You'll see the adjusting and working with a small shaping machine, a German GASTL RG200. The max. stroke is 200mm, i.e. 8". A shaper is quite usefull for producing slots, keyways, and internal toothing.
Nice video. I have an Atlas 7 from the 1930s. It is slow and mine needs most of the fixtures. It is the right thing for a small hobby shop. I bought mine many years ago and would like to find a better one but the prices are too high now. Good Luck, Rick
Oh yes, thanks for your hint. It is always difficult to translate special professional words from one tongue into another. For example: What you'll call in English a "crib" is in German a "Eselsbrücke" and if you would translate it word by word into English it would read "donkey's bridge".
Fwiw brand new industrial sized shapers are still being made in both India and China. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-x6DzS9Wk4jc.html as one example. I've heard a few rumors that some of them may be being built with cnc controls today. For the correct work piece there's still even a few modern industrial shops in North America using shapers.
It might look a bit 'Olde Worlde' but a shaper is a very useful piece of kit, especially for internal keyways, also if a cutting tool loses its' edge you can sharpen it up on a £20 bench grinder from Lidls, no need for a sophisticated cutter grinder!
With a well made shaper in proper condition, the correctly honed finishing tool with an operator that knows what he's doing for feeds ans speeds a shaper can approach average surface grinder finishes and accuracy's. You'd need a high end bed mill to get the same accuracy and still fail with the surface finish. Yes the surface grinder would be faster, but for the correct work piece shape and requirements there's still a few North American industrial shops making good money with them. So there not quite archaic yet.
