Me and files have a hate love relationship. They hate me but I love them

I appreciate the sentiment Frank.

Like so many industries I suspect the foundry works are using other methods now for finishing out molds and cores.
In the past decades even die grinders don't get the love they used to.
CNC's have changed so many things small shops have a tough time getting seconds on good hand working and non-CNC tooling.

Like so many things that would be put to good use, I have seen large 'obsolete' tools that have been painted over, hanging on a wall or worse, rusting away in someone's tool cabinet when they could be doing good work in the hands of someone that will put them to work.
I try to save and restore and teach others to as well, (As I know many of you here also do)
