Wingsung 601 Vacumatic Filler

[truthpil]

I admire you guys effort, I've been too lazy to go on anything ; my excuse got to be the heatwaves around here already running for 2 weeks, yesterday I read 38°C ( Celsius ) ... and its in a shaded area ... I think I am going to melt soon.

 

I am thinking I would replace the barrel of the lake blue original diaphragm version of the 601 with a demo to show off how it work ...

 

We've had some hot weather the past couple days and my 601 has been dropping some extra ink on the page as I finish the fill.

Has anyone else experienced this?? When full, my 601 has just the right amount of wetness, but with the last couple drops of ink it has gotten too way and every once in a while a whole drop will plop on the page.

 

I've been grading hundreds of assignments and exams this week and about one in every 30 got a nice bright magenta blob next to the grade hahaha.

I'd assume the air inside the pen just expands under the heat... Same as it happens with eyedroppered pens.

Yes, that's exactly what's happening but I never expected such behavior from piston filler.

The important point isn't the filling system but the container for the ink. Once the ink is in this pen it is simply stored in the barrel, just like an ED. As you write, the volume of the ink is replaced by air - if it wasn't, you would develop a vacuum and the ink wouldn't flow. Hence, the air in the barrel expands from the warmth of the barrel walls, something that wouldn't happen with a converter, cartridge or sac, which are all surrounded by an insulating layer of air.

I bought one of these a couple of weeks back and I think it must be nos as it does not have the "jewel" in the cap.

Lovely pen, but after writing for a couple of minutes it develops a blob of ink directly under the nib. I wipe off the excess, but it does it every time I use the pen.

 

Any ideas guys?

Burping. You must be living in a similar weather as I do and there's technically no way around it...... Cold air expands when you warm them with your hands. I simply stay away from anything that holds ink directly with the barrel during winter days.

I had the problem with my first fill which was during warmer weather. The large ink capacity on these pens makes them a little similar to eyedroppers when it comes to burping due to hand warmth or the weather.
