Should have written "I know how to calculate the temperature elevation", for my first sentence above. Q is in joules, a unit of energy. Thus Q. would be equal to the kinetic energy generated by friction between stylus and groove, a function also of velocity, because neither the stylus tip nor the groove can dissipate energy any other way, except as heat. (But that's the rub; some energy is probably dissipated in "stretching" the groove walls, too.) Being in biology has nothing to do with this; I never studied physics except in college, so I hope the above is correct.
Do wooden arms warp
I hate to sound stupid or pedantic, but I have historically done a lot of woodwork - turning/routering/bedmaking. The single biggest problem is locating wood that does not warp.
Wood cut and left to settle over 50 years continue to warp, likewise, even very old wood warps as well. In my experience when a piece is smaller/thinner it is more pronounced unless there is some lamination (not always a cure). I am yet to come across or find a treatment which stops warping. It would be nice if a manufacturer of such an arm chimes in on this thread, because arms such as: Durand, Shroder, Reed etc all have wood arms/options and they really are the most expensive arms out there.
