Removing inner cap from Sheaffer Tuckaway


ngc2632

Recommended Posts

I have a Sheaffer Tuckaway with a loose clip, so I have a need to remove the inner cap. I've read two Sheaffer service manuals and there is no mention of how to disassemble their caps. Are the inner caps pullable, or are they glued in? Is there anything I should know about these caps before I attempt to pull it?

Tough problem. Sometimes, the cap can be removed. Basically, the cap consists of a "shell" (with the clip) that is over the metal cap (which is what you are referring to as the inner cap. Thus, the whole construct is basically a plastic or metal veneer over the cap which is a closed section of a tapered cylinder with the threads.

 

I have had some luck pulling off the outer cap shell with VERY gentle heat, using an old barrel as the cap puller (since the diameter is greater than any of my cap pullers). However, the plastic deforms very easily and, if it is celluloid, is likely to shrink. I've had the most luck with metal caps that can withstand more heat.

 

Hope that helps.

I was hoping that wasn't the case. The inner cap looks too thin not to be fixed to the shell with adhesive. My Tucky is all striated Carmine... maybe the safest approach is to lift up the clip and apply some adhesive to where the clip protrudes through the shell?

If I recall, the Tucky does not have the spring clip of the larger pens...just folded tabs. I will try to xray a Tucky today to be sure. Perhaps that will help with the decision.

Here's the xray showing that the Tucky does indeed have Sheaffer's excellent spring mechanism. If your clip is loose, it is probably because the little spring clip has broken. This can be easily fabricated and replaced....IF you can remove the outer shell, which can also be seen in the xray. It is glued with adhesive. The issue, as I mentioned, is the sensitivity of the celluloid to heat. Perhaps Ron Zorn or Richard Binder have some experience here. If removed the outer shell on later Snorks, but that is less heat sensitive plastic.

That is a wonderful idea, Antonio. I use just about any source of cheap, springy metal (high modulus of elasticity, minimal ductility) such a a battery clip from one of my childrens' old toys.

Wow! This is a real solution for non-destructive diagnostics.

I guess it was technical not medical x-ray?

I never thought about this.

 

I could probably take my various pens to a customer and have him x-ray them for me. (physical therapy clinic)

      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
