привожу вместе с коментом:
"I get a lot of questions about how many time I put in to these things. Well, this is the first time I kept track of time.
I worked on these rings 26 hours.
and then I mean:
Drawing out
Mill the MDF
Saw out the aluminum, milling, and ...a lot of milling
a little bit of "filing"
abrading and a lot of abrading.
cleaning and polishing
quickly making a set of 4 rings, LOL"
