Interesting, but I have to say that does sound a bit problematic in several ways. For one, I’m guessing you meant to say “one mm”, or even “one quarter of an inch”, but not “one inch”. One inch is quite a soup bowl! For another, anti-skating force compensation must pull the arm toward the outside, because skating forces pull it inward toward the spindle. So you’d need an inverted bowl, higher in the center, to use gravity for anti-skating.

Hm, perhaps we imagine the process differently. In my view the anti-skating force compensation must pull the arm not toward the outside but rather toward to inside. The skating forces pull arm not inward toward the spindle but toward to peripheral.

Regarding the tight intimacy between LP and platter. This is complicated subject. In some cases the tight intimacy LP and platter is great in some not. I have no idea what the rule is. I have seen the TT with LP were literally floating in air on 3 contact points and I have seen some crazy platter binding solutions. It is very hard to make a generalization between different TTs considering that they all produce different results and they never sit in the same room, setup by the same person. My general feeling, based on extrapolation rather than empirical practice, advise me that as soon LP and platter are bound and develop intimacy then many uncontrolled conditions begin impact sound: like own sound of platter. If it happens that your platter for instance “sound good” then it might be not a bad thing but I feel that to cancel out as much as possible variables is more stable way to go. It is like some people build SETs with 4-8uF last capacitor in B+. Then they go over the pain to choose the transformer, chokes, rectifier tubes and zillion other elements to make the output channel to sound good. I prefer to rise the volume of the last cap with would diminish or cancel the “sounds” of the preceding PS elements and “use” only sound of the output tube with good but “default” PS. I feel the very same with LP and platter. I would like do not know about the platter sound this why I have think but hard robber mat on the top of my platter. I for sure do not insist that this is the only way to do but this approach make me to be at peace with my “what if” frustrations.
