How to Build CROWN MOLDING-102 Part 4: Installing the Soffit

[This is part of my CROWN MOLDING-102 series.]

Installing these large, flat-stock pieces of mdf so that they match nicely is an exercise in patience, for sure. But I know you can do it.

In this installation I mistakenly did not account for having to cope the inside corners, but found an easy work-around to fit them together nice and tight.

My fasteners of choice are no surprise, they are my usual combination of Liquid Nails and 18 gauge brad nails.

The difficulties I encountered on this part of the installation stemmed from my installing the fascia and soffit together as a single unit.

I could have installed them separately, and perhaps that would have been easier.

Below Fixing my failure to cope the corners in advance was an easy enough.

All I had to do was cut away the fascia section that caused the interference.

Below Now a small section of the soffit has to be cut away and so I scribe if for removal.

Below My trusty Porter Cable jig saw made quick work of the cut-away.

Below I didn’t have any pictures of the biscuits I used on these butt joints. But I did. The biscuits might have been overkill, but I tend to err on the side of overkill anyway.

Below I didn’t want to take the slightest chance of these two mating surfaces being uneven, so I used a clamp to keep them in place until the glue cured.
