Re the tight spot, it sounds like the check gauge is too narrow. Either the check rail has to go out, or the wing rail that the wheel rides up on has to go out.
I made a bunch of turnouts recently using 16.2mm gauge and had this problem at least once.
Those are the first turnouts I've made and I found it quite instructive to look really hard at what the wheel treads and flanges were doing through the crossing, pushing them through with the wheel out at the stock rail hard up against the stock rail and also hard up against the check rail. That seemed to show if there were any hassles with the crossing, and ensure the wheel going through the crossing couldn't ride up on the knuckle or snag the point of the crossing.
My turnouts were built using PCB sleepers so adjusting things was pretty easy. Not sure how you'll go with all those chairs glued down.
