I decided to get busy on the rocker arm today. I wanted to go to a friend's and do it with a boring head, but that didn't work out, so I bored it with a fly cutter and got it to within .001". ( fly cutters make good boring heads, just hard to set.)
Once the hole was bored, I started to mill the end for the pinch clamp and slot it also.
I cut t he rough shape out on the band saw and cleaned it up on the mill.
After cleaning up on the mill, drilled a couple holes and masked it to be painted with the wrinkle finish. The next two photos show the rocker arm all finished and installed on the grinder.
Tomorrow I hope to get started on the micrometer adjustment for the rocker arm. the very last out board hole is for a counter weight. I wanted this brass , but a 2" diameter x 2" long piece of brass is extinct around here, so it will be made of CRS. I am thinking of dressing it up with a couple of bands of knurled finish. We will see how it looks tomorrow. I wanted the micrometer to be brass too, but it is way too expensive as it is 1 1/2" diameter and 1 1/2" long.( plus the largest brass found locally is 3/8" rod and they want $28 for three feet)
