In a pen servicing application, One is a glue and one is a sealant.

 

Although if used in its woodworking application then one is a sealant and one makes a mess ;)

Yes. You can also order from Kremer Pigments shellac flakes, varying shades, and dissolve it yourself. That way you can guarantee it's freshness. Here's a link:

Has it ever been mentioned what is in the shellac used for sacs? Is it the same as the shellac used for wood finishing?

It is. If you're interested, there's a post about it on my blog (link to the blog below). Mix it yourself, or use flakes, it's still shellac with the same basic solvent - denatured alcohol. There are different grades and cuts of shellac, but after a couple of decades of repairing pens I've found (as did Sheaffer) that basic off-the-shelf Zinsser orange shellac works just fine.... and I do still have some of my first pens. Not many, but enough to know that it outlasts the sacs installed. :)

Yes. One is used as "glue". The other is not. Get them wrong, and there will be "amusing" catastrophe.

You will glue your pen shut. :lticaptd: Or you will leak ink all over your clothes and hands. :lticaptd:

 

Seriouisly, think "Chapstik vs. Superglue". Now, doesn't that bring a smile to your face ?

Oh Lord. Now you've gone and done it Sasha.

 

How soon Now until someone asks which "Chapstick" makes the best section sealant?

Well, let's see. It's opaque (check), you have it around the house (check), it's slippery (check), easy to apply(check), repels water (does it repel water? maybe check) so it MUST be OK to use, right? Oh, and it's hydroginated something or another. Could be from a yak.

Okay. Serious question. A pen pal is sending me a 50 rupee eyedropper from India. I don't have any silicone grease sealant.

However, I have Chapstik (in four flavors) and (believe it or not) yak butter. How imperative is the grease ?

I now specialize in repairing pens that have been restored.

 

Use the cherry, the other flavors are less pleasing.

How imperative is the grease ?

Are you using it to seal the threads on the pen? I don't use an eyedropper, but I understand that they do tend to ooze a bit so some kind of sealant would be an advantage. I wouldn't use silicone grease, though some do. Silicone grease is a lubricant and doesn't fill the threads at all. Any "sealing" that you get really is from the hydrophobic properties of the grease. I'd be more inclined to use some of the was from a toilet bowl flange ring or bees wax. It's a bit sticky, spreads evenly, fills the threads a bit and seals reasonably well. I wouldn't use my thread sealant because you want to take the section out regularly to fill the pen, and the rosin based thread sealant is really sticky. I mean really sticky.

 

Does anyone else remember the Muppet Show episode with Gilda Radner, Beaker and Bunsen and their glue? It feels like that sometimes if you aren't careful.

Addendum to the post above.....

 

Note that I'm suggesting this for use in an eyedropper pen where the pen has to be taken apart regularly to be filled, not for use in other applications such as sealing Parker 51s, Sheaffer Triumph nibs, Parker Vacumatic and Sheaffer open nib plunger filler pens etc. In cases like that where the section/nib unit is supposed to stay in place long term, a rosin based thread sealant is the best sealant to use, not a wax or grease.

 

Some folks will counter "But I want to be able to take my pen apart to clean it." Contrary to popular myth, disassembling a pen to get everything squeaky clean is not a good practice. It can lead to leaks and/or other damage. Most pens were put together to stay together and to be used. That vintage pens can be taken apart to be repaired when needed just happens to be a bonus.

+1 to Ron.

 

Even if you don't break something, constantly taking apart your pen to clean it is causing wear to parts that weren't designed for that sort of constant opening, closing etc.

Sensitive Pen Restoration doesn't cost extra.

I didn't know most of these replies were here. Useful information and a couple chuckles are good to see when I wake up and check in. Much appreciated. And yes rosin based is super sticky. I really did not expect it to be set so well in just 5-10 minutes after applying. I had an issue with a pen section coming loose easily when I would brainfart and twist the pull cap. So I put in a little of my rosin based sealant and fixed the issue. Only problem is I wasn't thinking ahead. It's a cartidge filler I use a converter in. Don't do pen repair or fixups when you're dead tired. You don't think right. Luckily it's an easy fix.

      Even so, you'd end up with a fragmented list, and it becomes an O(N²) process for each prospective requestor to check what is available: effectively recreate the list of currently active servers (without any reliable up-to-date info upfront about the inks and number of samples on offer in the thread) from the sequential list of posts, which may be spread over two or even more pages, and then query each server independently to check what is currently on offer.   It comes down to not hav

      If one wanted to do this, one could just use the "About Me" field which appears to be unlimited in size.  And if a bunch of people wanted to cooperate, the Member Title field (or signature) could be used to this end - "Ink Giver" (or some such) could be used by those with inks to give...  No software edits required.
    • Arkanabar
      I suppose the update issue could be mitigated.  One would post a link in signature, to the particular part of your profile where you list the inks that you're willing to post samples to others, gratis.  But looking at profiles, I suspect that would require an edit to the board's software, potentially a nontrivial task.
    • A Smug Dill
      I read your idea as getting willing givers to publicly register as members of a set of heterogenous servers, in a system in which a client would explicitly select an available server from a list, to which he/she will then send a request privately and asynchronously. Request handling in the system is unmanaged, and individual requests are handled by the targeted servers completely independently on each other. I think the model is fine, although there are some operational concerns you may want to
    • Daneaxe
      First thought on the method/system of ink sharing: Think the best way, to begin with, is to follow the way of the US thread: offer up a (small) list of inks you are willing to PIF, to whoever expresses interest. Write clearly in the "mission statement" how it works, with a tiny "quid pro quo" that even a struggling student can comply with, i.e. post your opinion and a writing sample, with option of a full review if desired.   So yours truly might say: "I'm offering up samples of D
