Awkward angle

[hamd01]

I wondered if one of you guys could give me some advice about cutting plasterboard at an awkward angle. Well not so much the cutting but the measuring.

I need to cut some board that will fit around this beam on the ceiling. As you can see in the photo I have boarded up to 2.4 metres high, and now need to measure and cut the piece that will sit on the wallbabove where I have already boarded, with a cutout for the beam.

If anyone has some recommended tools or techniques for doing this I'd really appreciate it. The boards are 1.2 by 2.4 so I'm envisaging that lifting it up there to get it and place is going to be very tricky too, does I'm doing it on my own I can't see a way to get it up there and draw lines in situ.

Any advice greatly appreciated.

A few ways to do it
Make a template with cardboard. You can tape together then transfer shape to board.

Or watch YouTube..

The way I’d always do it is:
Pick a point where you want the board to start and finish, such that the joint is staggered with the boards you’ve already fixed
Mark those points along the top edge of the existing boards
Measure directly upwards from both points to ceiling, subtract about 5mm for wiggle room
Cut new board accordingly, with those measurements. So first cut to total length, another cut for left edge height, and another for right edge height
Job done.

Except for the purlin notch, which again measure start and end point of, along edge of board, and cut out. Doesn’t have to be exact as you can fill it.

Re. Difficulty lifting the board, doesn’t have to be a massive piece, just plan your staggered joints accordingly.

Thank you really appreciate that.

Once you’ve hooked it round the purlin notch, it’ll sit on top of the existing board, which will take its weight. so it’s not like you need to support it when fixing other than just a hand against the top to stop it falling down.

I'm sure you'll figure it out, but I have to say that's proper DIY boarding, a man after my own heart, a "pro" would have fixed that with about 7 screws. And you don't seem to have broken the paper even once, fantastic!

Measure and cut the triangle, ignoring the purlin notch

Then measure from the sharp point of the triangle to the purlin, and measure the same on the plasterboard triangle

Then mark out a rectangle the size of the purlin(easy measure) plus 5mmall round the rectangle

Cut the long sides of the rectangle with an old knackered wood saw, then score and snap the short side of the rectangle

Lift into place and adjust
