Brian,
I know I'm having a bad day, but your post really left me with a headache.
First, Hugh has written several books. So which one are we referring to???
Second, Did you rip the page out of the book and attempt to use it as a
jig?

?
Or did you photocopy it (or scan it into your computer)

?
Or maybe you just grabbed a compass and used his pattern as a guide???
As has already been said by others, maybe you used the wrong page?

Kurt, TomW, and others----this should have been locked because
Not Enough Information
I know the answer---this is a diary and anything goes!!!!
