As for my projects....
First is the polar rtr engine I started by shortening the gap of the tender this turned out to be very simple. By just drilling a new hole in the draw bar from the engine to reposition where the screw attatches.
Second was adding a more realistic coal Load this was just some of woodlamd scenics coal glued over the top of the exsisting molded coal. I laid on dry first to see how I lked the look then a layer of elmers glue was applied and spread followed by a light covering of the coal material.
For those nervous to try any of these. Take your time and don't be scared.
