Review on UGEARS Mechanical Wooden Monowheel Construction by Seth Gomez

This is my second fairly advanced UGars kit (the other being the Grand Prix Racer) and I really enjoyed building it. These kits are great therapy for aging arthritic hands as well as good mental stimulation! However, I've removed the large drive wheel four times already, each time sanding and waxing the surfaces it interacts with, but it still gets stuck and won't move on its own. The internal mechanism runs smoothly without the large wheel attached. Maybe one day I'll rip it up again and grind and wax it more aggressively, but for now it's another noticeable oddity on my shelf.
