FWIW:

My Goldie SN 377425 produced by Magna American is a poly-v drive with 1 hp dual voltage motor. At the time it was produced(1963) a 1 1/8 hp 115v motor was standard.

AIUI the two screw belt cover originated with the "B" headstock. There were belt covers that had 8 screws.

Also the "B" headstock introduced tinnerman nuts replacing tapped holes in the belt cover as well as the 5 motor pan retaining screws.

Another change in the 510 tables was the early rails that mounted with torx screws into tapped holes in the table front and rear edges that were accessible through holes in the front of the rails. The id of the rails was slightly smaller then. I think 86 is accurate.

The two Greenies I have restored were both early "B" headstocks and have 6 screws for the belt cover. "A" headstocks without the rear access hole and high speed lock ended in October 1955. JPG which belt covers had 8 screws. The "B" headstock and it's internal parts have had the most changes over the years.

That must be the change in 1986 that makes the difference between which 510 to 520 upgrade is needed. I wondered why the early 510 fence tubes had holes in the front side of them since I have not had a 510 before. Thanks, JPG

The "A" greenie headstock casting, belt cover and motor pan were e-bay purchases and I know nothing re their history(no vent plate/SN). The casting has the rectangular speed control hole and no access hole.
The 8 belt cover screws are one top, one bottom(motor pan), the usual two near the 'bump' two more at the casting motor pan juncture(very close to the typical motor pan screws) and 2 more low on the motor pan(the extra 2).

It is destined to be a Power Pro headstock(sigh some day!!!).

Just 're'discovered this regarding the 'second slot'.

It defines the time period they were made. 53 - 80

JPG,
Thanks for making the notice available. I understand why you thought they always had the extra table slot. Almost all of the "Greenies" I have seen or seen pictures of did not have the extra slot, but some, in pictures, I could not tell for sure. Maybe another case of Shopsmith Inc. not knowing the Mark 5 history since the notice is dated 1/80 and calling them Mark V which is the same time period the name changed on the machines Serial Number/vent plate from Mark 5 to Mark V.

AS for the 8 screw holes

The 8 belt cover screws are one top, one bottom(motor pan), the usual two near the 'bump' two more at the casting motor pan juncture(very close to the typical motor pan screws) and 2 more low on the motor pan(the extra 2).

Below is a picture of one of the two "Geenie's" headstock that I restored. Note the screw hole locations circled in red. Sorry the lower one does not have the screw in it yet and of course we can't see the bottom one.

I have to assume someone decided they were unnecessary.

They all appear to be 'original'.

Again history/vintage unknown.

It does all look original. Maybe one of the first Mark 5's produced.

I located a news clip through the Mississippi Department of Archives and History where WLBT Newsfilm collection captures the Raymond, Miss. Dedication ceremony for Magna-American Corp. November 15, 1966.

This timeline helps define the transition of the plant to Raymond, Mississippi by Magna American which was the beginning of the end of manufacturing for that era of Shopsmith. I have more on this time line, but will defer that to the upcoming book.

Copies of the media can be ordered from them should anyone have an interest. I did not pursue it.

I believe that's where John Folkerth went to in 1971 to find the casting dies.

I believe that is where he went to obtain rights to make and sell sawsmith blades and 'found it all'!
