HI everybody, First off let me say I model On30 and I love it!!. My question is about Trees. Though I know how to model them I m lost on how to do so in O scale. How do I make a Tree 4 (O scale feet in Diameter? ) 1" Dia Balsa Square Dowels is Rare to come by not to mention making a forest of them would cost a small fortune to do. Is there another way to do it? Below is a picture of a HO scale Tree made from 1/2" square balsa.
