This is the only shot tower in Australia which can still be climbed. It has wooden stairs supported by timber beams .
At the end of a very long climb you reach the top platform, where the lead was melted and poured through a metal sieve. The resultant drops fell through the length of the tower into a large water trough where they solidified into small rough spheres. These were then tumbled into a neat sphere and used as shot in a cartridge for a shotgun.
Fascinating technology from long ago. :)
@gilbertwood This is just outside Hobart - to the South along the old Coastal Road. A bit of a climb (well for oldies anyway - our girls flew up it!) but well worth it. :)
