The Witt DMC Caliper Timing Method

This note just acknowledges that Herr Dipl. Eng. Witt's controversial (I guess) method of finding TDC and placing the base plate at 32 degrees with a caliper is near-as-dammit dead accurate with some care. I read Piet's post re the accuracy of the method, but, as I am going through a "fully restored" bike and having found a number of things not as nice as I like, I had to check anyway.

The caliper method showed the Witt DMC base plate was placed correctly, but, I wanted to double-check with a degree wheel, which I did. About two hours of faffing later (my first TDC journey w. piston stop and degree wheel), I found the base plate was placed accurately.
