Question Turntable spindle sizes

I'm looking for a list of turntables manufactured with a spindle diameter of .288" (7.2 mm). Yes, I know it's not exactly a DIY question but then again if you are in the process of designing your own table the spindle diameter is another one of those decisions you will be making.

Hi, I thought that the standard had been 0.283" +- 0.001" for *ever*

What would 0.288 work with? I have LPs that are a tight fit on a standard spindle.

regards, jeff

I sure can't disagree with you, it is a mystery to me as well. I bought an overhang adjustment tool some time back and had to pick my spindle size (I picked the small size). That's when I learned the AR XA spindle is .288 inch. I now have an AR EB101 and it is .282 inch (I don't believe it's worn down that much from vinyl sliding over it). Some or possibly all Rek-O-Kut tables have .288" spindles and there are others.

The reason I am seeking this information is because I machine and sell novelty 45-RPM spindle adapters and some customers simply can't get the .282 adapter (actually machined to the high side of .283 to compensate for the + .001 tolerance) to fit. Thus it would be nice to have that information.

In the process of making the adapters I have discovered there is considerable variation in the hole size of 45's just from wear and do not want to add even more runout from the spindle hole. People have rightly accused me of being picky about such things.

Default The LP standards...

Jeff,

have a look here
a complete table.

.286"=7.2644 mm, the variance allows down to below 7.24 mm, so I'm thinking that any spindle of 7.24 mm is good

Jeff email me regarding platter.

I do recal there are at least 2 standards, and probably 3, but can'r remember what the values are. Some LP cleaning devices here have two diameter settings, but the designer said one of the diameter serring can be used on LPs of two different sizes, which I presume is the size difference due to English and Metric standards.

FWIW, my Rek-O-Kut Rondine2, which is a little corroded, is 0.2822". My Thorens 295MkIII is 0.2814. I still get a record every now and then that's tight on the Thorens, but not many.

Did a steel spindle precisely with 0.283" and have found it most suitable with my Rega. Random LP may be a wee bit tight fit but its still ok.
Rega plastic original somewhat varies from 0.280" to 0.282, random measurement from some throughout the ages.
