How do I finish these plaster corners around doorway?

Is it possible to give me VERY simple instructions on how to finish this doorway? The walls are Lathe and plaster. Links to the products I will need would be so helpful. Thanks in advance. Name:  12571270_10153486806656775_2035026941_n.jpg

I'd recommend you put 1/2" sheetrock on the jambs then use a metal reinforced paper tape corner. Mud the corner with 90 min setting compound to fill the gaps between the plaster and the drywall. Then once that's dry, mix up another batch and bed the paper corners into a coat of wey mud... push the corner firmly back onto the outside corners... wipe the edges down tight... squeezing the excess out from behind the tape. Once that's dry, coat the corner with the 90 min mud and a 6" knife. Once that's dry, skim coat the corners with regular joint compound and an 8" knife.

Everybody has their own way of doing things.

I like metal corner bead instead of paper covered corner bead. I also like to run a layer of tape/fiberglass over the metal edge (not the corner) to reinforce the bead if it ever gets hit. I have watched guys demo out bead done this way and it is a PITA. Makes for a strong corner.

I only recommended the paper because nailing on a metal bead (through the plaster) would not only bend the nails... it would probably break off even more plaster. Paper corners don't need nails.

Thank you so much for both of your responses. But wow, I guess I'm really out of my league here, because its like both of you are speaking a different language.

Is it possible to link to any videos that might be helpful to a very new beginner? I put up drywall and mudded the seams in the rest of room, but that didn't have any exposed wood or corners like this. And it wasn't lathe and plaster. TIA

Sorry for another question. I've been googling what you've said. Is it correct that I cannot put the corner reinforcers directly over the wood jambs? I need to screw on the 1/2" drywall first, then the corner things?

If the plaster is proud of the stud anywhere trim it back to flush. You can cut the new drywall to fit the width of the whole jamb including the plaster if you go with square corners. If you use bullnose make it the width of the stud.
That video says about all.

I normally just use staples to attache the bead. However I didn't think of the plaster aspect of the project. Yeah, paper would be the better call.
