Just found and read this thread. I'm scared when Norm retires, a lot of old school parts will disappear, for example does anyone "print" Kinmont disc brakes or even a Harmon Collins magneto for flatheads and already he doesn't offer bodies to speak of anymore.
3D printing, I've spoken with a few and tbh, I can't justify the price of a printer, etc and though there's a lot of cool files on 3D Cult, etc I don't understand much about it. I am not really computer literate, I can Google search and I still use torrents for music (did I think that out loud?).
I'm impressed with what is there in aftermarket parts and some of the good resin casters still working. I also understand the financial end, though I'm not on a "limited" income, I am severely limited to "free" money as opposed to my financial responsibilities. I definitely have to budget out my purchases...
Just my limited experience and opinion and that and $8 will buy you a double mocha.
