The mount is back together again, waiting for the pier which is primed and waiting for the finishing coats.
I am ecstatic with the finished product.
Due to the thickness of the paint removed, the index plate markings were no longer at the 12 o'clock position so I had to make 0.2mm shims to allow alignment.
No other problems with the assembly.
I hope to have the pier painted over the weekend and then reunite the mount with it next week.
Then the only thing that remains is getting the counterweight correct, at the moment it is about 3.5kg too heavy but I will wait till I have a diagonal and finderscope
attached before boring out some of the mass.
