Coving help

[AdamD]

Got this very annoying gap to finish off with coving (used to be a hatch there for the loft) and not sure how to best do it. As you can see rather than a miter cut on the front facing wall it’s straight so not as easy to meet with a bit at the wall right angle. Could do another straight bit and fill but then the whole corner would look unfinished. Also the bit to the right is not perfectly straight which doesn’t help a new piece line up very well.

 

any ideas?

Bonjour.

 

Take the long length off all the way back to the corner, slowly and carefully, and fit a new section with the external 45 cut into it. 

 

Same for that bit left from the other 45.

 

Use Tupret filler to match & patch and you're off to the races.

 

Use a padsaw to cut along the middle of the coving, then use a bit of wood and a hammer it strike the bottom edge up, and the top edge in, to remove the U/S bits. 

 

This will save you trying to join older profile stuff to newer profile stuff on an external 45 which would be a royal PITA.
