Small Drill Sets

• When resizing jet orifices, you solder the jet closed and drill it out with very small drill bits. The photo shows two different very small drill bit sets that I have found available at some hardware stores. They contain #61 to #80 drills (.039 to .0135"), which easily covers the range needed for jets. I use a Pin Vise (as shown in photo) to drill the holes by hand.
