Hi Tony,
I hadn't set my sights on any particular type, just whatever comes up. However I hadn't (until now) considered making my own. Strange, because I have every possible tool available to man and spent 20 years running a woodworking business!
What timber did you use and did you design it?
I used spruce (fairly knot-free, but not entirely) and finished it with a layer of biaxial cloth in epoxy and 2 component polyurethane paint.
Yes, I designed them myself. 200mm diameter at the partners, tapering to 100mm at the top, and a taper from the partners down to the mast foot. I scarfed up lengths of 80 x 80 spruce to the desired length, cut an angle off the inside corners and glued (all epoxy glued) them together to make one piece 160 x 160 with a 50mm hole up the middle for cables. I them glued some boards on the parts that needed to be thicker than that, bringing them up to about 200 x 200 and then set to work with the circular saw and planer, cutting the square section to a tapered octagon and then planed to round cross-section with the desired double taper.
With the wonders of hindsight, I can say that it was all really quite easy and I'd do it again that way. I just used a long straight edge to see that the tapers were even and they've turned out really quite well.
