Ok, so I am finally getting around to making scenery for my layout and have decided to use 2" pink foam. I am modeling HO and want to make a small "mountain range" (more like hills but hey, this is modeling). Anyway, I plan to stack 5-6 pieces of 2" foam together to make the range (10-12" total height). My question is what have folks found as the best method to shape the top and sides of the mountains. I am looking for rounded tops and gently sloping sides. I've played around so far with utility knives and serrated knives but so far they tend to leave more jagged facings, similar to rock facings and not gently sloping tops. I am looking at the hot wire tools but not sure they can be used to make rounded shapes and such. Also I see where Wooland Scenics and others have molds that can be used. I have a couple of scenery books and have a couple of more on order but none of them talk much about the tops of hills and sloping sides when using foam. I see more of that with plaster and the like. Any suggestions folks have or layout pictures of what I am referring to would be appreciated. I'll try and finish my website soon so folks can see my layout.
