Thanks guys!
Prick your ears up, and in the distance you might make out the 'thud' of my jaw hitting the ground!
Great work, absolutely fantastic attention to detail. I take it you have access to a lathe and milling machine to achieve those results, not to mention some serious machining chops!
And yes, I have a lathe, but barely used it for any of that hardware; no, I don't have a milling machine; and no, I never did any machining before starting work on these parts. I did most of the work by hand (with files, saws, dremel, sander), and on my $99 Craftsman table top drill press (with a $99 X-Y axis milling-type vise). Oh, and one other critical tool...magnifying goggles. I found working with aluminum to be very similar to working with wood, only slower, and in much finer detail. It's a lot of fun, actually!
