This morning I had the double-swing-away mount far enough along for 'proving.'
After moving the lock-pin receiver,re-drilling the lock-pin penetration location,and cutting away the original pin location on the end of the mount I had what I needed.
The 1st swing frame pivot location would cause the tail to collide with the passenger side of the bed were it not for the second articulation built into the assembly,allowing the tail to ease away from the bed enough while swinging away towards the passenger side,exposing the bed cavity for baby's ingress/egress.
A caster'd pogo, inserted into the belly of the tail will take stress off the mount while swung open.
I'll pick up some 1/2" EMT before I get home.And use our community barn's slab to help layout the new tail geometry,even if I have to move the welder over there to tack it,saving the layout,then finish the welding back home.
The tail will need to respect the 10-degree departure angle,but I want the 2.8-degree diffuser section for DARKO.(the Beechcraft control surface pulleys can be re-purposed for that duty).
