A friend has ask me to make a pen from a watch that has a 40mm face … Any suggestions if this is possibleand if so what kit might help make this work?
If the face has to be 40mm then the pen has to be of the larger variety ie. Full size Gent, Emperor to name a few should work.
If my math is correct, the OD of the brass tube has to be greater than 12.7 mm minimum.
Could you share your math? I'd like to understand
