Before I began, though, I did some measurements of the bicep pieces. My flexed bicep is 10.5" (don't laugh, I told you I'm tiny). At the armor party, the consensus was that you should have about 1/2" of space around the armor and the arm when it's on. So I added an inch to my bicep measurement, which made the internal circumference of my bicep a total of 11.5". Using a handy Google calculator (because I never paid much attention to algebra in school TBH!), I figured out the diameter of the inside of the bicep piece for my arm. That came to 3.66". So that was the approximate diameter I was aiming for when reducing my bicep pieces.
I did some more calculations, and figured that I would need to remove approximately .8" from each of the bicep pieces. Since the pieces aren't symmetrical, I had to scientifically eyeball how much to take off of each side (I'm a fan of the Scientific Eyeball method). I squeezed the parts together, taping the right bicep pieces together, so it would match my calculated measurements. Sliding it on, it fit pretty well over my compression shirt. Yay!
So I clamped the bicep halves to my table and removed a little material at a time.
And then look at how much I removed! Trimmed down to my size on the left, untrimmed on the right. This looks so flippin' scary, doesn't it?!
But then when you consider that the original untrimmed bicep has a 16.5" circumference (5.25" diameter), and my scrawny arms are just a 10.5" circumference, you can see why so much needed to be removed. Take a look at the size difference!
I will give my trimmed pieces their own little spa treatment in a hot bath later to give them a better shape once I'm certain with the final fit and glued them together.
I still may take a little more in, but I'm happy enough with it for now to move along. Now to tackle the left bicep. Wish me luck!
