The prony brake test has been removed. The reason is on March 10, 2008 post.
The OU prony brake tests of the 7.5hp Baldor rotovertor are detailed in message #13755
"Actually those prony brake tests I cannot duplicate now, so I don't stand by them anymore... Can you take down the link to this wherever it is?
I think it was just bad math is all and also bearing problems too...look where I say the prony brake weishg so many ounces - over a pound weight to the prony brake - this is really dumb.....Petere didnt see that bad mistake...this is a mixup of grams and ounces (duh) What Peter says is not right as far as I know however in calculating HP with prony brake tests...you dont need to konw the circumference of the shaft on the brake itself as far as I know. All that matters is how many ft-lbs is being pressed downward by the 1 foot bar. This is a minor thing however."
