    Oyaide is using holes, so if you copy them, you should get similar results, good or bad. I'd like to think they considered all that stuff?

    And yes, of the metal options offered i'd say you chose wisely. If you want to dress it up, how about machine turning? You know, you take a small disc with sandpaper or polishing grit and give it a half turn, letting them overlap a bit. Leaving swirls all over it.

    And if you really wanted to pitch the disc, so it is higher at the outside edge than the center, it only needs to be a millimeter or two difference? The proper way would be to actually cut the disc that way, flat on the bottom, dished on the top. To maintain contact under the disc. I'm just thinking out loud here, for the sake of conversation. It really is just great like it is! Do you use a record weight? Or clamp?

    No clamp or weight unfortunately. Now might be time to invest in one I guess.

    Are cheap clamps are as effective as expensive ones? Frankly, I'm a bit poverty-bound and have always struggled to justify shelling out the cash for a one of the expensive ones. Perhaps a $20 ebay one is worth a try.

    Russell, those are all great thoughts. For now I like the look as is, from a minimalist point of view. machining the disc for pitch would most likely give an improvement, but would push it out of my anemic budget.

    Really it's just for the sake of cool-ness and the hope of improving speed stability with mass. Does that work with DD, or only belt drive?

    I don't see any evidence that the cost of a record clamp or weight had anything to do with its effectiveness. But I know they work! I had a Monster Cable brand clamp for many years, gave it to my son in law. I paid $35 for it back in '87. Bass was much tighter and deeper using the clamp.

    And I don't see why rotating mass can't help a DD the same as belt or anything else. The theory remains the same. IMHO of course.

    My only thought is that perhaps without the belt to smooth over the differences between the belt and flywheel platter, a DD may not benefit from it like a belt drive. Conversely, the powerful motor would be fighting against the platter at any moments that they're spinning at different speeds.

    Really that's just a vague idea, rather than anything with no science behind it. Presumably technics had some idea what they were doing when designing the sp10 nmk3's 10kg platter. My platter now weighs the same as a mk1/mk2 sp10... but with 1/4 of the starting torque

    So perhaps the DD will be slower coming up to speed? But once it comes to full speed, gyroscopy will put the extra weight to use in steadying the overall speed. Newtons law of motion, the more mass the more it wants to keep moving and not change speed.

    Unless it's just really too heavy, and it can't get it up to speed? But I doubt that will be the case. And you'd know real quick if it didn't.

    A well designed DD will not be noticeably affected at start up. My SP10 has no problems with a tenuto mat (very heavy) plus750g puck. Depends on the turntable.

    Im not convinced SS is the way to go with this as it rings , just like the std platter that ring like a bell
    Best way is somthing inert or put some strips of sound deadening under your original platter , SS will have resonance

    Just my opinion ( But who an I )

    That may all be true but I would have thought that the mass of the platter with original rubber mat would have been calculated to work optimally with the motor. Also, while increased mass may improve rotational inertia, surely this would also make it harder for the motor to correct any changes in velocity (speed)?

    Pretty happy with the platter. I've still got to give the platter a good polish. It weighs 2.7kg and has no trouble getting it spinning. I've left the brake at the current setting and it only slows it down slightly.

    It lacks the vancy holes of the oyaide, but Oyaide claims that those are to reduce resonance... which I really don't believe is a concern with 2.7kg of solid steel.
    It also lacks the gentle dishing which makes the Oyaide with its weight so good at flattening a record.

    And the tenuto which is excellent both in sound and flattening vinyl.
