Direct drive vs belt vs rim vs idler arm

Sksos1,

I think we all know which one you will put at the top of that list!

Seriously, such a list would be surprising to a lot of people, and it would undoubtedly generate angst among many manufacturers, not to mention all the explanations from end users claiming the results are from someone with an axe to grind, or it was just some unlucky random sample. Whatever, the thread would probably become Flame City right away.

Wouldn't it be interesting if the only tables to pass the 'Timeline' test were all 30 years old?

Halcro,

Yep, but that won't happen. A lot of new ones pass, but the surprise is which ones.

Some old ones don't pass, however. I built a DIY turntable around eight years ago that started life as a Lenco. It runs a little less than 1/4 RPM too fast no matter what I do, so after a frustrating hour wasted I quit tinkering with it. I could never get the wheel placed accurately enough to correct the issue, as minor as it may be. It's dead on according to the KAB Speedstrobe, so I suppose it is close enough. Maybe I'll revisit it someday.

The real problem is with those turntables out there that do not keep a consistent speed. It is one thing to have an ever so slight speed issue that is evenly paced, but quite another when it varies, especially if it varies abruptly.

Mosin,

A lot of new ones pass, but the surprise is which ones.

This sounds like you could already produce a list for us? :-)

I have checked a few, but mostly I have checked motors that are commonly used. I was surprised.
