Dr Rob is on a distinguished road
..."he's going to put together a contraption so that i can lock down a penn 80 international, set the drags to 50#, tie off the line to a digital scale, find some way to measure the temperature of the drag disc, and give me continuous readings of handle rpm, pounds of drag pressure and temperature all as a function of time..."

That's pretty much what I have already. It's a pretty good rig, but I'm finding it has some shortcomings. I'll have to make another one with a few improvements. It really takes a long time to go through a number of materials in an orderly fashion.



Captdeej, about using amperage draw... that's pretty clever; hadn't thought of that. On the other hand, it is also a good thing to aspire to maintain a real-world application scenario as far as possible. I mean, there are dedicated tribometers available, but they remove the components and materials from their environment. Also bear in mind that this talk of the various drag materials is only part of the equation of a functioning drag. The sum total of all components is what does it.
