Hi Grandpacoyote. I too applaud your layout and design. It's going to be a "grand" layout
The swingate is a really nice touch and I think you have executed its construction admirably, even if you do pronounce to have no carpentry skills, gotta disagree with you there
One small suggestion though to prolong the life of said gate. In image 002 I would add a small strip of ALMOST horizontal scrap/strip wood to the face of the main woodwork somewhere in the region of that writing and knot hole discolouration to act as a guide and ramp to snug the swing section up against the overhang as it travels the last few inches. (With the bias being a VERY slight LHS down to act as a lead in for the gate) Start the ramp inside of the main layout overhang so it does not act as a binding/ locking point.
This small addition will have the advantage of negating any slight warping or sagging due to wood expansion and contraction over time, temp and slight variations in humidity. Also any wear or movement caused bt the weight of the gate on the hinge attachment point and pin itself. It looks like you have something similar for the gate in the OPEN position in one of the other images 007 and 008 meant as a support tacked onto the underside of the benchwork in this case.
Can't wait to see more pics of your progress
