Needing something to more carefully shape panels over and following a friend’s great idea, I set about finding a section of old railway track. I collected a 14″ length which was only lightly rusted. I cleaned this up, neatened up the edges and rounded the corners. I removed all of the rust and smoothed the top surface. Finally I gave the non-used surfaces several coats of paint and the working surface a light coating of oil to prevent rusting.
