The jig is simple and easy to make. Having a drill press makes it easier to get the holes perpendicular to the plane of the block. I practiced laying out the spacing for the hole centers by drawing a SketchUp model and working it out so that the diagonal formed between opposite posts would leave the desired diameter plus about 1/8" measuring from the outer circumference of one post to the outer circumference on the diagonally opposing one. You can make it exactly the same diagonal distance as the diameter of whatever ball you are going to use but I found that this does not leave enough room to manage the cord when wrapping. It's a trade off between the ball maybe slipping through the posts (have to make a set of wraps before inserting the ball) and having sufficient space for weaving without crowding the strands
Larger cores, of course, require more cord; but the larger it gets the easier it is to manage the cord as you wrap. I've done half-inch, one-inch, and inch-and-a-half steel balls and will try a billiard or golf ball next. BTW. The half inch needed 3 strands in each wrap, the one inch needed 4 and the inch-and-a-half needed 8 strands. I suspect that the billiard ball might need 11 or 12 strands and a golf ball (1.62" diameter) will need 5 or 6 strands.
