I have couple of wooden plate clocks marked "MD" . One 30 hours, with wooden dial.
(this is big one 150mm*150mm guy)
Another one week-duration hooded clock
Marking here as ell, not best but can be read.
On previous two there also mark on drums "AF"
(30 hours drum)...
What is more common inch screw standart/sizes used in English (and not only) clockmaking? I want to buy some inches sized dies and taps.
looking on this tab: Tap Chart UNC/UNF Threads - provides tap sizes, drill sizes, pitch, (threads per inch) basic major diameter, basic effective...
