Re: [atlas_craftsman] Curiosity killed the cat.
In the owner's manual, what is the information at top right of page 1 (which is the 5th page (counting front and back as 2) into the manual in three different model manuals that I have)?
FWIW, the one multiple-model manual that I have doesn't show a serial number range start. And the start serial numbers of the 3965, 3986 and 3996 are different, whereas the print dates are close to the same (1975 or 76). Which would seem to indicate that Atlas assigned serial number blocks to the various models before they were built.
Also, does anyone have Atlas single-model manuals for models or dates other than the following?
3965 December 1975
3986 October 1975
3996 December 1974
3996 December 1975
None of the Sears manuals that I have copies of show an applicable serial number range.

>My lathe is a 3996. An on line article indicated they were introduced in 1959. I haven't found any casting dates on the way foundation yet, but am still looking.
I too have a 3996, I have the original manual with it, that the owner
when he bought new, had put his name in the back and the date in the
back, I can only assume that was the date he bought it new as the son
in law said he had bought new some 35 years ago
he dated it 4-12-68 serial number is 101789
my atlas manual of lathe operations and machinist table still had the
original box it came with inside under list of reprints
reprinted from 38 through misc years till 1967 being the last year
noted inside my book
next page or so, it had a list of wall charts you could buy for 1.00
each, for some reason I think it would had been nice to have those and
I bet a dollar he had them but they were bought before I got to the
estate sale, the guy had all kinds of stuff
>The "Operating Instructions and Parts List" that I received with it indicates, on page 1, "December 1974 File No. 12AC with Serial No. 100200 to ______ (unfilled in)". My lathe's S/N is 104XXX. That info is as close as I know so far. I would be interested in seeing what that info changed to on later publications on the same page.
>The central question, is there is a date of manufacture chart, link or other form of definitive dating, by M/N, S/N (or other identifiable information)? I am just curious.

If you have access to a milling machine it is possible to carve a new compound-top slide from a block of steel. There was a neet magezine article about doing this work for a smaller Atlas 618 lathe in the July-August 2012 issue of "The Home Shop Machinist" by James Hornicek. He improved the strength of the slide greatly with his better design.
