In my recent blog post about the transformers for my Fluke Transformer scene I had said "What fun it was gluing the insulators on the tops of the transformers (NOT!)".  I though I'd share a picture of an insulator on top of a penny so you could get an idea of the size (which is smaller than a grain of rice!)

I believe trying to glue 24 of these insulators on top of the transformers (2 each) just to make a scene more interesting may be a sign of mental illness.  What do you think?

I am trying to create sidewalks for a european raceway/layout. I used some parts of a retaining wall that I had molded out of hydrocal. See pic. This is O scale and I need to make my sidewalks wider for light poles. I also have a problem of trying to extend my sidewalk around a street curve.

Other than hydrocal/plaster, is there any material that I can use that will allow me to "curve" my cobblestone around the bend on my street. I also need to make a transition where the sidewalks meet at the corner of my street.
