Here we have a replication of the roadometer. There are several versions out on the web and some debate as to the actual design. I followed one of them put out by a professor at BYU who did some extensive digging on the subject. The wagon wheel turns the shaft one rotation every six turns of the wagon wheel. The large gear tracks a single mile and the small gear tracks up to 10 miles. There is a little 4 tooth gear behind the large gear that I attempted to take a picture of.
I was asked to help build a puzzle to work in conjunction with the telling of William Clayton and the building of the odometer. This was for a pioneer trek put on by my church (The Church of Jesus Christ of Latter Day Saints) once every 4 years. The kids walk 12 miles in 3 days pulling and carts on a really challenging horse trail filled with challenges like tons of mud among the only hills in Indiana. It was really rainy this year and there were lots of blisters. I heard there was lots of exhaustion, some people passed out, and other various injuries along the way. There is also a very spiritual part of the trek and it is a great way for kids to connect with the early members of our church and the trials and faith building experiences they went through.
I thought I would venture to recreate the odometer in such a way that the kids could put it together and play with it during one of the lessons they are given during the course of the trek. The couple that asked for my help like the idea and they came over on a couple occasions to help the work along. The gears come off if a dowel is pulled from the back. The screw shaft can also be dismantled by removing a dowel.
I included a picture of the short version of the story that was read to the kids. There is a more extensive write up on it HERE about half way down. Just search (ctrl+f) for “odometer” after you click on the link.
