    Default Safest way to remove a Parker 51 Jewel ?

    Hi all

    A quick question I hope

    What's the safest way to remove a Parker 51 Jewel from it's brass screw when it has been fixed with Shellac

    Heat, solvent or something else.

    Thanks for any help with this.

    Paul

    Paul,

    As you delve into the fun of working on your own pens, you might consider this wonderful reference. (I am still using the 2nd edition!)

    Although I have the book, what I tend to do first is to find out if there are any You Tube videos showing me how to do the job with the hands-on view so to speak.

    I found this one for removing a Parker 51 jewel, but if your jewel is shellacked in then you probably need to warm it up in some way before attempting removal. Most repairers will use dry heat, say from a hairdryer, although some might use an Ultrasonic bath. I tend to favour the latter when it's safe, like it is on metal 51 caps.

    Then you will need a piece of rubber, or even better, sticky rubber type material, that you can probably buy from various repairers. That gives you the grip to get the jewel out when you know it's not glued in.

    Hi all

    Thanks for the replies

    I did try one of te sticky blocks sold for this job but only managed to unscrew the brass bush the jewel is screwed into, I then tried soaking it in Naphtha (Lighter fluid) again without any joy. Finally I tried dry heat, fortunately I have one of those adjustable heat jobies sold for SMD solder work and that finally did the trick at around 120deg.

    I have ordered some Naphtha to try again on another one, just in case lighter fluid has been fiddled with under EU rules and now not as good as it once was.


    Thanks

    Paul

    Why do you want to separate the jewel and bushing?

    Ok I'll bite,

    Its to either be able to 're tighten the Bush which holds the clip in place or to completely strip a cap for de dinging etc.

    Well, if the bushing came out with the jewel in it, you don't need to take the jewel out of the bushing in order to work on the cap shell. And tightening the bushing can be accomplished by (drum roll, please) turning the inner cap.

    What does the verb "bright" mean? I can't find it in a dictionary.

    There are good reasons for wanting to separate a jewel from a bushing.

    Just found the ideal tool for removing the jewel for whatever reason you want to remove it

    Just the right amount of softness and tackiness to do the job. Just tried it on ten jewels and they unscrewed first go with all of them.

    Hello,

    I have never ventured here on this platform before.


    Read with interest all the comments.

    Thought it was odd that no one mentioned using the arrow clip to loosen the jewel.

    As for Dycem - it is impressive, if you can release 10 jewels using it without pulling the jewel from its thead sat in the brass screw you are very lucky.

    Hello Paul,

    I would 10 lottery tickets, they will all win, you clearly have the ' midas ' touch.


    Please can you tell me of the 10 you that removed how many did you just remove just the jewel.

    Of the rest, have you ever separated a jewel from the screw once it was removed.

    Any photography, help with understanding your technique would be greatly appreciated.

    Many thanks

    nb I am quessing you know someone who lives not far from a pub called the White Hart

    Hi

    It was about 50/50

    Of these the came out still in the brass bushing, a combination of soaking in Naphtha and gentle application of dry heat separated the rest.

    Technique is quite simple, put the black puck from the link above on the desk then push the top of the cap into the puck with firm pressure then just give a quick anticlockwise twist, as the puck is quite sticky it hold the Jewell still allowing either it the unscrew from the bush or unscrew it and the bush.

    For what it costs I can recommend it to anyone who needs to remove the Jewell for whatever reason, in my case I tend to buy some quite neglected pens so often need to strip the cap for removing dents.

    Paul
