Anyone Have A Leaking Problem With A Piston Filled Bologna?

[bugmd]

One of my beloved Bolognas has developed a strange leak. The ink seem to be coming thru a seam in the nib section, see red arrow. Anyone else ever have this happen to them?

You can unscrew the section from there.

Add a little silicon grease may solve the problem.

But be careful, don't let the grease go into the feeder.

Thank you sir, problem resolved.

glad your problem is solved

I just bought a used Omas Bologna with the same leak problem. Can someone walk me into the specifics on how to rectify this problem? How much force do I have to use to unscrew the section and which part am I unscrewing? Do I need any kind of sealant to glue the section back onto the barrel, or is silicone grease good enough. Thank you.

Take a look a the thread pinned at the top to get an idea: http://www.fountainp...-extra-faceted/

 

Basic steps are:

1. Unscrew section.

2. Clean off old section sealant (on the section and in the barrel threads)

3. Apply new section.

4. Screw section.

 

The section should just unscrew, you don't need to bother taking the rest of the pen apart. In fact it should be easier since the Bologna looks like it has metal to metal threads. Be sure to hold both metal parts when unscrewing to prevent pulling and loosening of the metal fitting in the barrel.

 

Omas for decades has uses a dark rosin based section sealant, so I suspect that's what they're still using even on a pen like the Bologna. Hopefully just by unscrewing it, you'll be able to open. Rosin based sealants soften with heat, but if you have a celluloid pen, you'll want to pay close attention to how much heat since celluloid has a rather low melting point. At one of my local shops that does repairs, they just unscrew with section pliers/grips without heat -- the owner has done it front of me on 2-3 occasions. On some I've been able to unscrew the section by hand (or with something grippy), otherwise I use section pliers.

 

Once you have the section removed, you want to clean the old sealant. After you've cleaned up the old sealant, rinse the barrel internals and section with water to make sure there aren't any bits of the sealant left inside which could clog the feed. (Whenever I've had leaks at that point on Omas pens, the sealant is typically dry and brittle, and tends to break into little bitty pieces.)

 

No glue! Many Omas pens are serviced by removing the section. So you don't want to prevent future repairs by gluing it shut.

 

Again, Omas uses a rosin based section sealant, which Tryphon and Tom Westerich (penboard.de), sell. Ron Zorn (mainstreetpens.com) sells a Sheaffer-formula thread sealant, which is lighter amber colored and also rosin based. Rosin-based sealants remain tacky/sticky and soften with heat (which is what you do when applying it). I suppose the tacky/sticky quality of the rosin-based sealants might hold better (less likely to unscrew on its own) than silicone grease. But silicone grease should work fine as a sealant if you don't have section sealant handy.

 

After applying the sealant -- remember a little goes a long way -- hand tighten the section.

 

I've used Ron's on a partially transparent Omas Lucens LE -- becauses it's lighter you don't see it -- which fixed my leak. Before that I always just took them to my local shop.

See this post. The section structure should be the same. You can screw hard because the Bologna has a silver section and won't break easily.

Silicon grease is good enough since it won't react with most of the inks.

You can also try the thin white tapes for pipe sealing.

As general rule of thumb for pen repair, use of white teflon tape is bad idea. It could lead to stretching and cracking of the barrel. Granted the Bologna does have a metal section and fitting in barrel, and so is likely to be more resistant, still I'd make extra effort to acquire the proper rosin based sealant Oma's uses, or 100% pure silicon grease to avoid a more costly repair requiring a trip to Oma's or a professional.

Thank you Eric for your help. I appreciate your advices and tips on how to disassemble the section with causing structural harms to the pen. I will follow your set of instructions and if any new issues arise, at least now I know who to PM.

[bugmd]

I used silicone grease to seal mine and it has worked perfectly, no further leaking. I greatly appreciate all the assistance.

 

 

Now if someone has any advice regarding repair of the double reservoir high vac filler system............

[eric47]

Visconti double reservoir I presume. Those are easy, you package them and send them to Visconti.

 

Visconti doesn't make spare parts available even to expert repairers, Aurora is the same. So if it's not something easy or easily obtainable, e.g. using a standard Bock feed rather than one with a V on it, then there's really only one place.
