Progress has been slow during the summer.
I mainly worked on many details and little improvements everywhere.
On the upper I added 3 outlets, 2 in the front and one in the back for functions like the telescoping and luffing winch for when the derrick mast is attached.
I also added a couple of switches ( a toggle switch and a 3 position rotary switch) on the upper (2nd picture) to switch between functions. I have only 3 2-pole circuits coming through the slewing ring. This way i can switch between functions.
