Opus 88 Koloro Flow Woes

[Bornin1992]

Hi, all,

 

I recently added to the collection an Opus 88 Koloro with a broad nib. I am currently using Diamine Terracotta.

 

From my understanding, turning the piston does not force the feed as it does with a piston-filler, and it uses gravity, instead. I have opened the valve, and rested the pen with its nib facing down. Only after 20 minutes will it start to write, and then it will dry up after two lines.

 

Any recommendations? I cannot imagine using this in any practical setting.

 

Thanks,

Opening the valve to 3mm should do the trick. This is my default position. No need to close unless engaging in gymnastics or flying. Just finished writing four A5 pages with mine.

Hi, that does not work for mine. Do you think mine is defective?

Did you flush the pen with a drop of dish soap in the water, then flush with plain water before inking? If not residual manufacturing oils may be your problem.

Yes, I did.

Return the pen

Return the pen as Muddy suggests.

 

Or, in dependence upon your confidence/skills, pull the nib/feed. Scrub the feed channel and fins with a soft toothbrush, and check the nib to see if the tines are too tight by holding it up to light, and looking with a loupe. You should see light from the breather hole, diminishing to the tip. If the tines are tight, spreading them is easy to do.

 

Of course, if you damage anything in so doing, you're on your own. So plan A would be best/safest.

Did you try a different ink?

[Gobblecup]

While not a piston, fully unscrewing, pulling out the rod, and plunging it back down will force ink through the feed to the nib and prime it. However ink will drip from the nib and you will probably want to dry the nib and feed with a napkin afterwards. In any case, also try other inks. I find that my Koloros can benefit from priming at times though. It is not meant to be done constantly but it helps when you first fill the pen and the feed is dry.

Before returning, and if you're uncomfortable also scrubbing the feed with a toothbrush, try changing inks. Some inks just do not work well in some pens.

 

You can also prime the feeds in these shutoff eyedroppers by unscrewing and re-screwing the knob completely, it will force a tiny bit of ink into the feed.

Another way to prime a shutoff valve ED is to unscrew the tail 2-3mm (open position), then un-screw the section halfway out. Invert the pen pointing the nib towards the mouth of an open ink bottle, and screwing the section back into barrel fully. This will force out drops of ink into the bottle through the feeder thus priming it.

 

HTH.

I'm returning it. Thanks for all your responses! I just think it is unusuable for my needs.
