[TheForge] Upsetter Dog (Cam) faces

[Bruce Freeman]

Do you mean, restoring the grooves?  If so, have you heard of the
technique of restoring files by acid etching?  Pickle 'em sharp!  Not
sure it works on cast iron, tho.

All of my tire upsetters have dogs (cams) with a toothed face to hold
the 
stock.  Most of these are worn to the point where they do not hold
well. 
These pieces are curved in one plane with the grooves running
perpendicular 
(straight) across the face.  These grooves are a lot like a file cut
because 
they engage in one direction.

What is the best way to restore the working quality of these short of a

milling process?  The material is cast.

Thanks,
Walt
