45 adapter doesn't fit over Mike New Spindle?

[jamington2004]

Went to stick on a 45 with a big hole in the middle..... and the 1210 adapter doesn't fit over the Mike New spindle!!

Is this normal? Does he do one that fits?

Thanks :)

Same here :scratch: ....... But a plastic one fits.

I would presume so as the spindle is a different design when compared to the stock 1210 variety :)

Hello all,
The one thing that's constant about turntables/record players, from SP10 Mk3s to Dansettes, is the diameter of the bit that sticks out of the platter - 9/32" or 7.18mm. Otherwise we couldn't get records on them.

Now anything has a tolerance, and many manufacturers, particularly of specialist bearings, will use the top limit of size for bearing performance purposes, but that is all it is, a tolerance mismatch.

The plastic adapters most times will stretch enough to fit. A little rub with a rolled-up piece of emery or wet'n'dry paper will take care of the alloy ones.

That's strange, Jamie - my adaptor fits over the MN spindle. I know because I've recently been recording some ex-juke box 7" singles to tape :)

Something weird is going on there...

Over years of production there is likely to be some small differences in the size of the stock 45 adaptor. They won't all be from the same production run after all.

Mine fits as well.

Possible, my Techie was born in 2000. :stalks:

[jamington2004]

Guess mine and Johan's must be bigger than yours!!

Spindles that is!!!

Guess i'll get to work loosening the hole on the adapter so my extra girth can squeeze in!

Sorry... Thats it now i promise.....

[prestonchipfryer]

Mine doesn't fit. Some of my LPs' spindle holes are quite a tight fit and I think this is intentional. Snug fit on the spindle is, I would think, desirable.

It could be that the Technics' 45 rpm adapters vary in spindle hole diameter.

I hope you are still talking about the Technics........ :D

NO NO NO!!!!!!!

Have you EVER used a 1970's Thorens? The spindle is always slightly oversized, so that many records have to be carefully eased into position. All the other turntables I've ever used and sold, have ever-so-slightly smaller diameter spindles in comparison to Thorens. The Rega plastic spindle is somewhere in between, which is why I recommend a gentle tap into place of a freshly placed record on a Rega.

The above makes me suggest to leave the MN spindle WELL alone, and buy a vintage Thorens 45 adaptor - the one fitted to all their decks in times past. You should have no issues at all then :)

[Johan]

Can you have the same problems with platters ?? Such as the ETP or Funk Firm ??

[phonomac]

Hello DSJR
YES YES YES !!!

For a long time, my main table was a 1974 TD160, and it has a tight spindle on records, but it's made to the extreme top end of a tolerance range regarding fits between nominal parts. It's nominal size is still 9/32". And if you have a (relatively) inelastic material like aluminium for your 45rpm adapter, and it is 0.0005" smaller in bore diameter than the spindle, then it won't fit until you've been holding it long enough in your hands trying to install it that it warms up, and hey presto it fits.

In the practical, real world of mass produced objects there is no such thing as an absolute fixed dimension. It must be associated with a tolerance.

Thanks ill try and find one :)

Just tried mine and it doesn't fit!

I only have a few 45's though and all of them have a normal centre hole,so not a major issue for me!

[OneyedK]

Mine fits... :champagne:

How are you finding your Jelco? Your set up is almost the same as mine - and I am looking for a new arm :)

Hi Folks,
Concerning the spindle diameter and tight fit. I specify the spindle to be be nominally 17.170mm Now this is about 2thou over the RCA stated size.
When I started designing the Bearings some three years ago, I sugested that I would make the spindle just a bit larger in order to reduce the effects of the oversize holes in many records; everyone agreed that this was a good idea.
If your centre adapter or weight it tight, then open up the hole with a small round file.
These components are not machined with the tollerances that I specify, and some may turn out to be tight (or loose)!
