We've made plenty of castle tower roofs through the years. In the old days we did the math by hand, drew out the lines on a master template, cut, traced and then cut out the many pieces with a jigsaw. These days we build the files on our computer, send them to the cnc router and then let the computerized machine do the work for perfect results every time. It's a whole lot faster too. Assembly is a lot easier with everything lining up perfectly. The first of the Hazelnut Inn castle turret tower roofs is well under way and looking great!.
