Any other fountain pens with screw in converters?

[tim77]

I am surprised screw-ins are not more common.

 

 

I agree, although I just recently encountered one reason you might *not* want a screw-in converter:

 

My Mom's MB-145 developed a leak on the converter seal, but it remained undetected because the ink could not get past the screw threads. The ink corroded the brass, seizing the converter in place. Eventually it dried out and blocked the feed. With a normal converter the leak would have been obvious right away, and no damage caused beyond a little inky mess.

I never would have thought of that. I learned something today! I am guessing silicone grease would make the converter usable, once the problem was identified, but maybe it would be best to reapply grease every time the converter is removed? I like to take the converter out for cleaning.

 

I just remembered I had this sort of leak on a Pilot VP Decimo (non-threaded, of course), and I found out right away when the ink started pouring out the front of the pen into my pocket 0_0

That was a mess, and during an exam, no less.

Sure, but it's no different than putting silicone grease on the threads of an eyedropper-filler. Do it carefully, and it should be fine. Since fountain pen inks are water-based, you really shouldn't have a problem.

The threads of an standard international thread-in convertor are no where near where the feed goes into the convertor. Additionally the threads on a Leonardo serve as a back up to the friction fit. The convertor still friction fits in. The threads would only come into play if for some reason the seal broke.

 

Is this different in other pens? Like a mb?

My Delta Journal Grande has a delightful quality screw cartridge converter.

 

But, my favorite daily use fountain pen, the Cross Townsend, has gone for decades without a leak with a push on. So, i can't complain.

Montegrappa has at least one model that does (I don't know what model it is, the pen was given to me)

[Raymond3]

A new Leonardo Furore has a screw in converter.

 

So, probably all of this new line of pens uses them as well.

Yes, Delta used screw in converters, I think Leonardo has carried on the tradition.

Seeking input on a suitable backup screw in for a Delta

Cd'A, Visconti, Schmidt K6 .......?

 

 

Thanks

As mentioned before, Caran d'Ache uses screw type in some pens - I think Leman has it, my RNX has it. But Ecridors have push/pull types included (at least in my case(s) it was like that).

The threaded converters in my Delta Sea Wood and Leonardo Momento Zero pens are interchangeable.

[Karmachanic]

Thanks! Unfortunately, equally rare and hard to find. I've ordered a Visconti. We'll see.

yes, Leonardo is a "spin off" of Delta (i.e. some of the people working for Delta moved to Leonardo)

They probably have access to Delta's suppliers of "raw materials" and probably also have transferred to Leonardo a lot of the technical knowledge that was previously in Delta.

Have you noticed how the Momento Zero looks very similar also from a technical point of view to the Delta the Journal?

They also have access to many of the resins previously used by Delta.

No, but that's probably because I haven't even see the Delta 'The Journal'. I've only really 'heard of' Delta after the company has gone out of business, and so I wasn't particularly interested in finding out more about its pen models since I have no interest in buying secondhand (including 'vintage') pens. I only picked up our two Delta Sea Wood pens because they seem so awfully well-priced when a Japan-based(!) seller was offering his last NOS units as clearance stock, while I was shopping for Sailor and Platinum pens.

In addition to the ones previously mentioned....Achim Velte uses screw in converters

Visconti screwin converter does not fit Delta pen.

Contacted Frank at Fontoplumo. He'll have Leonardo converters available online tomorrow.

Also the Cleo Skribent uses threaded converters – optionally. Unthreaded, international standard ‘Pelikan- / Schmidt-type’ converters can be used (just as you can use standard international cartridges), but Cleo offers threaded converters too.
