TexasTransplant,
I am sorry to hear that the Rustoleum oatmeal color has been discontinued. I did that Goldie restoration over 4 years ago. Rustoleum has a gold Hammered Finish paint but I don't know or remember how it compares to the original Shopsmith Gold color. I'm not sure if I tried the gold color when testing colors.
EDIT: I have compared the Rustoleum Gold Hammered Finish paint to the Mark 5 Goldie's original color and it is not even close to a match. Not having a suitable color paint has kept me from doing another Mark 5 Goldie restoration.
David and JPG,
I don't recall any problem with the length of either the bench or way tubes not seating completely into the base and arms of the double tilt upgrade when I added it to my 2001 Mark V 520 a few years ago. Both of the bench tubes are seated against the stops on each end in the bases. I don't want to take apart the way tubes and arm parts but I believe they are fully seated too, IIRC.
The bench and way tubes of the Mark 7 should be the same length as a Mark V. The Double Tilt base and detachable arm was designed to replace the base/arm and headrest/tie bar of the Mark V. JPG, you would know better than I would if the 1960's Mark VII has different length bench and way tubes than the Mark 5 or V. I haven't owned one of the 1960's Mark VII yet.
I did see the the Mark 4 is available with the Power Pro Headstock too. Nice to not have the extra cost to change or upgrade from the conventional Headstock if you desire the Power Pro from the beginning.
