Securing Parker Clip Screws And Jewels....


Ron Z

Recommended Posts

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.

All these moments will be lost in time, like tears in rain.

Use a rosin based sealant.

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

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:

 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.40592032_Capremoval.thumb.jpg.2280e14c6eb9e9d3d90f3656ca565834.jpg

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.

      I have the Sailor Naginata and some fancy blade nibs coming after 2022 by a number of new workshop from China.  With all my respect, IMHO, they are all (bleep) in doing chinese characters.  Go use a bush, or at least a bush pen.

      It is the reason why I'm so keen on the idea of a personal library — of pens, nibs, inks, paper products, etc. — and spent so much money, as well as time and effort, to “build” it for myself (because I can't simply remember everything, especially as I'm getting older fast) and my wife, so that we can “know”; and, instead of just disposing of what displeased us, or even just not good enough to be “given the time of day” against competition from >500 other pens and >500 other inks for our at

      Agreed.  And I think it’s good to be aware of this early on and think about at the point of buying rather than rationalizing a purchase..

      Alas, one cannot know “good” without some idea of “bad” against which to contrast; and, as one of my former bosses (back when I was in my twenties) used to say, “on the scale of good to bad…”, it's a spectrum, not a dichotomy. Whereas subjectively acceptable (or tolerable) and unacceptable may well be a dichotomy to someone, and finding whether the threshold or cusp between them lies takes experiencing many degrees of less-than-ideal, especially if the decision is somehow influenced by factors o

      I got my first real fountain pen on my 60th birthday and many hundreds of pens later I’ve often thought of what I should’ve known in the beginning. I have many pens, the majority of which have some objectionable feature. If they are too delicate, or can’t be posted, or they are too precious to face losing , still they are users, but only in very limited environments..  I have a big disliking for pens that have the cap jump into the air and fly off. I object to Pens that dry out, or leave blobs o
