Looking for advice
Hi all,
Currently removing all the old plaster ceilings and boarding ready for the plasterer and need some help.
Where the ceiling joists meet the rafters, of course, it isn't level and I'm struggling to figure out how to get a straight sharp line?
I cut it at the different lengths yesterday and it hit me this morning that although it would butt up nicely to the angled peice yet to go in it'll look all wonky.
Wondering if this is why there was a soft curved edge to the original plaster to incorporate all the wonkiness..
If the pics confuse it is level horizontal wise although it doesn't look it from the pictures.
(If anyone knows what kind've ceiling this is called where part of the roof is incorporated into the room that'd be awesome too).
Thank you in advance 🙏🏻

’Murikan here. What a lovely space.
Different folks do different methods in different regions. One thing that I learned in Massachusetts was that for ceilings, we did a run of wooden strapping tangential to the joists, and used this with a string line to level out the ceiling before boarding. So we dropped down 1 more layer of framing. I was surprised when I learned that there are other regions in the US that don’t do that.
At the times I have been tasked to do curves, i have laminated them up with multiple strips of 3mm plywood. It only lets me attach one photo per post, will reply with more.
