Gooey Cube

THE MOST NON-SKID, STICKY, SEMI-RIGID SURFACE I'VE FOUND IN MY 27 YEARS OF PEN REPAIR. These are great for at least two things done by practitioners of our avocation:

1) Turning-out Parker jewels (clip screws).  REMOVING PARKER JEWELS FROM THE TOP OF CAPS 
To get a jewel (Parker called them "clip screws") off, try any and/or all of the following: 
First, put the cap with the stuck jewel / clip screw into an ultrasonic cleaner and run it several 
times for 3 minutes with several minutes of cool-down time between runs; you may want to then 
let it soak overnight in the ultrasonic cleaner with a detergent solution in there without it running 
and then in the morning hit it with a few more 3 minute runs. I have an ultrasonic cleaner that 
runs for 3 minutes each time the start button is pressed and then it shuts off. So I hit the button 
several times in the course of a day when I walk by. 
Secondly, after you take it out of the ultrasonic cleaner, wave and rotate it around in a 150 degree 
Fahrenheit airflow ( DON'T USE A HEAT GUN) for 1/2 minute or so; you don't want to get it 
too hot or the threaded stem of the jewel/clip screw can break off in the next steps while you are 
trying to turn it out. 
Now, before it cools off, try some of these tricks: ----- Note ----- Parker tool #8057, if you're lucky enough to have one (Pentooling sells them), fits 
up and inside the inner cap and gives you a good, non-slipping grip on the body of the cap and 
has a big handle which you can use to bear down on the jewel / clip screw.  
Idea 1, shown to me by a grouchy old timer at the Chicago Pen Show decades ago: take a 
short piece of tape, almost any kind, about 1 1/2" long. Make a cylinder out of it so that the 
sticky side is out and then fold it flat. Stick it to the tip of your opposable thumb and press and 
try to turn the jewel with that. 
Idea 2, that I use a lot: get a piece of latex or sticky rubber and put it on a sort of firm 
surface. Something else on the market called “Gooey Cubes” works really well also, without a 
top layer of latex or rubber.  Experiment with this; some surfaces work better than others, but if 
the second surface is sticky too, that will help. Press the jewel into the soft, sticky rubber while 
trying to turn it.  Be forewarned: Gooey cubes, at first glance, don’t look like anything that would 
work.  They are not wet or necessarily that soft.  In fact, they appear to be dry.  But they are the 
best thing I’ve found for this job in almost 3 decades of pen repair. 
Idea 3, layer the materials used in the above two steps together. 
Idea 4 (and this is the most helpful), start over with the ultrasonic cleaner followed by 
heat and the rest of the steps. SOMETIMES IT TAKES ME A WEEK OR MORE OF 
REPEATING THE ABOVE STEPS, but I can usually get that sucker off by going through the 
sequence over and over. 
Any good source of supplies for working on pens can provide most of the above tools.

2) Un-clogging buffer sticks and other abrasive tools such as tiny sanding drums. You can do this over and over. The use of Gooey Cubes can increase the useful life of abrasives by as much as 5 times.
