Cooper-since you are not building a scale model, don't worry about the small details. If you hadn't mentioned the small rollers I probably wouldn't have noticed. I think the grousers (being thick and tall) looks worse than the small rollers. But that's just me. Everyone has an opinion. Make the model to please YOU. Since you will spend hundreds of hours over this model you will know every little mistake that is made. Most people won't notice. I always said to look at a machine from a side-view and pick out a few features that stand out and try to make the model accurate to these features and you will have a good looking model. But remember, a model that looks great but doesn't work is useless. Try to make something that looks good but works GREAT!! You are doing good, keep at it.
