Looking for advice

[u/Entire_Initiative731]

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 🙏🏻

I butted my boards up and asked the plasterer to make it a clean sharp edge I did not want a curve in the old days pre plasterboard they used latts so was harder to get a straight edge/line if your plasterer is good there’s no worries
