I would like to see this "Beer Can" setup, can someone post a pic? Might be handy when you in the middle of nowhere.

Personally I used my brakes and a pencil for years, and didn't think I needed a truing stand but when I bought my stand at a garage sale for cheap it was night and day better and now I can't go back.

Now if you guys have a easy cheap way to tension spokes I'm all ears.
