This is turning the bore for the Polar alignment scope in the support arm in my lathe, the small green casting is the original, inadequate support arm/wedge mount.
The altitude adjustment is from about 43º to 60º, I live at about 54º so I have plenty of adjustment available.
The next part is making the base adjustment, which is a slightly clever way of adjusting and clamping the base down using a dovetail post. I have never seen this idea before so I have no idea how well it will work. Time will tell. All I need then will be a clear night, free of clouds. Currently an hour at midnight on Thursday is forecast.
