No me did not create the skf, but I do recall providing measurements to 'someone' here.

I have just returned from a week in Dayton Ohio and am beginning the task of cleaning up, squaring and despeckling a cache of photos and other materials Dr. Hans Goldschmidt gave Shopsmith from his personal collection for records preservation several decades ago.
Bob Folkerth provided me access to that cache of information that I will make available in the coming weeks and months in My Google Drive.
See link on the first page of this thread.
Today I posted a photo (in a large format PDF) of the first Shopsmith made 0001 which closely resembles the patent application, more than it does the 10E.
I took extensive photographs in the factory in Dayton and can attest personally that many of the early 10E / 10ER's used in the production of the early machines, and later the 1950's Mark 5, are still in use today.
They are providing the same machining accuracy they have for the last 60 years as they produce the Power Pro Mark 7 to the exactly same dimensions, and tolerances.

That is an understatement on ALL counts!

I started to put this in the Hans Tidbits thread, or in the First Shopsmith ever made thread but considering it has both Drawings and Photos alike, I decided this would be a better choice since it will be in the My Google Drive at some point, and certainly in the upcoming book.
There's not much in the Hans Sub-directory yet but I am working on that. From the names alone, you can see some of what's coming.
Back to this issue....
Hans Goldschmidt said in an interview with John R. Folkerth what drove him to create the 5 in one woodworking tool in the first place. The interview came as John R. Folkerth visited with Hans Goldschmidt and his wife Ilsa at their California home in 1979.
"I brought (Shopsmith) model to Bob (Chambers) for him to tell me what I should do with it. From there I bought a Drill Press and used that as the headstock. I also bought an old saw and a saw table and took a couple of knobs off my chair and built a working machine.
Although I personally found nothing in the files that I scanned from Hans’s collection in May 2018 in Dayton, to confirm it was this drill press, the photo of sn 0001 did.
I did some parallel research externally and I found out that the Drill Press he used for a prototype Headstock in the vintage of a 1930 - 1940 Craftsman. I used 1940 model 101.03622 for the parts illustration I mocked up.
I have attached a photo of two from VintageMachinery.Org of that era and cut away some of the components in an illustrated parts list of one them to allow folks to see the roots of the prototype. Hans added a wooden plate below, and crafted the two rail system that remains to this date.
Remember, his invention premise was to take 5 existing tools and combine them in such a way that one powerhead (Headstock) could drive them yielding more tools in less space for less money.
The 1940's parts list had part names for drill presses in general that remained in the Shopsmith nomenclature.
Things such as Quill, Spindle etc. were commonplace terms in the industry. - Everett

Everett, you are truly a blessing to our community.
Thank you for all you are doing. That picture of the first SS is amazing. It is very easy to see how it morphed into the first production 10E's.

Hans Goldschmidt's idea of having 5 or more tools driven from a single power source was not a new concept as can be seen from the stationary 1932 Sears Driver Power Home Workshop driven by a single motor.
This was being marketed 15 years before the 1947 Shopsmith invention. Indeed even this Driver Based Power Workshop was a scaled down version of the Waterwheel with distributed Belt and Pulley Systems in use in factories, and borrowed from those design elements.
What made Hans invention so unique was the mobility and convertibility of advanced capacity (compared to hobby or craft) power tools to another all driven by the same headstock, and the multiple ways in which adjustments could be made between tools while retaining the table tilt and miter angles between tool setups that could be stored in the space of a bicycle.
