Step 1: Materials
I know! Let's make identification handles for my needle files!
What you'll need:
1. Needle files... I have partial sets, dating back 50 years, making for several duplicates. Very confusing.
2. Epoxy. I use the stick kind, but any type of moldable epoxy will work just fine.
3. Something to shape the epoxy with. Sander, hand file, sand paper or knife.
4. Dark paint
5. Bright paint
6. Permanent marker
Step 2: Dress the Handle
Because I only do one or two at a time, I usually put the needle file back into the foam holder at this point and wait until I have several wrapped before I go on to the next step. Doing them all at once would be more efficient... But then I'd have to think of something else to do with the left over epoxy from now on. After this Instructable I'll have 4 or 5 left to do.
Step 3: Shape the Handle
Finally, sand the top so the end of the handle is flat and looks like the shape of the file when looked at straight on.
Step 4: Paint the Handle
When the dark paint is dry, spray your bright color onto a sheet of paper and dip the end of the handle into it.
Set the file aside to dry.
Finally, use your magic marker to highlight any "special" conditions your files might have. For example, a dot to signify that the file comes to a point. I marked mine to show which edges are non-working (smooth).
From now on, when you need a particular needle file, you'll be able to select it without having to sort through them. This should work even if you keep your files in the plastic "wallet" they came in.
