That's a nice looking typeface.
Thanks, that's very kind. It's not good for body text; too serify...
And, yes, it's an awful lot of work, especially if you are unfamiliar with the way in which digital fonts are defined.
I started with the hand-drawn version (the grey scale image), then created the characters using PostScript stroke definitions. And then discovered that PostScript fonts are defined by outline. So I had to start from scratch and create outline paths that retained the fixed stroke width; that's not easy to do manually, and involved endless tweaking of Bezier curve control points.
I figured out the kerning tables by finding the letter pair combinations, many of which are the same, since the characters are based on common shapes (e.g. b & p, and d, g & q are an o with ascender or descender).
Then I discovered that TrueType fonts use cubic b-spline curves (with three control points), rather than Bezier curves (with four control points). At that point, I lost the will to continue. But it gave me great respect for people who do design fonts.
I'm an electronic engineer, not a graphic designer. I can't draw 'still life' or natural scenes, but I was always a good draughtsman, so fonts and posters have been my outlet. I've searched for a book on technical font design (with terminology, guidance/rules, process, kerning table design, etc) but never found one; they are always "here's a bunch of pretty fonts, created by <designer> for <client>, in <date>". There is technology in font design (even with the aesthetics), but the books seem to concentrate on the 'art' side.
