OLD STEAM POWERED MACHINE SHOP 43 Designing a steam engine slide valve

#43 in a series of videos of my steam powered machine shop that demonstrates what a typical job shop of the 1920s might have been like. Today calculations are made to design a "D" slide valve for an early 1900's steam engine that I have been rebuilding in the shop. Machine work is started in the cast iron block which will be the valve. This type of work was done in thousands of small shops across the country 100 years ago. Questions, comments and discussion about steam power, old machine shop work, line shaft belt drives, etc. are always welcome here. Thanks for watching....Dave
