Hi 405th! I'm just about ready to resin the outside of my MK VI helmet, but I have another question. I was planning on putting a visor in the helmet (obviously) and so I pepped the visor as I was told to, but I was wondering at what stage do I actually cut out the paper visor? After the resin coat on the inside and outside? Also, is rondo necessary for every pep or is it just an alternative to fiberglass? Thanks for the help!
The visor is cut out AFTER you rondo the inside. Resin stiffens the paper, but does not provide enough strength to maintain the shape, and one of the main reasons to leave the visor in is to keep the helmet from collapsing, so you wait until the helmet is fully hardened (rondo or fiberglass). The other reason is that if you want to vacuum form, you need the visor to be the exactly correct shape for the helmet's hard to see imperfections.
Rondo is not necessary, but it is very helpful, and is not necessarily an alternative. There are three main ways to harden the helmet: fiberglass, rondo, and hybrid.
Fiberglass: Pros: Lightweight, very strong. Cons: Difficult to apply, Very prone to air bubbles especially around edges and recessed areas, air bubbles which can ruin the piece.
Rondo: Pros: Fast and easy to apply, great for sanding. Cons: Very heavy, brittle enough that dropping is not recommended.
Hybridding takes the best of both of them together. You pour a layer of rondo in first, that smooths all of the hard edges that make fiberglass bubble, and also provides a layer you can sand/cut into when you are detailing the outside (in case you break through the paper which many people always do), while the fiberglass keeps the weight to strength ratio high, and protects the helmet from cracking.
I am going to start a halo 4 build soon and i noticed that thigh is specifically for the right side. I was wondering how you can change the file to be for the left side ? thanks
