Re: Gustav Becker Exercise Now a little side note about that errant hammer lever. Assembly for me went very smooth as wheels seemed to almost seek their holes and plate dropped nicely with smooth motion of wheels when I sat back, pleased, I noticed a leftover part; This is when I was glad I took the second picture. I just wasn't absolutely sure exactly how to position it. Satisfied I understood placement I commenced assembly again. This time not so smooth. Uh-oh. What's wrong? This time the plates refused to close. I studied the problem area and found it quickly. Make CERTAIN hook on lever arbor is seated between tension spring and seating cushion. Mine was resting on top of the spring. Looking GREAT now. This' beginning to be fun!
