<HTML>Anthony,
They sell 100T *hand* chain hoists. Perhaps you should contact these companies and tell them they are making exaggerated claims!
Metric against Imperial. Makes no differance, its still within the capacity of the machines in question.
What on earth makes you think that Ed would only have had cast iron available? Sorry Anthony, but you dont seem to know much about engineering history if you think that the 1930's were in such a primitive state.
So Ed weighed 100 pounds, so what? This is about gearing, not brute strength. I know a few smallish boxers who would scoff at your attempt to relate size to strength btw.
You seem hung up on the 4:1 ration in the photograph (which, lets not forget, shows him actually lifting a block). We have one photo, not an inventory of everything he used.
I've upheld my end of this particular show and tell and now its time you did the same. I want a full specification, diagrams and photographic proof of the device at work. Anything else is just empty rhetoric, sorry but thats where I find myself on this particular issue.
Regards,
Derek</HTML>
