Re: Halo costume
Paper or foam? Yes, it's a personal preference, both do have their pros and cons. With my experience in work with foam armor, speed in building the armor is increased because of the bulk of the material. You have a product quicker but the detail is less. Pep work is somewhat reverse. You have to build up your thickness but the return reward is that you can achieve a higher detail in your product. If your are not too concerned about detail go with foam. If you want detail and have the time, go the Pep/fibreglass/bondo route. The end results can be outstanding.
Since you are doing a Halo costume, a great deal of info can be found on the 405th website. Not many halo costumes are done here..this is mostly a Ironman costume building forum....not that it's a bad thing lol.
Anyways, keep working at it, a rule of thumb when scaling or measuring for Pep. If you measure your forearm from wrist to elbow and find it measures to be 12 inches, your pep model will be 12 inches as well .....BUT..... The proportions will be off...your gauntlet almost looks correct but it's too short. You have to take inconsideration the elbow part, it usually extends past the elbow and provides protection when you bend your arm. In this case I would add more to your dimensions, if its 12 inches, go 12.5 or 13. Take this as a positive, I too am starting in Pep modelling...it's a great hobby.
Keep up the great work!
