Easy PCD This tool allows you to quickly mark down a pitch circle diameter on, for example, a flange. The "centre" piece bolts to the "plate" piece. Thus the tool is self centering on a flange. As long as the centre hole is accurately machined. The location of holes required can then be marked off. The centre sections provided are sized to 40mm-43mm. The plate gives a 4 hole pattern, at 20mm - 60mm in 10mm increments, in addition, there are markings for the diameters +3mm and +6mm. i.e. 4 holes at 33mm, 4 holes at 56mm are possible, along with other permutations of the sizes marked. Sketchup files are provided for any alterations you may require. If you make anything using this tool, post a make with your item and any further ideas and/or suggestions.
