> I have a set of miniature drill bits, but prefer using needles. I agree with Gregg. IMO, the best "drill bit" is a needle and I have used drill bits to make pinholes. My experience is that even a drill bit, which are calibrated, in other words: we know their diameter, won't necessarily make a hole with the same diameter, unless you have a very precise drill and drill chuck combination (my Dremel drill mounted on drill press is not good enough). The only time I use drill bits is if I have to make a very "big" hole (=>0.020"), I then make a hole with a 0.016" bit and work the hole until the desired diameter. > use. But I still measure the hole as I make it. Some good information > sources for actually making the holes are: > > The pinhole FAQ: http://www.???????/resources/FAQ/ > (just one source for FAQ) > Larry Bullis article: > http://www.???????/resources/articles/poke.html > more by Larry Bullis: > http://www.???????/resources/makingholes.html Once you have the hole made or even when in the process of making it, you could measure your pinhole with your flat bed scanner. There are so-so instruction on how to do that here: http://members.home.com/penate/pinsize.htm Guillermo
