Halcro, I was looking at this easy idea for those to try a remote armpod out which has been promoted here as opposed to your concrete idea. I can see having more sucess with this than the concrete.
Beyond Chris and Corby I don't think there has been any other DIY approaches so far.
Maybe you don't see it but I don't think that Gent would have mounted the tonearm if it wasn't solid or rigid and he solved the mass problem with the addition of lead. It's not the perfect armpod but it did allow him to try his additional tonearm with only a couple hours of work probably with basic hand tools. If a router is in your toolbox the job would be easier and could be implemeted a little better.
