[AT] Crankshaft Manufacture

I have to agree about getting paid by the piece.  

Back in the early 70's I watched a gentleman in Paterson NJ regrind a flathead crank.  A small shop in Gasoline Alley owned by Pappy Hough. He was an artist and the goto guy in the local area for midgets and sprint cars.  I was building a motor for my 41 and was referred to him by a friend.

> Hi Bob - sure, you're welcome.  The only part of the process I've really seen is the grinding - it looks just like that in any modern engine rebuilding shop.  I could imagine most of the rest and not be too far off.  I like the offset chuck setup used to turn the crank journals.  Those lathes are pretty ancient, but they're keeping them running,  and the requirement for precision comes only at the end, with the grind.  That's where you see some real attention to measurements (versus mostly rough measurements and go/nogo tools in the earlier processes).  And as Spencer noted, these guys know what they're doing.  Their pace and movements suggest to me they get paid by the piece, not the hour.  You can see there's no OSHA in this part of the world, wherever it is.  I've seen other videos on this channel that are pretty clearly Pakistan (dirt floors, child labor, open chemicals, no PPE...)

Of course there are a few jerks who pointed out some of the things they are doing wrong.   So far I haven’t seen anything but 100% effort and results considering the conditions and the strong likelihood there was little if any formal  training (that’s actually just a supposition in my part). So IMHO the negative comments were completely misguided and out of place.  Nothing real nasty but clearly along the lines of “the little lights aren’t twinkling“ (If you haven’t watched the movie Christmas vacation then that one will fly right over your head)

Some of the machines and fixtures might even be the very same ones from many decades ago.  (For Cecil Bearden - this is a Belarus crankshaft).  And if you don't have 40 min, you can set Youtube playback speed up to 2X.  You won't miss anything.
