Although I have never learned where they break, the Zamak headstocks and legs just have a tendency to break.

The problem isn’t the Zinc Pest that has affected maybe a percent or two of the other Zamak parts used on all of the 6”. Anyway, you would probably be wise to keep your eyes open for a cast iron headstock and pair of legs. He probably got a big Christmas bonus that year. And despite the fact that nearly half a century earlier they had already learned that similar Zamak parts broke. He also managed to change the legs to Zamak despite the fact that they only saved two probably horizontal mill machining operation and drilling four holes to make a part that had been in production since before WW-II and had never given any problems.

– don’t not yet know how to keep it save in the correctĭespite the fact that the cast iron headstocks had been in production for about 6 years years with no problems, around 1978 some probably not too bright bean counter at Clausing decided that they could save a bunch of money on machining the headstock casting and got permission to spend a bunch of money on the casting tooling and convert the headstock to a die-cast Zamak part.

To solve this, I will take of the head stock and align it better.ġ) 1) Take out the shims and level the bed.Ģ) 2) Align the headstock – I will check that by using a long unsupported thick rod clamped in the headstock and a gauge magnetically clamped on the carriage. The bed however is measured with a precision spirit lever far from flat, it’s twisted. It’s not the way to solve it in my believe but shimming (0.2 mm) the diagonal support feet the lathe works fine and I am able to get a diameter equal or better within 0.01 mm. It’s not possible to machine something (unsupported) with an equal diameter. Based on the manual, I believe the bed and the headstock are only bolted (4x). Until now I did not yet fully disassemble it. I own a 150 mm Atlas 10200 lathe (metric version of model 10100) and need to align the headstock to the bed.
