Funny: I did the same thing about six years ago, but decided that an optimistic speedo might (that's might
) cut down on speeding tickets. Largely, it works.
The only problem I had was getting the needle off in order to replace the face. The needle is pressed on to the post, but once you take it off the meter movement will rotate to ~6:00 position, though not accurately enough to be a reliable indicator of it's position. Although I did not replace the face, I did come up with a way to remove the needle while keeping the movement in the correct position when reinstalling it. Simply stated, I ground the tip of a small hemostat to fit between the needle body and the movement, then using a piece of old circuit board drilled it to locate the pegs on the movement, glued a piece of wood of the correct thickness to serve as a base for the handle of the hemostat, let the needle rest against the stop, clamped the post, and clamped the hemostat to the wood. When removing the needle the movement did not move, so when the new face was installed the needle could be pressed on against the stop post. Never used it, and I could not tell you where it is now. Sorry. There is another way, but it requires an adjustable square wave generator to drive the needle to a repeatable position without using the original face.
I am including an attachment of a JPEG of the face I designed. It does not include KPH, though it would not be difficult to add it, or as the primary scale.
