I seriously doubt if anyone is going to manufacture tooling to reproduce
any of these 1900 vintage threads or the tooling to maybe repair them.
Why? You ask. Because it is impossible to even recover the cost in time
and money to produce them.
Most of these feed screws and nuts are completely clogged with oxidized
oil, coal dust and ash. Proper cleaning does wonders.

Wonderful!and thanks
This info is a great background and a pleasant perspective.
We did carefully use a half-nut and were able to eliminate the damage which
was causing the problem however, given the softness of the mettle as you
mention, it is likely why our method worked.
Well if some "industrious" person ever manufactures thread chasers for
feeder rods, they would be appreciated.
Later
Bob,
