Can anyone help me with an exact ID, or better yet, factory literature on the first item shown in the series of pics at this link;
http://www.linkcycles.com/tableandbar/
It's a early 1920's Harley factory tool and I suspect that it's a cylinder lap of some sort. It has casting numbers that are very similar to the 20's frame table shown later in the series. This frame table I KNOW is a factory tool as I have the factory service bulletin that covers its use. I found them together as a pair and they both came out of an overseas dealership in New Zealand (Jones Brothers)
At the top of the unit where the connecting rod attaches to the rocker, there are three positions marked 61, 74, and single. Looks to me like changing the selection would slightly change the stroke of whatever tooling is attached to reciprocate inside of the rotating cylinder mounted below.
The unit has a power input shaft on the side. When this is turned, the table with the three posts rotates. You can see in the one picture how a cylinder is mounted inverted in that rotating carriage. At the same time, there is gearing inside that causes the con-rod in the rear to reciprocate and this seesaws the rocker on the top back and forth causing whatever tooling that's mounted to the other end to stroke up and down inside of the rotating cylinder below.
It seems that Harley would have produced some kind of paper manual on the use of such a device. They did so with the frame table so why not this?
I'd also be interested in any info on the large cast fixtures that I have for the frame table shown later on the page. I've figured out a couple of them but others are a complete mystery.
ANY help would be GREATLY appreciated.
