And here's the end result with the front panel put back on again:
Because of differences in the size of the old monitor and the new one, I've temporarily had to remove the Speed Selector Knob, which accounts for the small hole on the left side of this photo. Strictly speaking this should actually be positioned at the top right of the gauge, but that would put it right in the middle of the new LCD screen! A solution will be found for this later on.
There will also (shortly) be two new bezels made so as to finish this panel.
