Wow, came out nice. You must have access to some serious metalworking tools at your work.
Yes, I work as mechanic/machine-operator/more and have access to lathes, milling machines, column drills, etc.
And my boss allows me to do some private work when I have nothing else to do.
Reminds me of this wild use of Nikon Macro flashes...
Woah...
Thats no more a ring-flash, its a flash-ring, lol!
