My big fat head and Iron Man Mark 3 Helmet

[Grenex]

So I am about 60% done with my first pep of an Iron Man Mark 3 helmet and starting to speculate it is too small

I am using the file created by Sharkhead7854 and unfolded by Dubean33 at scale of 1.00

I have the back of the helmet completed, and when I put it on, it sits VERY VERY snug against my ears. I took this as a hint and did some digging around the forums to find the "Sharkmark VI - Iron Man - Helmet - Tester - Unfolded by Dubean33" file. I created that pep in a few hours and when completed the helmet BARELY fits over my head unless i wrestle it carefully. It basically stops at the area where I measure my head for diameter

You can see the comparison of the completed tester file vs the 60% completed detailed helmet.

My head diameter is 23.5" when I measure it.

So....I assume that with the tester file helmet so snug, I should scale up in size, but how much? Am I using the tester file properly? Should the tester (or any complete Pep file build) fit snugly on the head, or be tight when trying to slip on/off? I dont mind extra room, especially if I want to install gear to automate the faceplate, but I can not imagine wearing this without scaling up.

Thougths, IMpressions, shared mistakes, help....welcomed!

The helmet supposed to have the back panel removable so you can fit in easily. Some use magnet, velcro, and what I did is use pivoted hinges.
There are a lot of reference on how to do that. See my tips for what I did on the back panel.

As for your ears, it might help to wear a balaclava to squeeze in your ears, but comfortably.
