I''ve been working on a 4v design for a while now and have just finished a new design that is a much easier build than the conventional 4v that most people go for. I have a calculation tool here: standard 4v calulation tool The problem is that when you go from 3v with 2 unique panels up to 4v the number of unique panels jumps to 6, that''s 6 different jigs to make and some are scalene so you need to be careful to make them and fit them the right way round. I have come up with something a bit simpler.
This design has 4 unique panels and will section nicely at 25 percent of the sphere, this low profile shape is well suited to a larger dome floor area without going to high at the center. Ideally suited for domes 8m (26'') up to 20m (60'') diameter at the base. I''m putting plans together for this now and will update this page when they are finished but for now I can show you a couple of illustrations :
This one is for a dome of around 8m diameter
This next one is of a 14m double braced, so it looks like an 8v, still only 4 main triangle frames to build though.
If your looking for something big but not too complex then this design will work well, it''s the same construction method as all the other dome plans so if you''ve build one of the smaller ones you shouldn''t have any problems with this one, just don''t assemble it on a windy day!
