From the blog:
I've made several types/styles of wagons, and I've done a lot of experimenting with ways to do the axles, fifth wheels, hubs, tires, etc. As we proceed I'll go into some of the things that failed under use, were a pain to make, or were just good ideas on paper that failed in execution. While I have a very well equipped shop, I'll try not to do a "Norm" on you... "Now we'll just walk over to this US$5,000.00 piece of equipment and knock this part right out!" Though there are many ways to do any given shop task, I've tried to stick to methods for the average person to make a decent product without specialized tools.
