Here's a raw enclosure challenge:
- a nice even cross-hatch:
The old Bugatti's are really stunning. This one's a 1926 Type 37A and the engine is hand-scraped while the firewall is engine-turned (as are often the instrument panels in the cockpit).
I used to have an even nicer example of hand-scraped cross-hatching on an engine, but pic must be on my old computer thus the linked pic above. If I could get cross-hatch by hand an enclosure to the Molsheim Bugatti standard, I'd be an extremely happy man.
The Pur Sang crew in Argentina do a pretty good job of replicating the hand-scraping of yore...
I've tried sanding cross-hatch by hand, but a bench-grinder worked better...
