Architrave round shrunken door linings

[MortarThePoint]

I fitted door linings before wet plastering and the plaster came level with the lining's edge, then. Since, the door linings have dried out and shrunk back to end up about 1mm to 2mm behind the surface of the plaster. How do I attach architrave?

 

Do I just glue the architrave to the plaster and then caulk the resulting crack?

If it is not too thin at that point how about running a planer over part of the width? It has worked for me in the past.

Not sure I follow. The wood is recessed behind the plaster

If you have / can hire a 'rebating' planer, then you just set that to take a 2mm pass down the back side, eg with the plane set up with the guide so that the blade doesn't take anything off the thin edge of the architrave.

Plane to a shape like this:

 

 

Door opening on right side, wall on left.

Yes, sir!

 

Don't drink the night before, it needs a steady hand lol.

For completeness...."hell no!".

 

And you need to have some brand new blades in the planer too. Set to 1mm, and do two passes, if you're not Norm Abraham

I was thinking it would be tricky

Not drinking? 

 

Well, ok, but that's a different website for that I'm afraid!

Relative piece of cake. Yes, what you suggest is what I was suggesting. If you have a guide on your planer it helps, but I have done it freehand before.

Yes, I might see if I can make a jig for my jointer planer to help save my fingers

Erm, assuming the door linings have finished shrinking…

 

Wouldn't running some sandpaper down the proud plaster simply do the job?  Feathering it in sort of thing?

 

The turn on the architrave might show depending on the profile, but if not I’d have thought it rather easier than machining so far across the architrave.

Please be reassured; 'freehand' in my previous post refers to the guiding of the plane(r). The architrave in question was clamped to the bench! There was simply no width-guide on the planer, but a line I worked to! All fingers intact!

The mitres will birds-mouth out then unless that is factored into a compound cut. Sanding the plaster down will be a bigger PITA and less controllable than planing the architrave imho. And dusty / messy as heck.

 

Planing the timber means no filling and sanding, where the sandpaper went astray, as it will for sure!
