The surface finish on this 0.640” hole in a test piece of aluminum (6061-T6) is absolutely incredible, especially considering the tool that made it: simply a 2” long piece of HSS cut off the shank of a reamer that was too long, ground down to a boring bar for use in the boring head on my milling machine. Just my luck, I’ll never get that finish on any bored hole ever again. (Don’t mind the piece of lint on the right side of the hole)
Not my usual post, but wow, a 60-degree, single overhead-camshaft V12, with crackle finish cam covers, and six, count-em, six dual draft carburetors. Not sure the application here, but likely a 3.0 liter. That’s 12 very small cylinders, each being fed by its own barrel, revving sky high.
Truly a work of art in its own right. Sometimes I’m down on Ferraris because their owners can sometimes be douche bags, but theres no denying the machinery is fantastic.
