I was wondering if anyone has made a chart of handy conversions. For example a #30 drills a hole for a 4 size rivet and any other necessary items like this.
Cleveland Aircraft Tools has a nice two page foldout chart in their printed catalog. You could probably contact them and request a catalog or just one of the conversion charts as I think they usually enclose one when you order something from them.
Use a drill the next size up for each drill you want to store. (loose hole)
I have plenty of drill guides but the special aircraft stuff does not really fit (like ones with drill stops and the 8' long one for instance).
I made the above drill guide out of a piece of hardwood and marked the sizes. At the time this image was taken, that is all that was written.
But, to your point, by the time I finished the plane, the screw size was also written by each drill as a handy reminder.
The guide continued to grow with the addition of all my gun sets.
Yes, I had a handy pocket chart from Starrett or somebody but that was used very infrequently.
