Yep it is my own design. Full pix and description here
New design soft top
It's still a primitive hood on sticks, but I've been told a lot better looking than the ugly type that encompasses the roll hoop. The idea is that it's weatherproof in winter/rain, but the rear screen, when removed, allows air flow in summer.
In reality with the sidescreens
and rear screen in, you can do 80mph, although the hood balloons and lifts 2" at that speed. Also wind roar is loud, but that's the car.
With sidescreens and rear screen
out, you can do 100 mph with no lift and almost no side flap. The rear screen offers unparalleled rearward vision and it fits nicely in the boot/trunk.
I like the screen up as protection from summer sun and feels very cool driving around town like that. I'm happy that this is the best design and is easy for anybody else and their trimmer to replicate.
PS The rear screen is 4mm stabilised acrylic. I bent the two curves over an old
oil drum, but you need to make a cardboard template to cut to and it has to be cut accurately which isn't easy.
