The photo shows plans for building a 10 inch tilt arbor table saw. It originally appeared as a two part article in the November (p. 218) and December (p. 217) 1947 issues of Popular Mechanics Magazine. (The link for the second part of the article takes you to the front cover of the December issue, not to p. 217 and the second part of the article. See the second graphic. Enter "217" and press "Enter" on your keyboard to get to p. 217.)
To the right of the box with "217" typed into it are two blue forward and back arrows. The index for Popular Mechanics magazines is usually on about page 3. You can also pull down the "Contents" tool in the menu bar and see hot links to most articles. Oddly, the second part of the article on building a tilt arbor table saw did not appear in the contents menu, but I had to find it by advancing to page 3 and reading the index for the magazine.
While this table saw is very well-built and full-featured, building it requires some work on a metal lathe to make the trunions and other things. There is also some welding. It would be possible to have these things done at a machine shop, or by a friend with the needed skills and tools. It is also possible to buy a set of trunions for a commercial table saw on eBay. (The trunions allow the blade to tilt so that its exact axis is where the blade comes through the table.)
