I draw lines on a piece of paper with the divisions on it. So for 8 fins, I draw a "+", then a "×" so you have a pie with 8 slices. For 6 fins, you kinda have to use a protractor to make a 6 slice pie. Then I center the wooden wheel over the "pie" and mark around the wheel. I hope that answers your question!
Another useful one...except...do you have any tricks for accurately spacing the holes drilled into the hub?
