I have decided to do a very simple modification to my Charlie to allow on the fly adjustments ,in my case upto 125 mil ,but you can set it to anything really. I have made a fill in piece as seen in the picture which will be engraved with five lines for the different elevations. No more faffing about for me ! It will be very precise to adjust as it uses the existing adjustment screw and the engraved lines will work exactly as on a vernier so will be very repeatable ? I will post more pics when it's finished as I can only engrave one line per day at work
