An impact hammer might work well on a vertical piano with low friction. But this assumes you will use standard tuning pins. What do you mean by "solid, stable front and back lengths?" Same total string lengths within a trichord should help with stability over temperature and humidity change. If this is a purely hypothetical piano, why not get rid of the front lengths entirely? Have the string connect directly to the front termination point. Ed S.
