I've always been fascinated by people's genius in developing their own training equipment.
When I was a teenager, my family bought new living room tables (the old ones were from the 1950's). The older furniture had conical table legs. Seeing the similarity with the arms of a mook jong, I scavenged them into my own version of a training dummy.
It's initial design was that of a large "T". It had 3 arms punching out from the shoulders (different from a traditional mook jong) and mid-section. Padding for the chest and head was made from old seat cushions. It had a single forward leg. I secured-tied it to a support beam in our basement. My first dummy was primitive, but I was able to explore the martial arts at a much greater depth than if I had always relied on a training partner.
By the way, I understand that some styles of choy li fut have a large number of training apparatus-training dummies; as many as 40-50+.
I'm curious if any of you ever allowed your creative juices to flow in a similar direction.
