I apologize in advance for my costume OCD...
While at the make-a-wish troop yesterday, as we were standing in the room of mirrors I noticed that my arm armor was longer on my left arm than my right, by about 1 inch. Going back thru my photos I see it there now also. I fixed this problem last night.
My arm pieces are all attached, shoulder bell/bicep/forearm, and I was using bicep hooks. I assumed everything was aligned properly. But what I discovered is that the inner piece of the biceps are sized differently, 11cm vs 12.5cm, so using the bicep hooks caused me to attach the bicep to the shoulder bell at the wrong height.
So I separated the right bicep from the shoulder bell by pulling off the elastic strap, repositioned the bicep and reglued the elastic. I also removed both bicep hooks.
Now both arms are the same length.
Sorry this is so long but I though it would be helpful to other Anovos builders.
