heritance

Hi All, I am wondering if anyone has any direct experience with using Heritance Nibs on either the Jowo or Bock feeds. Is one better than the other? How is the fit? I know in theory #5 and #6 nibs should all be interchangeable, but I have not found that to be so. Sometimes there is a gap...

I need a nib, and can't seem to get ahold of him. I've tried email and telephone. Anyone know where he's gone?

I received an email this evening with the following proposition. I had not considered the advantage of having a die to make a mandrel for turning. Before I make myself even crazier than I already am, would this be a valuable idea? Would we be better off just having some custom mandrels made...
