Woops! Totally missed the comment. No finished pics, as it's still in this exact state. When I eventually get back to this, I plan to dress up the top a bit and scrap the carriage. Hopefully I can spread the next set of tracks a bit wider and drop the whole thing down a bit. It'll still be on the beefy side, but I'll hopefully be able to tighten things up enough that it'll fit anywhere the actual model would. Once I've done that, I can start converting the Techmarine to have a full harness.
