Hi:
I'm a newbie to making model machines. Several of us in our club (Hamilton Model Engineers Club, Ontario, Canada) are going to build a David Croft design. In his article, there is a discussion of using fasteners with appropriate size heads, etc, to achieve an authentic look. His design uses UNC/UNF threads (2-56, 2-64 to 6-40). He suggests making up batches of fasteners to build up a stock for future projects.
I don't have any UNC dies below #6 and only a couple of taps. By chance, I DO have a set of BA taps and dies from #0BA to #11BA. I seem to recall seeing a cross reference chart somewhere that helped suggest metric v. UNC fasteners. (But I can't find that chart.) Is there such a chart for BA v. UNC v. metric?

(I think I want to make a Joe Pie knurled knob for the taps, too.)
