I don't have a dremel (anymore), so I used a razorknife to score it and just kept going a little deeper. It cut pretty clean, but my hand is sore from using it. Next time I think I will spray the scored line on the helmet with wd40 so the blade doesn't grip the plastic as much. It kept getting stuck when it went too deep. Also, a duller blade might help because it would be scratching into the plastic instead of trying to slice through it.
Thanks for the help SD68! The scoring probably made it alot easier and cleaner than just manhandling it and cutting some fingers off in the process.
Well, it is cut now, I am going to get the camera out to take progress pics. All I need now is some bondo and some for sale signs. I don't think I will quarter the helmet, as my head is rather small. Front to back, the helmet is dead on with WOF's template, and it is only a little off on the sides. Plus, it will be going to my stepson after it is painted anyway. After all, this is only a test to see how it will all go together when I make the real one.
