making the assemblies:
the leds have the lens sanded off to give more diffusion.
they are glued in with 2-component epoxy.

inside the meter housings. note the double led has to come in from the front.
I then glued the aluminum foil where the black tape was.

checking the current (thats for 4 leds in parallel !)
max for each is 30 mA so they are running very safe here.
I'm running the dial pointer one at 28 mA, with its own resistor.

the resistor assembly : 4 x 1k ohm in parallel for the 4 leds in parallel....(why 4 resistors ? better use just one with a bigger watt rating ! but thats what I had...)
and two 270 ohms in series for the dial pointer...
(the negative is common to all leds)
(I know I know it's all hanging in the air not very pretty, but it's quite rigid so I'm not worried...)

I'm very happy with the result.
And I did give the red line a freshen-up, it was all faded from sunlight.

I'll make a separate thread about all this plus the recap when it's done.
And sorry Orionkc for the thread hijack...
