Well, first issue is all the geometry in the sketch is construction mode circles. So, nothing to pad. See attached.
Sorry - - - - disagree with your assertion.
Your blade is flat. The carbide teeth are the same thickness as the blade - - - - - also not true.
(A likely response is going to be 'it doesn't matter' - - - - except my shaft is likely going to have 70 blades on it - - - - that means an overall difference in shaft of some 28 mm if the teeth are 0.40 mm thicker than the blade body.)
Now if only there were an easy way to take your drawing and modify it to have the blade body at thickness x and the tooth thickness y and the number of teeth at z and the o/s dia of a - - - - - well life would be good (things are rarely that easy though - - - - I've just spent some time looking at your drawing - - - - - trying to understand how you did what and in what order and there is so little information so that one could figure out the steps inside each step of the drawing - - - - - this is where I'm quite lost in FreeCad).
(I think I could likely draw, using pencil and paper, an accurate drawing in likely 10% of the time I've already spent trying to figure out how to use the tools. The time was spent in that I want to use all the other tools but so far this has been quite time inefficient.)
