Vintage DD turntables. Are we living dangerously?

regarding cantilevered armboards it seems to me we should look deeper into aspects like how long is the cantilever, which forces are put on, which are the mass ratios and which is the source of the resulting energy of the scanning process? If we do so we clearly see why the cantilever beam plays no important role!

Lewm, MS boards are flimsy??? When have you been standing last time on an original Micro Seiki armboard? Or do have double my weight? :-)

Fleib, Dover`s rules do apply to all TTs - regardless of drive mechanism.

Despite the convincing conclusion that platter and tonearm bearing should ideally not interact in relative movements I have experienced that it depends on the way of execution, e.g. in the Continuum or with my Toyo stand.

when the Victor arrives and has been repaired I will look into it again. Thanks all having supported me here so far and exchanged ideas - very helpful indeed !!!

Tuchan,
In this case Halcro's table meets Dover's criteria for a closed loop. The loop is closed by the mounting base rather than a plinth or chassis.
Regards,

Lew, did you ever manage to get hold of a Reso-Mat?

Moonglum, No, I have not tried it, yet.
Halcro et al, I only re-stated the case for a rigid connection between tonearm and bearing for the benefit of anyone who is reading this thread for the first time. Such an individual (Thuchan in this case) ought to hear both sides of the question before deciding which direction to choose. Like Henry, I am past trying to convince anyone else who has already made up his mind. But Henry, with all due affection and respect, your analysis of the L07D is ludicrous, certainly compared to the risk for drift of alignment of a fully outboard arm pod. The L07D is a system, using several different metals (stainless steel, alu, brass) with different temperature coefficients of expansion, closely coupled with substantial fasteners and massive. The temperature of a typical listening room varies by a couple of degrees during the course of time. Of course, if you leave your tt in the freezer on off days or cryo-treat the entire unit, you may want to do a re-alignment.

Lew...and this assumes that the feet of an outboard arm pod are even non-flexible and the mounting surface is stable - both dimensionally and mechanically in phase(!) ;^)
