Tonight was going to be a long build evening, but my favorite baseball player, aka, my son...came home 4 hours earlier than expected...so the build evening is cut short and it is FAMILY time!
I just went thru all of the ribs and marked the part number with a sharpie on each one. Then I grabbed the 710 L/R ribs and ran the scotchbrite wheel around the lightening holes...yea, that's all.
Twice around the block and the lightening hole was deburred nicely...that part of the deburr process will be relatively easy...but there are a lot of lightening holes.
