Keith,

I seem to recall that you bought some files from Otto Frei that you 
liked - perhaps the Valtitans.  Which ones have you tried, and what's 
your assessment of them?  I've been using lots of Micro-Mark files, and 
some others from jewelry suppliers and local hobby stores.  They all 
work fine, but if I could get some that last longer and load up less, 
I'd be interested.  Thanks.

My three go-to files are a Barrette in 00, Half-Round in 0, and Square in 0.  I have several other "yellow tang" needle files but I could get along quite well with just these three.  I also use a few riffler files but these are just from Micro-Mark.

This html message parsed with html2text ---------------------------Thanks. I may go for the "Equalling" file as well - it appears to be just a
rectangular flat file. Does the half-round have a file surface on the flat
side? Their diagram looks like it's smooth on the flat side and would only
file on the round.

There is a Link to the Otto Frie site in the Links - Tools and Materials area of the Mouthpiece Work Yahoo Group site.  Otto Frie is a Jewelry Tools supplier.  You can do a search on their name or a seach on Valtitan to find other sellers for these files.  
 
The half-round files I have cut on the round and flat surfaces.  I think the diagram on the OF site is incorrect.  You may be able to match up the file # to a correct diagram on another site.
 
Grinding the tips dull is a good idea to reduce gouging the inside of the chamber.  There is little need for a sharp point with our kind of work.
 
I may try heating and bending one of these files to make it into a riffler file shape.  I have a couple of dull ones to try it on.  These files hold up well for stainless steel work, but do eventually dull from it.

This html message parsed with html2text ---------------------------Thanks again. It's just [www.ottofrei.com](http://www.ottofrei.com) \\- pretty
easy to navigate the website. They also have a digital caliper on sale right
now, as well as some flex-shaft rigs (Foredom and their own brand). It's funny
that the files we need are the coarsest ones they have - I'm used to trying to
find the finest cut/grit/abrasive when shopping for tools!

Hi Keith

If you heat a steel file sufficiently so that it can be bent, you likely
will have changed the composition of the steel such that it is no longer
sufficiently hard to an effective cutting tool.

You may be able to re-harden it by heating it in a fuel-rich flame and
quenching it in oil. See the section on "carburizing".

 http://en.wikipedia.org/wiki/Carbon_steel.

I've used this method to create a small hard-steel peg that I needed, out of
a piece of common nail (which is pretty soft steel). But I don't know
whether you can restore a file to sufficient cutting hardness this way.

Regards,

Barry

Kieth,

If you heat & bend, don't forget to harden and re-temper.
