| Tables That Feature Bearing Friction In general we shoul decide, whether the main subject is how to design a turntable as a commercial product, or how to design a turntable which tries to reach the limits of playback possibilities.I must admit that it is rather depressing for me to r... | |
| Tables That Feature Bearing Friction Dear Kirkus, the "controlled slippage" is tricky to set-up, but if used with the "right" (= close to zero elasticity) thread it is very durable and does not request to be re-adjusted.The drive-system is - as always - a matter of quality in the sel... | |
| Tables That Feature Bearing Friction Dear Lewm, a no force belt/thread/string driven bearing is done this way: picture the motor left of the platter. On the right side - same distance as the motor to the bearing - is a 2nd spindle (or easier: motor without active force) which mirrors... | |
| Tables That Feature Bearing Friction Dear Mrjstark, dear Teres, if there is more then theory, then we are either in mysticque or religious grounds.Different belts having different (negative and positive) effects on the bearing an dteh rotating mass system and on the transmission of v... | |
| Tables That Feature Bearing Friction Dear Teres, dear Raul, I guess we all agree in most aspects regarding the main topics / issues of designing a turntable.I just have a very different threshold for "compromise". However I would like to answer Teres's 4 points first and in order.I w... | |
| Tables That Feature Bearing Friction In fact Micro Seiki 's engineers were the very first to realisze the potential (in turntable design...) of high inertia coupled with thread drive resulting in superior extremely constant speed. Low grip, slip coupling and let the huge mass in rota... | |
| Tables That Feature Bearing Friction As for the Micro Seiki original belt / strings. The Micro Seiki RX-5000 came first with a fairly strong and wide rubber belt of very high quality first. However they did recommend too - right from the start - using an aramide string ( made out of ... | |
| Tables That Feature Bearing Friction I went through Mark Kelly's extensive teachings. Good research and explanations, but he is not focussing upon the center point.Some people will hate me for this, but I want to postulate a short and clear statement ( and I ask everybody to give it ... | |
| Tables That Feature Bearing Friction Dear Kirkus, I know that these were not your motivations - I just wanted to set some points clear as the turntable sure looks like a "mammoth" in the picture and thus the above mentioned suspect might easily arise. But - thank you.As for the strin... | |
| Tables That Feature Bearing Friction Dear Kirkus, yes, I have put some money in that project back then, but I got paid back and in the end I did not loose any money on that project. As I usually do like to link philosophy with my audio discurses, I must however admit - not today . I ... | |
| Tables That Feature Bearing Friction Dear Raul, right now I am in the process of building the successor of the turntable Syntax has pictured. This project will be finished in autumn this year. I will include some thoughts and technical features I either could not include back in the ... | |
| Tables That Feature Bearing Friction Dear Halcro, thank you very much. To speak in the words of an era in architecture we both do favour: .....form follows function..... ;-)) | |
| Tables That Feature Bearing Friction Dear Lewm, we can not achieve perfection - we can only try. The long string is no compromise at all. Yes, the string has no stretch at all (a special kevlar derivate). The point is not control of the platter rotation. The point was to prevent the ... | |
| Tables That Feature Bearing Friction Ghosts of the past.........that particular unit is from 1993. The base plates are corian on dural with polyurethane layer.80% of the technical periphery is inside the integrated "stands" of turntable and motor unit (including active air suspension... | |
| Tables That Feature Bearing Friction Dear Raul, yes - a different room is the one and only way to isolate any turntable effective from SPL radiated by the speakers. No doubt. However - this has nothing to do with the turntable design itself. It is a matter of the enviroment/position.... |
