    Default Parker 51 wide or narrow channel?

    I dissassembled my P51 for cleaning and servicing. When puting it together again i could not remember if the nib and feed align with the wide or narrow channel of the collar. I searched but some people say it goes with the wide one, others with the narrow and others say the aligment does not matter.
    Whats your opinion/experience/ knowledge on the matter?

    SBRE Brown says line up the narrow channel with the top of the feed. Here

    Thank you Chrissy. Yes that's one of the videos I've seen saying it is the narrow one. And I think is right. In fact when you observe the collector closely one can think that the ink will flow even if it is no aligned with the feed/nib, as the collector fins will distribute the ink all over the circumference so the feed will receive ink and hence the nib anyway.

    The Parker repair manuals from the era say that their research showed that it really didn't make any difference which channel was on top. Having said that however, I put the big one on top, and have for the last gazillion years.

    I must admit that when I took the hood off of one and cleaned it, I put it back together exactly how it was when I removed the hood rather than ensuring I was lining up one of the channels with the feed.

    Note that Parker stated the go/no go gauge should be used and if within tolerances the orientation didnít matter.

    It says some other fun stuff too. Follow Rons suggestion.

    Thanks to all. I'll go for the wide one, as Ron says.
    And maybe will try different orientations to see if it makes a difference, before shellac.

    I never shellacked my hood on and never had a problem with it.

    You're lucky. I've had many 51s come through the shop with complaints of inky fingers because the threads were not sealed. You might be able to tighten the hood enough that it doesn't leak, but that also puts stress on the threads, both hood and barrel, and on the edge of the hood, which can lead to stress cracks. Using shellac or thread sealant seals with without that stress.

    It used to screw on without needing to be too tight, just two or three normal turns, and it was always perfectly OK. It wasn't shellacked on when I got it, and never leaked any ink from anywhere, so I never worried about it.

    That was before I sold it. I don't have any Parker 51's now.

    I don't have any 51s and can only do the simplest of repairs at this point, so I'm not stating this as anything other than a question that those with more experience will hopefully answer, but mightn't silicone grease on the threads secure them well enough that shellac wouldn't be necessary?

    I know of one person that desires grease on the hood as a method because he likes to change nibs to suit needs. Acknowledged by that person it doesn't work well, that hoods spin and that they can leak ink but if you are willing to take that risk for the benefit of having a loose hood then go for it.


    I've not found it a problem to use shellac or a rosin based sealant in the few years I've been playing with 51s.

    Don't later versions have an o-ring seal on the hood threads?

    Rosin based sealant is pretty easy to make and can be purchased as well, if you don't want to tackle mixing your own.
