Just looking for some tips on trimming outside bullnose corners. I believe that the corner is a three piece (one each for the adjoining walls, with a third short piece mitered at 22.5 degrees and set at a 45). My question is how to/where to set up the short piece so that the 22.5 degree angles join the wall pieces properly. Any thoughts or techniques?
TIA,

It depends on the thickness of the base and the radius of the bullnose.Take a piece of base and put it in position extendingpast the corner and draw a line on the floor. Do the same again for the adjoining wall, and then hold it at a 45 against the bullnose and again draw a line on the floor along its face.
Now you know the length of the short piece and where the miters belong. If you can't draw on the floor then put a piece of masking tape down to draw on.
You'll still have to adjust the miters for the mud and bead build-up at the corner, but this will get you going.
If the top edge profile is thick enough, I like to hollow the back to fit the bullnose on the front roller of the belt sander. Do this first as it will change the lengths of the pieces when installed

Thanks a bunch, Rich - that's exactly what I was looking for!Cheerz,Greg
They also sell a preformed radius for this depending on the base profile (check with the mfg). Cost wise well worth it and a better end-product IMO (they're only app. $6)
Same as rirefalo does.
This gets you as close as you are going to get given the drywalls and framers may not have have all things equal to start with.
Watch for the fingers when cutting the small pieces!!
Also I have taken to using the "Trim Glue" available now and simply gluing the small pieces into place. Easier than fighting split pieces from the nails.
