I made several batches of similar style training weights for a personal trainer who was a former ADF Commando running a boot camp style program. The first batch were painted black. A few weeks later he asked if I could make another lot but this time paint them yellow and put a sticker on that read ‘Training Weight Only’. As a part of his brand he would run the classes in DPCU, him and six paying clients were bailed up in the street by Police because some muppet reported a gang of armed paramilitary roaming the streets.
