Let's see if this explains it?
I start by soldering brass tube to brass strip. Usually after trimming to size/length, that's about it. On the engine cover hinges I still soldered brass tube atop longer strips. I then shaped some square brass stock for the basic 'form'. With enough contact surface for strentgh I did not solder the strap/tube combo to the square stock. I merely shaped it and affixed with CA. Look closely and it might be apparent.
