Today I cut out the hole for the shoulder hub detail. I made it 1/16th of an inch smaller than the piece itself to obtain a snug fit (honestly it measured really close to 3-3/8ths at the widest so I made it 1/16th smaller for good measure. You can always sand off more, not less). Of course I had to test fit the detail pieces that will go there. Fits like a glove.
And while I was at it, I also drilled the 3/4" ankle bolt holes.
Next weekend I will focus on finishing the arm pits.
