Thanks! Really im trying to make it lightweight and comfortable. So plastics,im aware, are lightweight and are overall a large option, but im looking for a easier mold. If i could just find something that would fit these statistics not being a plastic, it would be great. You see, my Dad's best friend is a welder and knows what to do. He has a large varitey of rescorces, and is a great person in all to help me do this. So, he says that alot of pressure and heat are reqiured to do this. Im just trying to make it easier on him (and to also speed up the process). So thanks anyway, and will definitely be an option if all else fails.
