Ink Flow Issue: Reverse Versus Normal Writing In A Kaweco Sport



arnoldlayne

Recommended Posts

I recently picked up a Kaweco Sport, which seems to have a slight flow issue (skips and hard starts) when writing normally, but which disappear when reverse writing. Has anybody had any experience with this sort of phenomenon, and what is it likely to indicate is the underlying problem? Does this suggest it is a flow / dryness issue, for example, that could be solved by making the nib a little wetter (writing in reverse obviously produces a finer line which does not need to draw as much ink)?

 

Thanks in advance for any advice from more experienced pen maestros...

I've never tried writing with the wrong side of a Kaweco nib, but I have found that some of them need a really good clean when brand new and never used.

My first thought is that the nib is a bit too high over the feed, too much gap for good capillary flow to bring the ink to the tip. When reverse writing your slight pressure is bringing the nib down closer to the feed and allowing good flow.

 

Look at my reply to this previiow posting, my first reply. This might help. It shows how to increase and improve the flow in a pen that writes dry and is hard starting. I have used some of these techniques successfully to make a new pen much wetter writing.

Both the steel nib on my sport and gold nib on Special were dry and hard starters and yes the nibs did write more freely upside down. Graystranger's recommendation is spot on; I rectified the flow on both nibs with 0.002" brass shim material. You can get a pack with a selection of sheet thicknesses from Amazon. In my limited experience Kaweco pens are not the wettest even when tweaked.

It is possible that there is too much gap between feed and nib, also another reason could be that the tipping is wider at the top than the bottom, so that when the nib is upside down more ink flows.

You could try sliding a sheet of paper between the feed and the nib, (under the nib) and see what happens.

If it goes in, then the gap is too much, the nib needs to be flattened to make it a tighter fit to the feed.
