For my "someday" projects I have two mothballed WW80 headstocks. One that is totally gone, and another might be saved, but only after a feasible plan can be developed, based on the failures experienced on the first one. Though the measuretwice home shop facility is something I could only dream about, I'm interested to see where your thinking goesthe diagram you posted as got me thinking....
I have nothing to lose to experiment on the first and if that works, can perhaps save the second. Both have well designed deep oil channels from the gravity feed cups that preclude cutting the steel outers much farther. Having owned (but sold) one generic American headstock with soft (bronze) outers, it was amazingly smooth, almost with a vibration damping effect. So, I was thinking bronze (with its deformation tolerance) might be the best way out, but I still need a way to cut acceptably close short/small tapers in bronze and true up the spindle. It's a dream.
Yes. Thanks! They replaced their message board a few years ago and I suspect some of the original content was lost.it refers to an old BHI page I think.
My books are all in storage, but maybe there is something in Jendritsky, Perkins, Levin or Goodrich that I missed. Also, Tony, the machine archive guy in the UK seems to have met some surviving members of the machining families in Esslingen, but he's a busy guy and hard to reach. Levin and Pratecma are still in business, but it seems they don't make hard spindles anymore, leaving only Bergeon doing these. Perhaps the chinese have a good system, but suffer from their focus on lower cost production methods.its a shame there isn't more of a record.
