In this workshop report we will see all the steps to making a pinion by hand. This is how pinions are made for prototypes and small quantities without recourse to the automated machines for big quantities. Below we see the finished pinion, an 8 leaf pinio...
Thanks Don for the report. It is almost unbelievable that I remember using 'sacrificial' coal powder, heating metal to cherry-red, quenching and also annealing at metalwork class before I decided to become a heart transplant surgeon! I was young....what d...
