Lumocolor ink permanent 487 works perfectly , best is the red color one , but black color works OK , I have use black as that more easy to supply , ink is available in 10 gramm small can . Any Staedtler pen permanent works also fine . To help to make accurate traces I use a print schematic made in Autocad , hold with adhesive tape and mark each hole with a steel point made by grinding the shank of a rejected HSS drill .
Yes it gives great results, I've tested it in the past. Of course it is a matter of personal preference eventually. Every technique has its pros and cons. I skipped to describe them all for short, limiting to tell what I use. I think they can be summarized as: - Laser printed (hot transfer): good quality but difficult to keep consistency - UV resist: excellent quality, a bit laborious - Direct drawing: poor quality, requires a bit of practice in drawing, but fast results - CNC router: excellent quality limited by the size of the router's bit, fast results - CNC laser: excellent quality, relatively fast results The CNC is obviously the best option, but one have to own a CNC router/laser :) Thanks for commenting. P.s. The video was an excuse to show the idea of using shellac to protect the circuit board.

Thanks for sharing.
we want to see lathe
Personally, I'd go with the UV-resist + overhead transparency route.
