I got a nice deal on my first Esterbrook at a pen show today. It's a 2668 and I got a lower price on it because there is a lot of resistance when unscrewing the cap.

 

When I got home today, I examined the cap threads and noticed that they are pitted in places. I gently ran a dental pick through the threads a few times, removing some black power, and applied silicone grease to the section. This smoothed it out a little, but it's still pretty tight.

 

I don't mind the tightness so much, but if there's something easy I can do to make it a little looser, I'd be happy to try it.

 

Perhaps the tightness will somehow also improve the seal and keep the nib from drying out?

 

Side note: I filled it with Parker Quink. At first the pen wrote a bit dry, with slight skipping, but now, a few minutes later, it's unbelievably smooth! I hope it keeps writing this well.

Get a screw thead pitch gauge from harbor freight for about $5, and use it to "chase the threads" to clean them up. That should help. Be careful, because it is plastic.

Baptiste knew how to make a short job long

For love of it. And yet not waste time either.

Too late now that you greased it, but I would have use a cotton swab dampened with water to dissolve the ink (the black powder) from the threads.  That might still work, but the grease may prevent the water from getting to the ink to dissolve it.

The cap may have also shrunk making it TIGHT on the barrel.

 

Did the seller resac the pen?  If not you will want to plan to get the pen resaced.  Because if the sac is original, it is over 60 years old, and could fail at any time, making a MESS.

I didn't mean to confuse you. The threads actually have divots missing from them; I don't think there's actually any ink in the threads any more.

 

Yes, the pen was restored. He didn't like how tight the pen was, so he sold it at basically cost.

Firstly, 2668 is the nib style, that appears on various Esterbrooks.  It is okay to clean away "dirt", but pleas do not remove any material.!  The cap and body might be "mis-matched", or the threads may be worn.  You wouldn't want to break anything.  A tiny bit of silicone lube is okay.  

 

Worst case, you have a nice Esterbrook, with a rough-fitting cap.  Far better than an Esterbrook with stripped threads.  

 

There are things about a 65-year-old that can't be fixed.

Get a loupe and look at the barrel threads closely.  A tight fitting cap can sometimes be an indication of a crack in the barrel at the threads.
