Moderator Art Posted January 16, 2013 Moderator Report Posted January 16, 2013 Put your laundry list on Marketplace, the leather related stuff should sell. In your post, are you saying that a Consew or Ferdco shaft will stand up to a file and that a Juki won't? Given that the average mill file is in the 58-62HRc range, that would be one hard shaft. The Ferdco machines were manufactured on the Consew, Juki, and TA-King base machines, and I can guarantee you none of their shafts were hardened anywhere near 56. You don't harden any shaft that high as any impact would be rather dramatic. Hardness is employed for wear resistance, corrosion resistance, and sometimes for compressive load along the axis, but not ever in shear capacity as in a shaft. Hardness is used in special circumstances, not for every part in the machine. Ferdco left the business I suppose because sales lagged. There was too much profit taken, and the other dealers ate their lunch. When they went from the Juki to the TA-King, they saved a considerable amount and didn't pass it on. They could have went to China (mainland) and procured machines at a cost that would make them competitive, they did not. Art Quote For heaven's sakes pilgrim, make yourself a strop!
