Thanks for the kind words. Although these have came a long way since I started this project they still don't, and never will, stand up to scrutiny under the macro lens. I really do not have plans, or time, to become a dial factory. I have been working on these decals so folks can get some decals from me and make their own dial. All that is needed is an old dial, some fine sandpaper, a can of whatever paint you want the dial color to be, and the decal. Once I get all of the bugs worked out of a few styles I'll post a thread showing which ones are passable. I Have the basic Snowflake pretty much finalized, the 7928, and will print a test batch of 7924 decals tomorrow. I also have a Space Dweller almost finished with a "Red" Space Dweller as a variation.
I have a few dials I could recycle, and might be talked into making one, but you are on your own as far as luming goes as I ain't no lumer!
As far as case backs go they have to be flat. The tracing was taken from mcotter's 1964 Tudor 7908 and his case back is perfectly flat. I have determined that the Cartel 5512 variety of cases has more than enough "meat" to mill flat and engrave. The back on this example is from a cheap vintage rep and barely had enough thickness to get flat. The gen case back is a bit over .050" thick while the Cartel back is around .100" thick so there is plenty to play with. You can look at your back and gauge how much curvature there is and if you have access to a micrometer you can see if you have enough thickness to mill it flat.
