thinking of making one, with a tire because i do not know many other ways and i want the cheapest one.
i ran into trouble pretty quick since tires are pretty light unless i manage to get a massive one, which i do not know how. i also thought about filling it with cement, filling a cardboard box with cement and putting a metal sheet under it. not very experienced in making a standard sled since i have no exp in metal working.
post pics or comment on your experience with making one!
