On one of my local skip forages I came across this broken clock arm which was broken from its magnetic base. (unfortunately couldn't find the base )
Straight away I knew what I was going to do with it, make it into a clocking arm for the mill. So took my lucky find home and took the arm apart to replace the short stubby broken shaft for a 75mm long one. Unfortunately this ball joint was hardened so I chucked it into the wood burner which was roaring and left it in there overnight.
It worked, the heat was enough to make the piece machinable. So cut the old broken shaft off and drilled the ball to accept the new shaft. The new shaft was then silver soldered in place.
This now fits permanently on the mill and can also be easily removed and placed in a chuck to clock bores or diameters.
