Conway Stewart 15 Cap Band Loose.
Posted 05 October 2019 - 01:15
My question relates to the 15s cap band being slightly loose, not coming off but rotating askew in its groove. What adhesive is safe to use with this material so I can firm the band and not affect the cap material ?. As an aside, all levers are stiff so the sacs have petrified. I am unsure of sac sizes, I think the 15 takes a No 16 sac. The Dinkies I believe are No 15, am I on the right track? . All advice gratefully appreciated. Cheers, Cris.

Hello from a fellow Antipodean and Conway Stewart enthusiast.
The first question must be, do you want the pens for a collection, or as pens with which to write?
If the former, the advice is to leave them alone, all I would do is remove the old sacs (to prevent discolouration of the plastics due to the gases produced by the deteriorating sacs).
If you want to "restore" them (i.e. use them for writing) then the following applies:
Don't worry about the rotating cap band. This is a result of shrinkage of the plastic and is very hard to remedy. Some 15s and Dinkies are made of casein, and any water-based adhesive (e.g. PVA) may affect this material. Introducing a more permanent substance such as cyanoacrylate may be effective but will potentially affect the value, as it's an irreversible action. Your choice.
When it comes to sac sizes, I use a flexible approach. Many of the sacs I remove from vintage pens are quite large, but my approach is to try various sizes, talced, in the barrel, and use the largest that will easily (and I mean easily!) slide into the barrel. I then check that this size sac will fit over the nipple in a way that is tight but not too tight. It should require a slight stretch, but not so much that it will tend to slide off the nipple once lubricated with shellac.
Remember that the smaller the sac, the less likely it is that the heat of your hand will be transferred to the contents and cause flow issues. Against that, you have to balance the amount of ink you want to be able to fill.
