The Pat Trap at my club throws uneven doubles the left bird is lower then the right bird.
The machine is level. The machine is a singles, doubles, wobbles machine, could use a little help with this
There is a little figure (about 6 inches long) way in the back were the targets sits that you can push forward and back. It might be tight, but push or pull on in to even out the targets. A little move goes a long way.
You want to lower the right bird relative to the left, correct? As paul says, move the "doubles finger" back just a bit and check your progress. The field will shift a bit as well (moving right, I think) so you have to tweak that a bit as well. It's a question of a bit of this, a bit of that, but you can eventually set a matched pair and then, knowing about how little movement will get you where you want, it's duck soup next time.
