For miscentered records, I use two different techniques: fi-l-ing and
fi-ll-ing.
One is making out the center hole to a larger size, grinding with a round
file of a suitable diameter that I keep near at hand for this purpose. I
file out the hole all around, but insisting towards the ill direction. The
results are good, and most of the times you don't need to grind out but a
few millimeters.
The other method is to sit a purposely made cardboard platter on the tt,
same thickness as the spindle size, so to get the spindle hidden, and
readjust the arm for the new height. Then I center the record on top. This
is a better method, as you don't hurt the record. But I don't like to have
no spindle at all, so I only use this in some sessions. Hidden spindle is
ideal for you can center the record freely. But I feel this unsafe; never
happened to me that a record flies off the TT, but when there's no spindle,
l cannot get rid of the sensation that it is going to happen at every
moment!
A cork platter should be ideal, for it's soft, light... I could not get
what I wanted, which was a neat cork platter of the desired thickness, so I
had to content myself with three platters made out of thick corrugated
cardboard, and piled one on top of the other, and a final 3 mm cork mat on
top. But it also works fine. Moreover, being three separated platters and
the cork mat, it allows resizing for different spindle heights, which I've
known!
