Nah, just kidding. Would be well worth having a go. I haven't seen an exploded view of one, but I think there would be a fair bit of work involved. I'm a first class machinist by trade, so would be very interested. Post plenty of photos and give a good description of what you do if you decide to try.
The Adverrun looks quite achievable. Need to cut spur gears and make shafts but I am set up for that. The Brenner system is more elegant to my mind but needs a high level of machining.
