Nice set Shawn. Can I ask how the backs are attached to their supports? I see the dowels but no mortices in the exposed support so am not sure how those bits come together but am keen to learn. Always keen to learn. Thanks for posting the pics. Would be great to see them in-situ if you get the chance for another pic at a later date.
*ETA, after a bad run of heavily used pipe clamps, I gave up on them in favour of sash clamps. Not as quick to set-up but they don't slip like all my beyond-their-use-by-date pipe clamps used to.
