Richardkrebs: I have aquired the necessary equipment and will be constructing my TT in my own shop. Your comment regarding constructing the arm pillar and pod ( assumming we are talking about the same thing) as one, doesn't seem necessary to me and in fact seems a step backward, IMO. I choose to go with Bruce's original design as much as possible, bowing to his expertise on design and knowledge. I will be using the 'granite surface plate' to have an accurate 'plane' as a reference for the build and final placement in my system, not for actual use in my system. The arm's final trueness will have at least one separate adjustment, the 3 point ET arrangement. My focus is to make each of the four portions 'true' in every step of the build process, all the while knowing I have multiple other options available in my personal system/set-up that I can count on to get me to the 'true' point. My personal goal is perfection, then knowing that isn't always acheivable, I can rely on the ET adjustment/ arrangement.
I have to say that as regards to using acrylic as a platform for the vinyl record and in my own system, IE: the armboard, I do agree with Fremer that this isn't the best material for great transient response, tight, controlled musical bass @ realistic sound that I crave. Of coarse this is solely from my own system experience and personal preference.
