That's a lovely-made diagram Ken. Would you know why 55° was chosen to be the standard? Just wondering if there is some aesthetic reason that particular slope was decided upon because I was just reading a comment posted by
@supxor in another thread where he chose 40°:
"I decided, too, after Bill [Lilly] and I measured his degree of slant, that I wanted mine to be to his: 40 degrees. I was interested the fact that the norm for slant at the Zanerian College was 50 degrees. I prefer the severity of his current degree slant."
I've also seen exemplars where Madarasz used 45°.
What is the advantage/disadvantage in using a different slant?
