Rubber cement

Was it like this leak?

IANAN,

The leak was on the barrell side of the threaded silver band.

Mike,

 

If you've got an INK leak at that joint (the original post sounded like you just had an air leak), there's a leak in the sac....

 

This wanders from topic slightly-- I've an Admiral with an air leak at roughly the same point, and the only thing I can figure is a crack in the section. Can't SEE it, but logic demands it. If that's a snorkel, there might also be something amiss with the primary feed/tube, because that is a funny place for ink to emit from. Or the sac isn't well-adhered to the section plug-- I just had a TD let go this weekend because I clearly didn't use enough shellac on the nipple. So embarrassing! :embarrassed_smile:

I would say for sealing the blind-cap screw on a Sheaffer Touchdown/Snorkel, the best thing to do it what Sheaffer did - a small rubber washer that goes in the end of the touchdown tube where the screw goes in. Victor Chen was selling replacements for these, but they are pretty easy to punch - or try to preserve the old one if it is in good shape.

Model cement is solvent based (toluene or MEK) and works by softening plastics like polystyrene and "welding" parts together.

 

Neither is much use around pens I don't think.

 

Model cement I have seen is either Acetone of MEK. Both of those are used for celluloid crack repair to weld the cracked pieces together, often with the use of some sort of filler material of the same type as the pen (usually from a doner pen). MEK currently seems to be more in favor with the pros for a variety of reasons, though some like Richard Binder have other techniques that they choose not to share (due to toxicity, among other reasons).

Are you sure it is leaking at the section joint, not somehow leaking into the cap? That looks like an inky cap situation. If you are leaking ink at the section joint then I would also look at the sac.
