View Full Version : How are files made - history?

After CCWK,s ball bearing ??, I'm gonna ask about files. (Great answers on BBs, BTW)

I assume files were the next development after natural stones for sharpening, honing, and shaping.

I've read that they were adapted as first milling cutters, but how are they made? How are all the cutting edges raised, cut, or formed?

when i was younger there was an exhibt at the tallahassee junior musem in tallahassee fla. of some of leonardo da vinci's inventions and a file cutting machine was one of them. used a type of guillitine with a cutter striking the file stock, forming the tooth completely.
after being formed it was then hardened and tempered...jim

FileMaking - now there's a search term!!!

Search on file - you get everything but mill file.

Thanks, I've long wondered if they were formed in this way, hard to imagine (in this day and age) the labor required for a simple file. Files must have cost 2 weeks wages then, little wonder tools garnered so much more respect in the past. That and the fact that so much more skill was required to master them.

Oh, metal files, sheech, thought you were talking 'normal' computer files! Hehehe.

Of course, that is using the 'only' good computer O/S ... not the one that rhymes with 'doze'.

Oh, well

PS. Unlike the 'other' O/S, that command just ran on my system and would have run on the first system it was installed on in 1972. or there abouts. At least by 1978!!

There is a Nicholson file factory in Cullman
AL. Asked the local machinist training
center teachers at the JC about it and was
told they toured it twice but gave up---
fascinating place to visit but even with ear plugs and over the ear muffs it was too loud
inside for the class to tour. File tooth
punchers make a horrendous racket. Steve
