Securing Parker Clip Screws And Jewels....

[DavidCampen]

The absolute best way to remove and install most jewels in Parker Vacumatics and 51's is actually very simple. Get a hot glue gun and put a generous drop on it. After it hardens, you can turn the glue blob and the jewel comes out easily. Peel off when done. I've done this tons of times with no ill effects to jewels. Anything stubborn just requires a 5 minute soak in water before turning. To date, I've never had it not work. Hope this helps someone, since it beats all other methods I've tried by a long shot.

I am thinking of trying using sealing wax to hold a Parker 75 tassie so that I can unscrew it. I have gotten some off using a rubber band etc. for gripping but some tassies are more resistant to unscrewing.

Use a rosin based sealant.

Would there be anything wrong with using a good, non-abrasive eraser to unscrew the jewel?

If its sticky enough, it might work.

I am not sure if you still read the FPN but I wanted to thank you for this most excellent tip.

 

I have managed to remove three recalcitrant clip screw jewels from three English Duofolds very easily using your technique. Previously, I had no success on these pens with the conventional methods.

I agree with Hari. Thank you monkeydonot for this clever hack!

 

After days of trying, I finally got the jewel out thanks to the heat gun trick. See below:

Thanks!

 One thing that nobody mentions but I find useful is to support the cap from the inside. This helps alleviate friction against the cap when pushing down on the tassie.

I thought my first post would be a question, but this is so amazing that I just had to thank monkeydonot for the idea. Opened five jewels with no effort at all today, after having a lot of problems with two of them using heat and rubber. Thank you for this time saver!

A rubber ball with a tacky suface, washed clean, conforms to the caseback of a watch when downward pressure is applied, and can unscrew it. The watch tool company Bergeon actually makes balls for this express purpose, the Bergeon "8000" series. I tried using an 8008 on a jewel and it works. You do have to squeeze it a little harder than when using on watches though. That makes the ball take an vertically elliptic shape and reduces the contact area & deformation from pressure, to ensure that it only grips the jewel and not the clip ring too.

 

I've used hot glue in the past and it's just fine, but the high temperatures involved do scare me a little.
