I think the final answer would be getting the solid decks made in China BB, but not until people have some confidence in the design and detailed construction. It seems to me that the best way to do it is to make a few accurately in Australia by hand - and quite possibly several different members will have a go at it. From the Outdoorking point of view, it is best to have the full design details available to all members so they have the choice between doing rather a lot of hand work, or buying one properly made - but they aren't going to prefer the bought ones until they know quite a bit about them.
We all know that when Victa transferred nearly all their manufacturing to China, most people think the quality suffered. Most people also think the more-or-less SB45 copies made in Asia are inferior to "real" SBs in various ways. These impressions may not be accurate in detail - for instance, I've been very surprised at how good most chondas actually are - but you can't expect people to accept Chinese SB parts without proof of their quality. We know that many things are made well in China, and many are made badly. The trick is to know a lot about the item before you buy it.
