This is the wedge sitting on the top plate. There is a slot for the azimuth adjustment. It can be seen at the back. The top plate must now be drived for the stud pattern of the wedge. Top plate is 8mm thick.
All steel components are a minimum of 8mm thick. Drilling of the holes will be undertaken by Metal Fabricators P/L with precision equipment. They assure me that the bottom plate and the secondary plate are within 20 seconds of 90 degrees. Best to get everything as close as possible right from the start.
The hole has been set of the north south line that I set up several weeks ago on the side of the wedge when I had the scope set up in that area.
Pier cost $500.00
Comments and questions welcome
