WE STILL DO. Got a loft full of Triumph Gt6 bits.
Who do I contact to have a few thousand 80mm Planar front elements 3D printed? I can also use 500C aux shutter clock springs.
For really small parts it doesn't take much power to remove the necessary raw material. I once turned a wrist-watch balance cock in a clamped DIY power drill. Amazing how quickly a swiss file will reduce the diameter of a spinning piece of 3mm high-carbon steel rod.
And equally quickly bend the tiny pivot you've carefully shaped!
The Vincent (motorcycle) Owners Club started a parts supply project to keep those bikes running. I believe they are still going but in the early days (when I owned a Vincent) those parts really needed a machinist to finish and fir them. BTW, I believe you can buy a complete replica Vincent these days, made in France I think, but they are very expensive.
Yes. Balance staff.
My internal dictionary is becoming dog-eared with age.
At the moment, I've got a 3D printed crank on my SQ-A, a 3D printed lens board on my 4x5, and a 3D printed battery box on my GX680. I've got a nearly indestructible 2-slot 120 film holder that's also 3D printed. A friend has a Chroma Carbon Adventurer 4x5, and about a third of it is 3D printed. At the end of the day, though, most home 3D printers are making plastic parts, and those have limits. Laser sintered is a bit more durable, but it's not going to match a CNC machined part.
Gears and cogs are relatively easy to reproduce-- take an accurate photo while it's laid out on a gridded surface, load the photo into your favorite cad package, and start tracing. Once you've got the 2D part down, the 3D aspect is frequently just stretching out the 2D model.
The problem is that you're tracing a worn, or broken part-- and that's where you need an expert who can come in and restore the 3D model to "new" condition so it can be machined, printed via sintering, cast, etc.. Jay Leno's restoration team does this sort of thing to replace broken car parts on a regular basis.
