pat Pend.

Gordon_M Posted July 23, 2015 Share Posted July 23, 2015 Well Tim, how much spare time do you have ? :angel: The first place to look is the tool forum on G503, many hits for Owatonna; http://g503.com/forums/viewtopic.php?f=48&t=242969&p=1421598&hilit=Owatonna#p1421598 .... if you get bored after a couple of months, try Alloy Artefacts for even more in depth stuff on tools; http://home.comcast.net/~alloy-artifacts/ ... but be warned, once you start to get into the difference between type 1 and type 2 pipe wrenches, or which stamping should be on the handle of a 3" screwdriver in an MB toolkit from alternate Tuesdays in March 1943, life will never be the same.

OZITIM Posted July 23, 2015 Author Share Posted July 23, 2015 This is just the sort of stuff that I need to fuel my addictive and obsessive personality. hahahah. But thanks for that, I will have a look. Very interesting Quote Link to comment Share on other sites More sharing options...
OZITIM Posted July 23, 2015 Author Share Posted July 23, 2015 OK, I think I can pretty much established that this is a war time manufactured tool, but what the hell was such a large shifter used for? Quote Link to comment Share on other sites More sharing options...
Gordon_M Posted July 23, 2015 Share Posted July 23, 2015 To me the obvious point is how small the adjusting bolt is. I'm assuming the drilling is such that only a single bolt will go it to set the size? Something large but not a huge torque, track adjuster, marine, or the like?

N.O.S. Posted July 23, 2015 Share Posted July 23, 2015 Looks like the bolt holes match in a vernier scale sense - the stock and jaw are drilled at slightly different spacing, so that for any position of the jaw there is a hole pair which correspond. So you simply close the jaw around the hex component and select the hole which allows the bolt through. Quote Link to comment Share on other sites More sharing options...
Starfire Posted July 28, 2015 Share Posted July 28, 2015 To me the obvious point is how small the adjusting bolt is. I'm assuming the drilling is such that only a single bolt will go it to set the size? Something large but not a huge torque, track adjuster, marine, or the like? The bolt just holds the jaw in place. All of the torque is applied to the two shoulders on the wrench at each side of the jaw. It does appear to use a vernier adjustment.
