Thread: Hercus production notes - historical

Hi Dave,

Thanks for pointing that out, like others, I maybe wander past the Hercus area once a week, glance briefly through the door, shake my head, and wander off..

The pre-springing of the lathe bed for a .001 convex curve is interesting, I suspect that all you would need to do is shim the ends and then the mag chuck would pull the center down, surface grind it like that, and when released, you would have a convex lathe bed...

Regards
Ray

Hi Ray, I do the same and thats why I posted the link here.
With the bed having the ark in the middle, do you think they just put the shims on the outside of the feet? Or something else.

Hi Ray,
Knowing almost nothing about these lathes. Would the bottom be flat enough to hold with a mag chuck?

I do like the tolerance part "if you write it, be prepared to explain it"

Hi Stuart,

Yes that was a nice dig at draftsmen who put crazy tolerances on drawings..

Don't know about the bottom of the bed, I'll have to wait for the DVD..

Maybe they just hung some weights off it?

You could assume when they ground those beds they gang ground them.... Get a whole lot of them up on the grinder table, then do them all at once...
