Replacing or adding hardened counter combs

[treemuncher]

Where can replacement strips of counter combs be obtained? My Seppi head has significant wear and the parts manual does not even show this as a replacement item. I might also want to add some to other cutter heads.

Does anyone have a source where I can order hardened counter comb bars?

I had some cut out at a steel fab shop. I used 1/2" AR400 for my Fecon.
