Michell clamp too tight for Spacedeck?

The Michell clamp is too tight. Anyway I sold it away.
Any recommendations for a clamp with the Mystic Mat on the Spacedeck?

Here are the measurements of these clamp's spindle holes:

Michell: 7.12mm
Acoustic Signature: 7.05mm
Basis Audio: 7.28mm

I recommend you take a look at the Basis clamp. Its overall diameter is about the same as the Michell clamp, but the spindle hole is wider. I'm not sure if the specs are the same for the new clamps since the one I have is about 2 years old.

You may want to contact Nottingham and ask for the spindle diameter of your turntable's platter.

I suggest you take a look at the Bren1 record clamp.
It's really an unthreaded weight. I am the manufacturer
and have sold to many Nottingham owners. Of course you may feel I'm bias so check out my feedback on Agon, Ebay and Amazon
