Macro the old fashioned way, well, almost...

Just thought I'd share a shot I took of a 3/8" to 1/2" adapter that I recently broke.
I was looking for a way to see if it was my fault or the tools fault.
Shot with a NEX 7 w/5cm Nikkor-S 1.4 w/Leitz 30mm extension tube attached.



Comments welcome of course. This is SOOC jpeg fine.

This is an adapter for ??? Sorry but I am daft just trying to identify this but then, can I ever identify anything by name? I doubt it...as for your shot, it is clean of course.

(Just between you and me, what is your name?)

Very good image.

When I used to take similar images I found that some PP could vastly enhance what was not first noticeable with the naked eye. For instance, on this image I noted the line towards the bottom right and some PP revealed this even more;



Is that another crack under way?

As for cause, likely a brittle fracture which looking at the difference in colouring of the surface may have been under way for some time and finally gone now as a very rough guess.

It looks cast and chilled a bit quickly to me rather than forged - maybe. It certainly looks grainy.

Izzy - It's an adapter for a socket wrench set.

Grahame - It never ceases to amaze me what the digital camera can see vs the human eye. That very well could be another crack starting. Good thing Craftsman tools are guaranteed for life. Just walk in with the broken one and ask for a new one. Your PP on the pic really helps. I need to practice that more often.

John - I can't imagine a casting holding up to torquing which what this is used for, but, it could be. I suspect it would have lasted longer if I'd not used it to undo the lugs on my wife's CR-V. I do think the shop that put that wheel on over torqued it though, as I was only loosening it to re-torque it correctly when it broke.
