Users used to send in their tips and there's a old compilation publication from all branches of WW.
Several pages on turning which are fascinating.
Someone pinched 's trick of using a hose (aka jubilee) clamp to set a regularly used depth of the tool post in the banjo.
The donut chuck makes an appearance.
Also a friction drive for finishing off the bottom of a natural edge bowl. Mount an old engine valve in a jacobs chuck, top with a disc of outdoor carpet and place the hollowed out bowl over it, with tailstock support.
To get an accurate spindle taper, mount the piece and turn the ends to the larger and smaller ODs, and rough out the rest. Then place the piece in a vice and plane a flat between the two ends; remount and turn down to just past the flat.
Elsewhere there's another take on this: turn the large and the small ODs. Count the turns on a caliper knob required to make the difference, and divide the distance between the two by the number of turns. Mark that figure by a series of pencil lines on the blank, and then stepwise down the length turn the depth with a parting tool increasing by one knob turn at each line. (Hope this one makes sense; easier but not legal to post the diag.)
