I like the idea of having clicks on the side wheel but I spent ages sorting that one out,,
Finish setting your wheel up in yrds until you are happy they are right. Turn your wheel to the limit of its travel then put a mark at that point. You can then remove the wheel and place it on a piece of paper and draw around it transferring your marks to the paper including the limit of travel mark. Then you can wipe your wheel clean apart from the limit of travel mark and remark it with your click chart. All you have to do is replace the wheel with the limit of travel mark on the pointer and your done.
