yes, it's most important for the outer area to be smooth. Minor
bumps are not too bad. For instance dryer duct toeroids with their
corregations are not bad. However, a larger toroid is usually needed
when it's not smooth. A spun smooth toroid can be smaller for a
given TC and spark length. For instance, my TT-42 tc uses a
13" spun toroid, but when i used a corregated toroid, i had to
use a 17 to 20" toroid to get the same spark output.
