Big block is now a narrow rib. Weight loss in the transformation is about 27 grams. Upon closer examination of the big block on the cap, I believe it's main purpose was to balance/equalize the weight of the rods.
I've been machining 16 rods (6 race, 6 spare motor, 4 spares for balancing) during this adventure. All 16 of the rods weigh within 9 grams, 14 are within 6 grams of each other. I haven't started to equalize the end weights as I will be polishing the forge finish and have some hand work to blend the machined areas. I'm not sure how much material will be removed by that process, but I've trimmed about 75 grams per rod so far. After the equalizing, polishing, and blending I estimate that another 10-15 grams will be removed. That's a 85-90 gram loss on a 600ish gram rod (w/bolts).
Very happy with how everything looks so far, and can't wait to be done with the rods.
