Thanks to a great effort by TJ Ridings, I have hooked up with Mark from Crooked Blanks. He has glued up a couple of hollow Spherical Revolvers. It has ribs running lengthwise instead of the typical struts going crosswise.
There are some minor kinks to work out, and it is still a balsa blank that has to have all of the irregularities leveled out.
More on that project later.
