Hello Don,
it looks great, .....yes the scallops were a little bit to deep.
Your problem is the aluminum wire, the aluminum expands and it's not strong enough.
At the beginning I wrote, I use a welding wire in different diameters. (0,8mm to 1,2mm)
The wire is on a role and is used for the Inert gas welding.
In many airplanes was installed a turnbuckle in the trailing edge.
I use no metal strip to hold the wire, it's not necessary because the wire holds without the metal strip.
Something else, don't do it with a spring steel wire.
Have a nice day,....Matz
