Whilst Father has been making up new governor weights, Steve has been working on the the other end of the mechanism. The governor shaft is in the bottom left of the picture, below the inlet camshaft position. As you can see, it is pretty rough and the two zinc arms which connect with the governor sleeve on the camshaft have broken off with only their bases remaining.
Steve measured what remained and then, after a look at the photo in the parts book, made up some replacements. These were a simple brazing and filing exercise.
The half engine yielded a governor shaft with a corroded but measurable lever on the end. After sketching it up, Steve brazed up a blank from which to make a replacement.
Interestingly, the lever is fixed to the shaft using a tapered cotter pin so two intersecting holes were required. Once the first had been drilled, Steve pressed a pin into the hole to support the drill whilst the second was done. This worked well and the blank was roughed out.
Some effort with a file to make the arm look like the original forging and that part was done.
