In the mid-80s whilst on MASUAS my QFI (Uncle Rod) arranged for me to visit a buddy of his who flew at Binbrook. I spent half a day being shown around the radar bay and recall a radar on its test stand radiating through the big window.
On one of the benches was a drill that spun a piece of wood (about 2" x 3/4" x 18") along its axis. As the wood turned they wrapped a length of uninsulated wire round it. After this they would cut through the wire along the length of the wood on opposite sides to produce hundreds of U-shaped pieces of wire. These were then used to wrap around the multiple pins in the radar boards to link them together.
I'm sure they told me that they used to have to buy these links from Ferranti before they found the much cheaper in-house solution!
