I think Bob really meant it (0.0001") but I don't think it is available,
thinnest I've seen in catalogs is 5 times that (0.0005"). IMO, 0.001" is
more than enough for pinhole making. I regularly make pinholes using 0.002"
and only use 0.001" when making pinholes for under 20mm focal length. The
smallest pinhole I have ever made is 0.0045" which is "optimum" for a focal
length of 9.7mm!! (according to the formula I use).
