Hello,
Can someone out there tell me how you tell if a file or rasp is sharp
or if its ready to be scrapped. Picked up a couple handfulls of files
and rasps at a garage sale and do not have enough experience to know
if they are sharp enough. Is there a way to look at the edges of the
grooves or something?
Thanks a bunch
Bob
So does a file card. Thats what its made for. The comon wisdom was is to not
use a wire brush as they are made with hardened steel. Of course, it
natuaraly fallowes that people would start saying that about a file card do
to their ignorance.

I don't know...Probably so if you use them daily and have 15 or 20 that you
go through.

Bob, those files can be sharpened. If you contact Steve Knight you can
probably find out from him where he sends his files to be resharpened. IIRC
he has NEW files sharpened before he uses them.

as long as it is a good file it is. anymore I have them sharpened before I use
them. the difference is pretty amazing. it is about 75% cheeper to get them
resharpened. anymore new files are not sharp to begin with.

AND.....never use a file card on a file, the wires are much harder than the
file and will only dull it.

It is also a good way to get sharp flecks of metal in your eyes,
fine particulates in your lungs, or toxins into your bloodstream,
if you aren't careful.
I could hardly believe it when I read that the anthrax at the
Postal Sorting Centers went airborne because the workers used
compressed air to clean the machinery. That has been verboten,
for just that reason, for decades.
That's not to say Steve is not careful, just a few words of caution
to all.

you do have a point. I never have to clean metal out just wood. and I always do
it facing away. that's a easy lesson to learn (G)

but you have to find one after you put it down (G) the air nozzle is faster and
does a better job if you have good pressure.

a air compressor works well.

Out of curiosity, is it cost effective to sharpen a file, your more
common run of the mill type file, otr cheaper to buy another?

Excellant point. I'd never thought of that although I use the air gun
on everything off facing away from me. Have asthma so dust irritates
lungs .

It used to be said that you could drip them in Nitric ACaid to sharpen
them. It actually eats off the rounded off corners. A file often can
be used on copper and non-ferrous when it can't be used on steel.
Old rules:
1) Only use one file on one type of material-NEVER switch types of
materials being filied with a file.
2) You can go from filing steel to copper/brass but not the reverse.
3) ALWAYS rub chalkboard chalk on a file before using it on aluminum,
brass, copper, tin, lead, etc.. It fills in the gullets and allows
you to take a card file and brush the chalk out and reuse it.
4) Never oil a file; it allows the steel to slide over the surface
instead of cutting it; once it has slid, it is ruined.
5) Chalk and file and oil it. Keeps it from rusting. Just use a
degreaser to clean it up BEFORE you try to use it.
