These lovingly hand-crafted by me… in my garage hammering the little brass rivets into place with a proper hammer, just like the proper Ancient Greeks used to do, but without the garage.


I make 2 other sizes - medium:180 mm (measures 35 mm to 320 mm) and large:400 mm (measures 80 mm to 750 mm)

I can make other sizes if requested.
