Securing a Presto 45 adapter?

[piaptk]

My 45 adapter used to stay in place just because it was tight, but over a year of use it has loosened up to the point that it rides up and starts dragging on the bottom of the platter and slicing up my puck. How do you get this thing to stay down? Do I have to drill a hole in the motor shaft and screw it in? what kind of screw should I use? Does my drill have to make threads in the shaft? I have no experience with metal work.

My 6n already had threads and a screw tapped into the shaft. I was under the assumption that this wasn't a mod by the previous owner but perhaps it was. Either way mine stays put. Let me know if a pic would help at all.

Hi,

I have a picture of one that I grabbed off of an ebay auction some time ago. This unit had a set screw near the bottom. If this is the case with your adaptor, maybe its loose.

That was probably standard on later era 6ns, which were produced after the 45 was introduced, but mine predates 45s. Got this email back from Kim Gutzke:
first - clean shaft and inner sleeve using lacquer thnner or gas or solvent
 
make sure no oils have gotten onto shaft
 
try that
 
if no good - try one of these
 
add a real thin metal shim - like a piece of aluminum foil - whatever
 
or add a dab of elmers white glue - which should allow easy removal
 
or try some Scotch brand restickable adhesive glue stick (purcased at officemax - etc.) - see attachment
 
the idea is to add just enough to keep brass sleeve in place - but not too much where it makes it difficult to remove
 
another thing that might work -- spray or simply dab shaft with light coating of clear lacquer.  That will make it stick when dry -- and when removing add heat from blower or something to melt the lacquer
