JIM, Brad's curved turnouts help make for smooth juncture of any rate of curvature. These various tracks were laid out to blend without regard for the need to conform to any stock radii turnouts. The rail heads were paper traced which guided Brad's fabrication of this flowing throat:
Turnouts can be made to allow slicing in half for lift outs. Note also six of Brad's custom radius fully soldered curve "Snap Track" sections each with two pair of color coded soldered leads which provides for stable curved ROW at lift out. They make a quick precision drop in installation for a curved lift out.
Joint track is laid into Aileen's wet adhesive, weighted and left to dry. Then using a flex drive Dremel the joints are cut with a slight lift out angle which provides for smooth operation.
