Designed new stereo stand, horizontals are 2 layers of ¾" quarter sawed red oak plywood faced with ¼" solid red oak.
Verticals are 1¾" turned red oak with hole through center to accommodate fasteners, see attachment detail in top right.
Chosen vertical diameter allows a sleeve of several different types of thin wall metal to be slid over as a cover.
Aluminum, stainless, brass, nickel, chrome are some of the options readily available. I'm leaning towards stainless steel.
Here's my drawing of new stereo stand and sheet layout:
