I was out spraying weeds today and came across an old steel wheel wagon gear I forgot I had. I had thought about using it for a display piece but then remembered the hubs are extremely loose. It uses a tapered spindle about 3" on the big end and 2" on the small end, maybe a foot long. There is an equally tapered hub in the center of the wheel, but it is probably an inch bigger diameter. The entire assembly held on with a cast washer and a 1/2 inch pin, and it is very loose. All 4 wheels are the same. I think these run on grease no bearings just like the old wooden wagons. But I can't believe they ran metal on metal so long it wore this much. Was there some sort of cone shaped wooden bearing in these that has long rotted away? Any hope for making replacements? Thanks
