    Default Doing my first pen re-sacking

    Couple of questions regard pen re sacking;

    Which type of sacks work the best latex or silicone?

    Do you measure the sack according to the barrel length, then cut off the excess?

    What is recommended for bringing back luster to a pen?

    What basic tools are needed to re-sack?

    Lastly any other advice?

    Thanks in advance.

    What kind of pen are you re-saccing? There's a standard list of sizes....and the kind of pen will help determine latex or silicone.

    Length can be trimmed as needed. It's the girth you worry about. Will it fit inside the barrel and can the J-bar activate easily? That kind of thing.

    Richard Binder's site is a good starting point.

    Do the Estie first, as they are the easiest pens to work on; be careful with the section on the Crusader, which can be a bit more difficult to remove. Both can be done with latex sacs - I reserve the silicone for pens where the celluloid colors will be darkened by the off-gassing of the latex sacs, and I doubt either pen has that issue.

    I started with an Esterbrook sac and it was very easy to do. I've only ever used latex sacs on Esties, a Swan and a few Sheaffer's. I watched several You Tube videos before I started, and it definitely gets easier after the first one.

    Be careful with the heat that you use to help you to free the barrel. Don't get it too hot.

    You will need to cut the sac to the correct length before you glue it on with shellac.

    Some will recommend a sac spreader for helping to get the sac on. I don't have one.

    Thanks for the reminder - I just got a Sheaffer Jade Senior needing a new sac, and that's one where I should probably go for silicone. (The colour is very green! The cap has some other issues but it is functional).

    I sometimes put the sac on without shellacking it first to make sure it all fits right (more often when it is one where a couple of different sac sizes seem like they could be right).

    I use my cross-locking tweezers to help put them on at times - they're closed when you do nothing and open when squeezed and can be used as sac spreaders, though they don't hold it open as roundly as some might.

    Thanks Deb, that's very helpful. Of special interest was the dusting of the sac with talc. I watched a TV show the other day where a very well respected restorer replaced a sac in a Wyvern and he did not show this step, although he mentions it in his book.

    I was watching the show with my OH as this pen was being restored and remember saying "don't forget the talc!" as he appeared to replace the sacced section without adding talc to the sac.

    Here is the post where I linked to the TV show in question.

    The latex sac is generally a better choice than silicone, with the exception of pens that tend to discolor when the latex sac decomposes. The jade celluloid Sheaffer is indeed a good candidate for silicone. When you do a silicone re-sac, be sure you have a silicone sac and not a PVC sac. David Nishimura's website and videos explain the difference.

    My experience is that the re-sac on the lever filler is one of the easier parts. The harder parts include getting the nib/feed properly set and tuned, and properly replacing the J-bar. If you're lucky though you just need to do the re-sac.

    I've just watched the episode. No talc! Shocking!

    I pronounce it "Wivern" whereas Laurence pronounces the Y.

    Should the J bar be replaced also?

    Only if the lever is loose/rattling when the pen is used, or the old J-bar broke and fell out. If the lever is tight and the old bar is intact, keep it in the pen.

    Go to Richard Binder's site, he has a page that lists many pens and gives their sac sizes along with guidlines for general purpose sac size estimation. It is either on the page on re-saccing pens or a separate page itself.
