Cornice/Scotia

Our scotia was a tricky one for us because we kept getting confused on how to ct i on the drop saw. Once we figured it out we were flying.

To put our scotia up we first had to put our bull nose on because it covered the gap between the pine lining boards and the sill of the window.

The scotia is measured by transferreing a line from the edge of our arc's down. and that is where the scotia lined up with so thats were you measure from.

You must place the first piece of scotia in so you can then cut your two returns that go on each end to tidy it up. Scotia is in many ways the same as cornice eg. the shape and how you must cut it. If you were to be putting up cornice in a timber home it would just be a large scotia mould instead of gyprock to flow with the finished look of the house.

Architrave's

The installation of our architraves was to a timber framed window in a timber framed wall. After we put our 130x12mm pine lining boards on our wall, next came the step of fashioning up a bull nose for our window.

To do this we had some ripped 90x35 in which we clamped to a table for a solid fix. Then we prepared a router to form the nose on our timber. We were required to wear full p.p.e when we were in the room using any power tools.

After we had made our bull nose and screwed it to our sill, we were ready to arc it. I started off my arcs by sitting them flat on the nose so they were hard down, and then transfered the mark from my querk to my arc and cut it on a 45degree angle. I placed both of the side arcs on then measured the distance accross from outside to outside of arc and cut a piece to suit inbetween.

once you have your arcs on give the mitres a sand to ensure all imperfections are picked up and fixed.

Skirting

Once we have built our walls and lined them with 130x12mm pine lining boards it was time to install our Arc's, Skirt's and Scotia.

I started of with the installation of the skirting. It was standard colonial timber skirting 70mm x 20mm.

We chose to place the piece down that would be first seen as you would walk into the room.

The first step was to measure the distance between the two end walls to determine the length of the skirting, once measured it can be cut. Before you apply the skirting you must walk around and mark all of the studs so you have a good solid fixing point besides the bottom plate.

When fixing to timber frame all you need is to nail it, when steel frames you can also noggin in between the studs or you can screw it off. If you are fixing to masonary it would e acceptable to se spaggeti and screws.We nailed our skirting on

Once the first piece was down, we could do our two scribes. To do the scribe you need to cut a mitre on you piece of skirt so it can be cut out with a coping saw.

Once it had been cut out it should butt into the other piece at 90degree's forming a solid and good clean join.

Installation of Wall and Ceiling Lining

Installation of Wall and Ceiling Lining
The first step involved in the installation of wall and ceiling lining was to prepare an area. We had to build a temporary wall each 2.4m long.

In each of the walls we built we had to allow for windows that were getting installed.

Once we had our walls built, in position and plumb, we started to noggin out for the pine lining boards.

I had to find the height where my boards finished and the plaster met and put a noggin on its flat all the way around the wall to ensure there was a solid fixing point for both materials.

I took a measurement and found centre, then plumbed a line down. This is where i started with my first pine lining board.

The first board is to go on the centre line in the centre of the board this way it will ensure when you get to the ends, if you need to rip a piece down then it will be of equal widths at both ends.

When you are nailing the pine lining boards to the framework, there are a couple of different options. You can nail it at the very top so the nails are hidden by the dado mould and at the bottom so they are covered by the skirting.

You can also secret nail through the joins which is more common when installing them to ceiling's.
