Well it looks like Dom's been busy again. Here's what he had to say.
Here are some photos of some of the 18" super scoopers I've just built.
Surprisingly quick and easy to build, although a little hefty moving
them around the workshop by myself... Made the curved sections by
nailing ply to curved formers (as suggested), which made the curved
section very quick to knock out, but also really solid.
Stuck some PD's in and stuck about 1.5kw into each of them and the
result was impressive to say the least.
