Has anyone built a sled for hauling feed and hay over snow? I used a child's plastic tobaggon last year, and it was just OK, only big enough for one bale, and it tipped over pretty easy. The advantage was it was very light. I'm thinking about making a sled from old skis (available at Salvation Army--they have hundreds!!). I could use 4 shorter skis, drill holes in them and bolt on a frame, then top with a 4'x4' piece of 3/16" plywood. My concern is the weight of this contraption by the time I get it done. How would you lighten it up? Will a ski hold up to having a 1/4" hole drilled through it without splitting? Anything else I'm not taking into consideration? I need to move hay, etc, about 100' down a gentle slope, and I'm picturing myself standing uphill/guiding it down to the feed shed. Thanks.
