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.

Anything made of wood 'breaths', nature made it that way. So, yes your arm could warp. The type wood that it is made from would determine such, plus the temperature and the humidity in its environment. Best to dump it and get something made of metal or ceramic materials.
In addition to warp, I would expect the wood to change dimension slightly as humidity and temperature change. That's how it is with musical instruments...

You don't sound like either....
What you are saying is a simple fact of life and nature and you appear to have direct and close evidence of its immutability 😢
Unlike musical instruments....a tonearm is not appreciated for its tonal/dimensional changeability...but as is demonstrated by many design decisions made by audio manufacturers....science often plays second fiddle to 'sexiness'....😡
Honest, guys, this issue needs to be put to death. Whether "they" warp or not, and I don't doubt that wood tonearms are susceptible to warping, some wood tonearms are among the best I've ever heard, to include the Talea and the Reed. Vacuum tubes inevitably wear and change specs over time; do you wish to avoid vacuum tubes too, as a matter of principle? (Halcro, I know you prefer SS; that's not the point.) Cartridges wear out and change over time even while we are adoring them. Audio is an unstable hobby in general.

In the real world, modern tonearms are made by guys who do understand these properties of wood. Then the tonearms go to live in our air conditioned/heated living rooms; they don't sit outside in the rain. How much warpage over how much time is prohibitive? Does anyone really believe that a wood tonearm is warping at a rate that will ruin alignment and geometry within any period of time that makes this a real problem? Any evidence for that? Guys who don't like wood tonearms or who have some ax to grind regarding whatever metal tonearm he or she worships like to carp on this issue of "warpage". It's not a real world, real time issue. I don't really give a shit if my Reed has warped a tiny bit in the next 50 years. I have a wood Grace tonearm (which I just keep around for sentimental reasons) that looks by eye to be as straight and true as a piece of steel, after 30 or so years of living in a controlled humidity indoor environment. There are some theoretical advantages to a wooden arm wand in terms of dissipation of energy that can be said to be superior to metals, but I am not here to say that wood is superior to metal. I am just saying that wood is in the picture as an excellent material to use to build an arm wand, if the maker knows what he is doing. I have heard both carbon fiber and ceramic arm wands; they suck.
