I recently moved my Huot drill index to a drawer where, despite polishing the raised size markers, it's a bit difficult for my aging eyes to make out the sizes.
As luck would have it, a recent tip email from Machinist's Workshop had a helpful suggestion. For the fractional drills put everyone that's an integer multiple of 1/16 in point down. Then it's easy to locate the one you want. The integer multiples of 1/32 are midway between the upside-downs and the drills immediately next to them are plus and minus 1/64.
The email went on to suggest inverting every numbered drill that's an integer multiple of 5 and inverting the letter drills that correspond to the vowels.
My letter markings are large enough to see easily but the suggestions for the fractional and number drills appealed to me. However, despite having a high personal anality quotient, I just know I'd forget and put the drills in right way around after use.
However, markings corresponding to the scheme are easy to do. I used the white paint pen shown to put a dot by every n*5 number drill and by the n/16 fractionals. Now it's much easier to find what I need without undue squinting.
