This is a great tutorial, and after reading through the comments on this thread I feel that I have learned a lot on scaling.
I tend to overthink things, so if I am making this more complex than it needs to be, I apologize.
When scaling the helmet, I assume the height measurement (if done perfectly) would be the exact height of your head. When I apply fiberglass and resin to the inside of the helmet and padding, I assume that this will create a requirement to increase the height to accommodate for the increased thickness on the inside of the model. Is this correct?
If so, what is the average buffer that you would apply to the height? I was thinking one inch (1") would be sufficient for any fiberglass/resin and padding. What have other members experienced? Am I overthinking this?
Thanks!
