How tach-y.

I’d bought a cheap-o Sun tach, 3 1/2″ diameter, to put in the T’bird dash where the original clock was.  Good idea, the face was white, like the originals, but it was BRIGHT white,  the originals have a yellow patina, the letters are bronze, where the tach numerals are black, and a different font.

With both gauges out on the bench, it was apparent that the dials were exactly the same diameter, and the sweep, or distance between the numerals, is VERY close to the same.  Why not use the new tach works behind the original clock face?

Hmmm, this gives me an idea...

So, after an hour, I had a new tach, with the clock face, mounted in the dash.  Kim immediately noted that the way I’d oriented the gauge,with the pointer where it was in the original tach position, put the rest of the dial “upside down”.  So, I took it back apart, and also pulled the pointer and moved it so as to have it rest at 12 o’clock, the new “0”.

What's wrong with this picture?

There, that's better.

There, that’s better.

Yup, that's it.

Yup, that’s it.

Now, I’ll take the rest of the gauges apart, clean the cobwebs and dirt from the dials, and paint the pointers red to match the new tach, and it’ll be done.

      The clocks original hands are bright orange. The speedo pointer and the other pointers are (I think) just faded. The gauge faces need to be cleaned anyway, it’s not a big job to pull them apart. it’s odd, but the bronze centers of each gauge are all very different colors. Must be the amount of sun they got over the years. I’m painting all the pointers orange to match the tach needle…

    Its details like this that make or break a build and as such I have always liked the idea of putting new mechanisms behind old faces
