idu_idontunderstandExploring some of the opal mining heritage items at the #AustralianOpalCentre's shed. This stuff was in the background of the latest video, YouTube link in bio. This is an ingenious design for a puddler, a machine for washing opal dirt to find the opal inside. It appears that the driveshaft of the car can be detached and swapped between driving the car and running the machinery. Very cool! #opalmining #lightningridge #miningheritage #opalminingheritage
