Jeff at Out Your Backdoor recreated his brother’s fast sled design this winter:

What you do is take a plastic tub sled ($10 hardware store) and screw a pair of XC skis to the bottom of it—if it’s a sled for kids—or a pair of metal-edge downhill skis if adults might use it. Use stout, short screws and big washers to avoid pull-thru. Then you glue foam-padding to the inside of the tub.

Apparently the only problem is that you can’t turn. If I lived in a place with snow, as I once did, this would be on my project list; great for recycling an old pair of skis! – [via] Link.
