Hi Dennis,

David T. Thanks for your efforts. Probably the biggest problem is that I am using Apple OS and am still on a steep learning curve even after a few years. The behaviour of that OS is somewhat different to windows (I gave that up with my old desktop still working on Windows XP media version). The Mac OS treats files/images in a different way and right click (2 finger tap with Apple on touch pad) does not give the same options as windows. I have tried quickly to copy, cut, highlight text and copy etc. but so far have not found a sensible way. the .img is recognised as an IMAGE and has different drop down menu commands available compared to other FILEs.
My little grey cells are becoming fewer and less willing to learn as the years months days go by......big sigh. :cry:
Back to the garage.....if I can find it!!

Yep I think I can make it work. MacBook Air gives somewhat different options but using the spirit of those instructions can save image to downloads then add file to reply from downloads (or wherever I chose to save it)...........just got to remember that now!

CAUTION Remember the caliper mounting bolts are M12 1.75, 14.5 tpi.........not to be confused with 7/16 UNC which has 14 TPI and slightly smaller diameter.

I wonder why M12 and not UNC chosen.

Because the callipers came with 12mm holes for an M12 bolt, not 7/16”?

I’ve never seen a 14.5TPI gauge Dennis - but have seen a 1.75mm thread gauge. Sorry, but it’s a pet hate of mine, mixing metric and imperial measurements. You don’t pick an M12 bolt an inch long, or fuel consumption is litres/mile?

Most of the laminated tables I have in the garage show TPI regardless of metric/imperial. Very useful to have all possible info including AF sizes.
I was just emphasising how easy the two bolt sizes were to mix up since it is very difficult to see the difference between 14 and 14.5 TPI. It would not help just saying 1.75mm pitch compared to 14 TPI? It is quite easy to think that a 14 tpi thread gauge is fitting on a 1.75 bolt thread or a 1.75 thread gauge is fitting on a 7/16 14 tpi bolt till you know the tpi of both.....after all a pitch of 1.814mm (14 tpi) is more difficult to compare with 1.75mm (14.5 tpi)?
I find I have to be bimetriperial nowadays.
But I know what you mean :D
