Those are always fascinating to me. An old friend of mine, who is a Master Quaker Carpenter was on the team that remodeled Benjamin Franklin's house and a nearby gristmill powered by water. Principles are similar. Back shortly after I retired, I apprenticed under him learning carpentry skills for about 2 years. Best two years I ever spent, I think. One of the projects I had to do was assist in building a horse drawn cart. He built the wheels that were spoked and I had to do the rest. Had to do the everything, including the axle with hand tools only. Did the axle with drawn knives. Wish I still had photos of some of those things we built. They got lost in a shuffle somewhere.
