Mr. Grepper, thanks for the funny but interesting story how the Kellyrest was invented and manufactured!
Laser line reflected on a 2D convex surface consist of a bunch of lines reflected on the illuminated part of the blade surface.
Mr. Grepper thanks for reminding me the necessity to consider the blade tapper. The sides of my blade were convex with a mean included tapper angle of some 3⁰. This will explain major part of the observed difference!
The large yellow wheel is so called contact wheel and it is widely used in knife making. Its diameter is 10", and it is used as grinding wheel for hollow grinding or as a basic stock removal procedure before flat grinding.
After reversing the motor revolutions I use the contact wheel for knife sharpening also. Mounting universal support bar on the belt grinder allows me to use all my Tormek jigs.
