Hi there, in my opinion you are all focussing too much the wrong axis of the plane blades. For a carpenter's usability it's negligible whether the grind is flat or slightly hollow. Some of the best planes, equipped with Aogami steel blades are reversing the position of the blade with the grinded side upwards. Then the only difference is that you have to bend the planing chips with lees than 1/10 mm of thinness about 2 degrees more. Important? I don't think so. However, the difficulty for me when grinding a plane blade on a Tormek is to achieve a really really rectangular edge with the SE-77 jig. I know well how to adjust the jig, and also have the precision square tool to measure, but I only notice any aberration of the edge after having grinded away some of the precious steel. Even worse, this has to be adjusted with every new mount of the blade. For this type of usage, the SE-77 jig alignment appears not to be precise and stiff enough, in my opinion.
Any ideas on this?
