This is a tool, but for what?
Before I get to that, I want to talk about a goal from when I started lifting weights in June. An initial and realistic goal would be to lift my own weight within one year of taking up the training.
I knew that our bathroom scale weighed light but from the standpoint of monitoring weight this doesn't really matter. It may be systematically light but is consistent and so fine for keeping track of gain or loss, as the case might be. My wife has scientific training and was not happy with that answer, she wants to know what she really weighs. That plus my new need to know what I really weigh, led to this:
The hook on the end of the tool was to connect a rod in the tower to the mechanism in the platform. The screwdriver like slot is to adjust the zero and the hex hole was for bolting on the height measuring rod and the wheels.
