Okay, I ran into some problems getting the inner tube on the 36" wheel (the valve stem was far too thick to go through the hole), but a 29" schwalbe inner tube stretched out fitted just fine (and the valve stem looks much nicer imo), so the album has gotten an update, with the built up wheel in it, along with the front-left wheel to provide contrast. Next up: getting the cassette onto it, plus some 2d cad work to design the dropouts with integrated derailleur hanger.
