Question about TK "Teeth"

[Feltonbass]

Im currently working on the TK Helmet ( ATA ) and I have a question about the teeth.  should these be sanded down on the inside so all the teeth indentions are even with the inside of the helmet and then shaped?

 

Im using a dremel, but scared to go too far.

I'd use a triangular file to square up the openings of the "teeth". It's probably more important what they look like from the outside than from the inside.

I started to do that on my RS lid but found it too nerve wracking. What I found easier was to drill holes then open them up evenly with small files. I’m sure it can be done with a Dremel but as a first timer it wasn’t for me. I did attempt to keep the depth even over all teeth and I think I achieved that. Best of luck to you!

I use a dremel for pretty much all of my trimming except for the teeth, as stated before I drill in the corners of the teeth and finish off with files, much more control than using a dremel.
