At this stage the block was at a lean 4.55 ounces down from 8.85 ounces. I imagine when all is said and done and the teeth locks are ground in, it will weigh in at 3.90 ounces or a good 1/4 pound plus per side shavings not including the back plates and screws.
Should be about a pound off at the end between both doors. I'll take it.

This stuff is starting to make me wonder about my sanity or lack of. LOL
