I will be installing a built up crown molding soon, I belive this is refered to as a cornice. It’s basically gona be standard configuration of upside down basemold, dental, then crown.
Which is the perfered method for installing this… would you build it up first on the benches, hanging it all in one peice, or, would you build it up a layer at a time on the wall?
Thanks,
st

Use short offcuts to template it so you know where one piece is going to sit relative to the next. Use that to establish reference marks, then tic mark it out on the wall and build it there. You'll have a far easier time fitting pieces one at a time, and irregularities in wall & ceiling have a nice way of being absorbed little by little with a built up crown.

RW is dead on. Make a test in the shop. Learn all of the dimensions and then put it up peice by piece on the wall.
What RW says.
I wouldnt want to try and fit the inside/outside corners with a build up, could be a nightmare.
I'd lay out all the lines ahead of time and install the mouldings one style at a time.

One stick at a time.
On long runs seasonal gapping of joints is common on quick installs. Especially runs on exterior walls.
Glue the bejezus on and behind the joints and glue/nail backer blocks behind the crown joints. Coping corners helps to allow expansion/ contraction at the corners and not the joints in the middle of the run.
Takes a few extra minutes but well worth it.

jesus ... we're just sticking a coupla pieces of base on a wall then filling it with crown.
just decide the reveal ... snap some lines ... and run the base(s) ...
then run the crown.
simple ... don't over think this ... it's just baseboard for crying out loud.
miter it on the flat ... miter it on edge ... run the crown.
