Forming Methods Vol. 3
This latest volume looks at presses and dies, not the huge ones with complicated dies, but smaller crankshaft or hydraulic presses, both using simpler, easily made dies. The first section, on presses, is less likely to give the model engineer ideas, but the second half, on dies, does contain a lot of useful info, including formulas which indicate how far you can bend various metals without damaging them. Plus you get details of making patterns and dies from various materials, including plaster, zinc, Kirksite, Dural and concrete. Good stuff! 152 well illustrated pages. Paperback.
