Hi Folks.
Though they are not true macro shots, I have some mechanical detail shots that seem to fit here better than anywhere else These are some jobs I'm working on (or have worked on) for proof of condition or just the customers scrap book, these are all from classic Triumph cars so the owners want their photos for the history file.
I generally have my camera and flashes on wall brackets with a timer remote so it is almost a timelapse situation and I pick the more interesting shots just in case you thought I was spending all my time taking pictures. ;D Some jobs do require hand held shots, there are fewer of those.
General layout of the gearbox.

Looking end on to the 1st gear laygear teeth to show they are not worn to points. I think the coloured Splodge is a nitryl glove finger print in oil.

Looking end on to the input shaft teeth to show they are not worn to points. I like this one for the Bokeh on the shaft that is sticking up. this is the item top left of the general layout shot.

Measuring the endfloat of the gear on its bush using a surface table and DTI.

A seriously worn timing chain with the adjuster about 1/8th inch from popping out.

Top the new chain, bottom the old chain, the degree of sag is a good indicator of condition.

Top the new chain, bottom the old one, if the sag didn't show the wear, the stretched length does!

The new timing chain installed and adjusted so that there is just a small gap on the tentioner just in case there is some excentricity on any of the new sprockets it will not go over tight.

These are all taken using a 20D with 17-85mm kit zoom using either 2 Triopo flashes set obliquely over the bench or one on camera for the engine shots.
Thanks for looking, I hope they are of some interst, I welcome criticism with the caveat that I'm fixing cars not running a photography studio!

;D
Cheers, Graham.
