Hi, I'm in the process of renovating a condo and have never really dealt with a staircase r ailing/banister. I see where the railings affix to the main posts and had no trouble unscrewing those but cannot seem to full understand how the spindles are embedded. It appears the rails act as a cap and have spacers that are inserted and possibly the spindles are glued but do not want to destroy the railing trying to get this thing apart. Does anyone know how to properly remove the spindles? Images attached. Thanks!
