I'm progressing with the mapping. I think I can already make out a shape!


just a little addition to that, if you do decide to start taping mm rules to the shaft make sure it's only on the nut at the end of the shaft (or where the nut would be on an obs!!). you don't want to stick anything to the shaft that goes inside the sleeve cos you'll have a hard time if it gets stuck.pcad wrote:I use a $2 micrometer and a paper mm rule taped to the shaft. A normal mm ruler could be used instead of a micrometer.
