Thanks. I have a lot of materials(pipe, angle, flat stock), I'll think on it for awhile. My only expense to date is for the wheel, and I guess the steel from the scrape yard @ $.10 lb, and a few sticks of 6011. Wood, bolts, etc. are from my accumulated "stock"(some might say junk). As far as my time, well, this is a hobby so it doesn't count.
