Thanks Paul, The cables are a trademark of mine, started twisting my old speaker wire years ago with aviation twist wire pliers.
They allow you good control over how tight you twist the strands. Diameter is determined by how many strands you start with.
The weld seams are easier than they look. Just groove the area you want, mask off with
Tamiya tape and apply automotive glazing putty. NAPA $5.00.
Tool it with a dental pick while it's still soft and done. How 'bout that sling on the MP40!
