Removing inner cap from Sheaffer Tuckaway

[ngc2632]

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.

Miko,

 

Wow. That's quite a photo!. Now I know what I'm up against.

Hi,

 

Just a question : from what material do you make the spring from? Anything that can be easily scrounged or obtained?

Besides, here's my very own patented design inner cap puller :

 

 

All the best,

Antonio

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)
