Dang, saw the title and thought someone had a new backing to show off!
I just use a bathroom scale for checking weight then use the tiller tree for tillering. Got to keep an eye on both to watch for any hinges that may appear.
Had a bow break a few years back while my old fish scale was attached on the tree and had springs and dials flaying more than wood, so now I just use the bathroom scale. (my wife got a new one so I got the old one) works better I think because it's easier to see than from 8 feet away!
