I got a drill press second hand and found out too late that the nut that holds down the pulley above the spindle was missing. The two are connected via a cone and the M18x1.25 left-handed thread/nut pulls the cone tight. The manufacturer (Interkrenn) does not exist anymore and this type of nut seems to be unavailable on the market. Any suggestions on how to get the machine working without spending a fortune? #industry
