Back in the early days of (passive) surface-mount chip parts and thick-film hybrids (ca. 1969-70) I proposed a project to develop a non-contact soldering method for attaching e.g. chip ceramic caps (040 by 080) to thick-film substrates.  It would use a 5W or so CO2 infrared laser with servo-control of position, focus point, etc.  Management (rightly so in retrospect) thought I was crazy, so project never got funded.  However, that would have also been the perfect tool for "burning" your meter faces!

@antedeluvian: Do you want me to ship them?

I appreciate the offer, but I think I'll pass -- it sounds like a lot of work -- I think there are easier solutions :-)

If you still have an old flatbed plotter, a bunch of refillable pens for it, an old PC

I still have a Roland plotter, pens and ink (as was discussed in The Joy of Rotring) and an old PC. Autocad- I am not sure. Do you want me to ship them?

@cookiejar: After you do up your artwork on your PC, you can laser print it out on the the iron-on resist material intended for prototyping PCBs.  Then simply locate the transparent print  properly on the repainted rear of your dial and iron it on.

It sounds simple when you say it quickly :-)

@cookiejar: Nothing like using old technology for working on still older technology  -  a great make work project. ;-}

This sounds like a winner -- letr me know as soon as you have it up and running and I'll send you my meter faces for you to upgrade LOL

Iron-on resist

After you do up your artwork on your PC, you can laser print it out on the the iron-on resist material intended for prototyping PCBs.  Then simply locate the transparent print  properly on the repainted rear of your dial and iron it on.

What you are essentially doing is transfering the laser's toner from the plastic sheet on to your dial's painted surface using the heat of your iron.

If you still have an old flatbed plotter, a bunch of refillable pens for it, an old PC with an old version of Autocad and a serial interface for your plotter, a graphics tablet interfaced to your Autocad PC, you could enter your old meter face into Autocad using the tablet calibrated mode on an enlarged copy of your meter face.

You could then play around with some paint and thinner to get the right consistency for the pen to apply the paint to your dial.  It's also helpful to slow down your plotting speed if your Autocad driver allows that.

You could then apply shim material to the tracks of your plotter so the pen would be at the right height for the dial plus double sided tape.

You would then do a dry run on a piece of card of the right thickness and take measurements to accurately locate your dial.

You could then paint the back of the dial white and plot the meter face on it. 

Nothing like using old technology for working on still older technology  -  a great make work project. ;-}

I've actually seen a fair number of those around here, both of city streets and the freeway.  However, I'd say they're pricey for what you get.

Of course, I also see plenty of Teslas (especially), Leafs, and Volts around here; maybe if you spend a lot of time stuck in traffic, a full electric car makes more sense, since you're not using much energy while idling.  (Then again, a lot of people do 100->200 mile round trip commutes, which is stretching it for an electric).

@Antedeluvian: Forget a sidecar- I am having a mid-life crisis over one of these

Oooh -- I want one too!!!
