Krazy Glue, Or Gorilla Glue?

[JefferyS]

Anyone who frequents the Parker forum knows that there are issues with Parker medallions falling off the cap. Through the kindness of a FPN member in France, I have a replacement medallion to glue to my Parker Duofold Centennial. I have removed the old glue from the cap using a dental tool. I was amazed that it pretty much came off in a contiguous sheet, suggesting that the factory glue really didn't bond well with original medallion or the plastic cap.

 

What should I use to glue the new medallion to the cap? I have Krazy Glue, Gorilla Glue, and some epoxy glue (somewhere), the type that comes in two tubes.

 

Any suggestions? Krazy Glue is crazy stuff. Remember, I'm the guy who Krazy-glued a part from my regulator clock to my lip. Gorilla glue is supposed to be good, but it does swell up after application.

I would say a thick cut of shellac. That will stick to mostly anything, and reversible.

I do have some shellac from Richard Binder that I use to glue sacs. I'm a bit paranoid about its permanence.

Gorilla glue is a definite no. It expands into a foamy substance to fill gaps. Then it turns hard as a rock. It would seem to me it would make a mess of things. Good for wood (what I have used it for), not pens.

Definitely not the standard Gorilla glue, There is a Cyanoacrylate (super glue) in the Gorilla glue brand that would be ok.

[JefferyS]

I'm glad that you mentioned cyanoacrylate. I looked it up and was reminded that it reacts with cotton by undergoing an exothermic reaction that can be dangerous. I was considering spreading the Krazy Glue with a cotton swab. Bad idea.

Shellac will last, just like urushi. The wonderful thing about shellac, is that it can be reworked at a later date. It will stick, no doubt, but it also has the benefit of being easy to remove and clean. If that pen ever needs to be reglued, you could easily remove the old shellac and reapply some new shellac. CA glue needs solvents that could melt your pen if you decide to remove the old CA.

Yep I have used it with a cotton towel while applying a pen finish and it would create a lot of heat and even smoke. At least it never caught fire :embarrassed_smile:

I don't think any pro would recommend any of the Super glue formulations for at least a few reasons;

 

-It tends to get everywhere you don't want it to on application.

 

-It will fail sooner or later with any exposure to moisture.

 

-When it does fail, the remnants are difficult to remove for any more proper subsequent repair.

 

The only time I think shellac would be recommended for a repair like this would be if there would be a future need to remove the medallion for a cap repair. I don't know for sure but I don't think this is the case with the modern Duofold. I would presume with the scarcity of the medallions, you want it to *STAY* where it ends up.

 

I believe when a true strong adhesive is needed the recommendation would be for a two part epoxy. Ron Zorn has recommended Devcon before though I think a lot of the pros use expensive, hard for the hobbiest to procure professional epoxies.

 

Devcon makes a 60 sec and 5 minute 2 part epoxy. I have both. I've never been confident enough in my get it in the perfect position the first time ability (see Super glue, above) to try my luck with the 60 second stuff. I have used the 5 minute for a few applications like this medallion. I haven't heard of them coming unglued and I don't think I will. The 5 minutes is plenty of time to get the items in the correct position but it still totally dries pretty quickly.

 

Tru-Value hardware stores carry Devcon epoxy.

Get a roll of Scotch Permanent Double sided Tape.

 

It is very thin and will bond to the surfaces that you wanting to attach.

 

This is available at any office supply store.

 

Another possible is go to a picture frame shop. They use a dry adhesive that can attached the end piece also.

I found my two-part epoxy, but it is "Ace Hardware" brand. It will probably be fine (obviously Ace Hardware doesn't have its own epoxy factory). I will never want to have this medallion removed. I wish it weren't there in the first place, but having it missing is just too ugly. Epoxy will also fill the hole in the middle of the cap. If the medallion had a post to fit into the hole, it would have never fallen off.

[professionaldilettante]

Two part expoxy will work, longer setting is best. but make sure the two mating surfaces are free of dust and oil. Wipe it off with an alcohol wipe or something.

As others have already said .. no Gorilla Glue! I had several bottles a while back and what no one wanted for free, I threw out! Never worked as claimed and was a pain in the ... well, it was a pain to use! If I'm gluing metal to metal or metal to concrete or concrete to concrete, I use Locktite for metal. For most things, I use "Weldbond", as it will bond most things to anything else. Is the best wood glue I've ever used and that included most "wood glues".

[JefferyS]

I'll probably do the epoxy.

Glue question here, but not for pens. Please forgive me for going a little off on a related question.

 

The knobs on my stove have these little metal caps on them. What glue would you recommend for these? Has to be able to withstand some heat. The knobs are black and the aluminum caps have a slit in them for the black indicator to fit through. Wouldn't want the glue to ooze out the top.

 

Appreciate any and all suggestions.

Can you use JB Weld?

I'd vote for a thin coat of shallac, try to stay off the very edge, then glue and clamp for a few hours..

 

Less . should be best in this situation.. Other glues as refereced above may be overkill.

Good Luck
