I’d hoped to completely finish trimming the loft this week, but still have base trim to go.
The top newel/end cap of the loft half wall consumed a LOT of time to make the trim and do the installation. I’d done some planning when I built the wall, but had not done the complete details of the build for the trim. Because I had planned for a rabbet to cover the drywall ends where it terminated at the newel core, I opted to use rabbet joints for both sides of the newel rather than 45 degree joints. A rabbeted joint provides more gluing surface than a 45 degree joint. The exterior box trim also has to be made just slightly larger than the core to allow fine tuning for leveling. Basically, this is three-sided box newel. The pieces were cut out, glue applied, assembled around the core, and clamped. Once the glue was dry, the final nailing was completed.
Shims were applied (using drywall cardboard shims) as needed to the top of the half wall framing to bring the area into level prior to adding the wall cap. The wall cap is 1 X 8 finger joint stock, bullnose on the router table. The newel cap was bullnose at the same time to match the profile. The wall cap wraps the newel to provide a decorative detail, as does the band trim under the cap.

Note the slight gaps around the newel core and the wall cap to allow fine tuning of level and reveal. No problem in paint grade work since these will be caulked and painted. But, it gets to be even more of a PITA with stain grade work.
Newel box and wall trims were assembled with polyurethane quick grab adhesive, wood glue, SS nails, and SS pin nailer.
