I have the stavepress and I work outside with it without a bench. I concreted a galvanized fence pole in the ground, removed the press from its stand, and put it right on the pole. I love it. As the sunlight angle changes I can swing the stave around and the whole press moves on the pole so I get the best light.
Its semi-permanent. If you want to move the pole just dig it up and fill in the hole. I keep a bucket over the press when raining or it can be lifted off and moved indoors.
Those stave presses handle a big piece of wood.
