3 different magazine plans for metal lathe steady rests, as follows: srest_56.jpg is page 217 from Popular Mechanics magazine for May, 1956. srest_a.jpg is part of page 211 of Popular Science magazine for November, 1948. srest_1.jpg is the first page of a two-page plan from an unidentified old magazine. srest_2.jpg is the second of a two-page plan from an unidentified old magazine. A line of text is missing from the top of my photocopy of that second page. Sorry!
