Thanks Chris,
What I posted is just a mock-up so I could get some ideas or reactions from people here---the layout being my main concern. I don't have a geometric compass and yes...the spacing is not quite right. It was done 100% by eyeball. What really needs to happen is those numerical fonts need to be "shrunk" sideways to compress the width and make them more narrow, but that is easier to say than do. When time permits I have an open source program that was suggested by another friend, but honestly it is written a little over my head.
Of the two gauges I think the vacuum gauge is more relevant, but I have a 2 inch tach. One early thought was to only use the vacuum gauge and have it sit directly beneath the speedo, but the arc is different (shorter arc which travels opposite to the speedo needle) and it seemed to me like it looked better with the two gauges. But other possibilities do exist.
In addition to these two gauges, I am also going to use a red LED for the high beam indicator and two green LEDs for the right/left/hazard indicators. And there is also room to add a yellow (or orange) LED that would act as an idiot light for the alternator...if an LED will work for that purpose....and I still need to check that. Ideally it would need to be capable of running dim to bright and I don't know about that yet. Part of the LED thing is I'm going to try to come up with a way to make the LEDs replaceable without removing the whole she-bang.
