“Then imagine how many machines and jigs would be needed to make this old school.
John S.”
John S is spot on there. When I had to work for a living the place where I spent my time made some very complex parts. Some of them required up to 18 different operations and many changes from lathe to mill to the fitting bench and back again, there were inummerable small jigs and fixtures as well. All with their own inspection stages and opportunities for stuff ups. Then we got a new machine that did everything….bar stock in, finished part out, no jigs, no fixtures, one (big!) inspection stage, the machine paid itself back in under twelve months from memory. Those parts were not required in huge numbers, from memory batches of six or eight prevailed.
Given a robust well proven data pack (this may require several prototypes to sort out drawing issues), a workshop or workshops with the appropriate machinery there is no reason why a competent range of small/medium, widely specified lathes and maybe mills could not be made for a sensible price. The issue then is to match the design and manufacturing sophistication (and therefore the retail price) to the anticipated market.
Interesting discussion!!
