Advanced Help requested with cornice scribe and coping on very small corner

Hi all,

I've read thru all posts here regarding this subject and watched quite a few videos on this technique but none covered this issue.

Pictured is the very top of my front veranda post where it meets the ceiling.

The red trim on the right is 3 meters long and has been butt joined between the two posts.
The idea was to manage all the fiddly work (scribing and coping) on small the pieces.

The red trim on the left is 2.4 meters long
I have NOT nailed this left piece as yet.
and my plan is to also butt join between the the post pictured here and the brickwork on the front of the house.

The Issue:
If you look closely at the picture, the depth of the post on the left side is smaller than the trim.
About 5 to 10mm.

How should I approach this issue if I am to butt join the long trim on the left?

The detail piece on the right is a scribe and cope cut on the right side
and I believe a 45 degree miter cut on the left side.

But the left piece I can't work out in my head spatially.

Any serious positive constructive suggestions regarding this issue would be greatly appreciated.

Barry,
You need to leave the piece on the left on the wall, and cut another piece for around the column as if you were cutting an internal mitre. Make sur eyou leave this piece nise and long to make it easier to hold.Then follow the line that the 45 cut makes along the profile of the mould.Try it for fit .Once you are happy, then cut the external 45 on the other end.

I think this is what you were asking.

Sorry to back up a bit.

I've just realized I've got a compound miter saw.

I've found this definition on the internet.

Miter Saw motors are mounted on a swing arm that pivots left or right to produce angled cuts.

A compound miter saw can be adjusted to cut angles both vertically and horizontally,
this is especially handy for cutting crown molding.
The compound feature allows the angle of the cutting blade to be changed relative to the horizontal plane.

What plane, vertical or horizontal, does a standard (not compound) miter saw cut on?

I believe vertical.

A person stands vertically.
A person lays down horizontally.

A vertical cut is always straight up and down.

There are standard vertical miter cuts:
90 degree cut, 45 degree left and 45 degree right cuts, 22.5 degree left and 22.5 degree right cuts.

Again, All 5 of these standard vertical miter angles being cut straight up and down on the vertical plane.

With the immediate post as a basis for my analysis.

When the instructions for a coping cut describes a 45 degree angle,
as demonstrated here:

and Here:
http://www.thisoldhouse.com/toh/vide...181576,00.html

would it be correct to deduce that this 45 degree angle is for a
standard miter saw set to 45 degrees?

I'll break out the Compound Miter Saw today and have a play and post my results here.
