"......that took some serious thinking to make it work....."

You never really know on something like this until you have the parts in hand to see if will actually fit. It wasn’t so much thinking as it was a lot of “well damn that won’t work”

Pat’s suggestion about using a 3/4” wood dowel to replicate the shafts for mockup was a life saver. I could actually put sections together and check for binding and fit (there was a fair amount of sawdust floating around by the time I was done).
