Unlike others, I use the Tormek only for establishing the primary hollow grind on my chisels and plane irons. I use water stones for the secondary bevel and final honing. This is a system that works well for me, and I see no reason to change. My instructor was David Charlesworth, and he posted a video about using the SE-77 for establishing a camber on plane irons, but in practice, he uses the water stones. I could never get the SE-77 to establish a repeatable or satisfactory camber, so I don't even try now. However, I use the SE-77 for all of my primary bevels because the small adjustments allow me to accurately dial in the grind across the iron or chisel.
My process for establishing a camber in a fresh plane iron is to grind a uniform 25-degree primary hollow bevel across the width of the iron. I use a sharpie to monitor progress and ensure I'm still grinding square to the iron. I'll stop when about 0.5mm of unground iron remains at the edge. I use the water stones for this last bit.
To aid in keeping the camber even across the iron, I divide the edge into four sections and put an index mark at each quarter of the iron with the sharpie on the side I'm not grinding. I also use the Lie-Nielsen honing guide during this process.
I use a freshly flattened King 800-grit water stone to establish the secondary bevel camber at 33 degrees (25mm projection on the LN guide). I work the outer edges of the iron first, and then move into the inner sections when I'm satisfied with the outer edges. A 1cm wide strip of 0.5mm thick shim stock along the edge of the water stone helps start the camber. I'll grind one edge of the iron by keeping the other edge on the shim stock. The water adhesion between the stone and the shim keeps in in place as I work the other side. As soon as the sharpie mark is removed at the first index mark, I move the shim stock to the other side of the water stone and grind the other side of the iron. When I'm done, the ground side of the iron will have two narrow wedges of freshly ground edge, with the widest part at the edge of the iron and the point of the wedge at the first index mark in from each side.
For a new hollow grind, this process takes between 8 and 20 firm strokes on the 800-grit stone, depending on how firm my firm stroke is. As the iron requires resharpening, this can take more strokes since the secondary bevel area is increasing with successive sharpenings. After eight or so sharpening sessions, I go back to the Tormek for a new 25-degree hollow grind. This takes less time than the initial hollow grind since the hollow is already formed.
I then flatten the water stone again, remove the shim stock and start on the inner portions of the iron. I use firm pressure on one side of the iron, on the inner indes mark, and take four to eight strokes on the 800-grit stone for each side. I check the progress of the grind to make sure the sharpie mark disappears uniformly and converges on the center index mark. When I'm satisfied with the grind, I go to the 10,000-grit stone for the final honing bevel.
I use the nagura that came with the 10,000-grit stone to establish a fine slurry of paste on the stone. I set the angle to 35 degrees (22mm projection on the LN guide) and make four to eight strokes down the stone. I apply light pressure on the edge of the iron starting on the left and progressing to the right as I complete one stroke. It doesn't take much effort for this and the rocking motion side to side is barely noticeable; however, it does make a difference on the iron. I use a 10X loupe to check my progress and ensure the honing bevel is uniform across the iron.
When I'm satisfied with the final bevel, it's time for the Ruler Trick (only for plane irons...never chisels). I use a 6-inch steel rule along one edge of the 10,000-grit stone and polish the back of the plane iron to establish a microbevel on the back. You can search for the Ruler Trick to see the details.
As Ken wrote, my bench planes, with the exception of my LN #51 Shooting Plane, have cambered irons.
