Today I put together a pdf of the first couple dozen pages of my 1950 PM Shop Notes compilation. There are some very interesting plans and info here for the workshop enthusiast.
The first is a great jig plan for a shaper sled. The second is a very complete article on vapor zone grinding including plans. For the wood machine purist the third is a massive 24" disk and oscillating spindle sander, completely made from plywood. For the metalworker with a vertical metal cutting bandsaw, there is a very good article on cutting complicated shapes that rival castings.You will also find a few other good ideas for around the shop.
