Sealing A Parker 51 Hood: Is Shellac Really Needed?

Thanks for the responses - I'll probably be sticking with shellac (I need it anyway for a few other pens).

 

 

Is there supposed to be an o-ring in the aerometric? I don't remember seeing one when I took mine apart. (then again, it appears to be a bit of a frankenpen - it has the aerometric filler from a "regular" i.e. "non-Special" 51, a silicone sac, the feed + ink collector + nib from a 51 Special, and some sort of flexible plastic or glass feeder tube. I get the feeling I wasn't the first to work on my pen...)

 

Some aerometrics have 0-rings, some don't. If there is a groove between the threads and clutch ring, and the threads cut away at the edge of the shell, it should have an 0-ring.

I've been using Ron's rosin thread sealant for years (Ron's French's Mustard). Never had a problem with leaks or removing the hoods when necessary. As moderator maybe Ron cannot advertise his products or maybe he's not selling it anymore, but it works better than shellac!

I'm not likely to quit making the thread sealant until I quit the business. My efforts here are to help people with repairs, so I don't push the stuff I sell.

I am interested in learning how to disassemble my Parker 51 aerometric. If there are basic instructions on how to do this, can someone point me in that direction? Thanks.

There used to be a pinned topic starting like "Now you have your first 51 . . ." that discussed it. Looks like it was unpinned. Faded back.

Check out Youtube. There are some very illustrative videos on this subject.

And a WHOLE lot of bad information. Not the place I'd send someone new to all this.

I find that the guys who are really good and qualified to make a video don't have the time to make instructional videos. Those who do are often over confident about their skills and qualifications i.e. "Hey, I've successfully restored a couple of these, so I'll make a video telling how to do it!"

 

Go to a pen show repair seminar, or buy a copy of the Marshall/Oldfield repair book. Better yet, if you're in SF, go to a pen club meeting and have Farm Boy show you.

Or go to a pen show and watch Ron Z restore your pens which is how I learned to replace the diaphragms on vacumatics!

A very little goes a long, long way, your million isn't going to be made producing and selling this :-)

Come to think of it, there isn't a million to be made in our interest. It's for the love of it we persevere.

Some aerometric hoods have space for an o-ring and some don't. I don't know anything about why, but I discovered this when I needed to replace a hood and the parts vendor asked which kind I needed.

 

Edited to add: I should have said, some P51 hoods have space for an o-ring and some don't. Maybe it's the difference between the vac fillers and the aerometrics, or maybe it's something else.

That, and improvements in design and serviceability. Not all of the aerometrics have the 0-ring. The pessimist in me still shellacs the hood on, but if you have a fresh 0-ring, and use a little silicone grease on the shell, you likely can get away without the shellac. Older 0-rings can lose their elasticity, and don't seal as well, or they break.

 

Put a little silicone grease on a Q-tip, and run it around the inside of the hood, right where the 0-ring will sit. This will allow the shell to thread on without sticking or binding on the 0-ring. Simpler to get it on the shell than the 0-ring itself - and you don't need much, just a thin film.

I bought my Parker 51 from an antique store and when I had taken the hood off of it, it didn't have any shellac. Could Parker have forgotten to put its sealant on this pen?

      On my second trip to Japan in seven months, while the going is good

      Oh to have that translucent pink Prera! @migo984 has the Oeste series named after birds. There is a pink one, so I’m assuming Este is the same pen as Oeste.    Excellent haul. I have some Uniball One P pens. Do you like to use them? I like them enough, but don’t use them too much yet.    Do you or your wife use Travelers Notebooks? Seeing you were at Kyoto, I thought of them as there is a store there.

      It's not nearly so thick that I feel it comprises my fine-grained control, the way I feel about the Cross Peerless 125 or some of the high-end TACCIA Urushi pens with cigar-shaped bodies and 18K gold nibs. Why would you expect me or anyone else to make explicit mention of it, if it isn't a travesty or such a disappointment that an owner of the pen would want to bring it to the attention of his/her peers so that they could “learn from his/her mistake” without paying the price?

      Why nobody says that the section of Tuzu besides triangular shape is quite thick. Honestly it’s the thickest one among my many pens, other thick I own is Noodler’s Ahab. Because of that fat section I feel more control and my handwriting has improved. I can’t say it’s comfortable or uncomfortable, but needs a moment to accommodate. It’s funny because my school years are long over. Besides this pen had horrible F nib. Tines were perfectly aligned but it was so scratchy on left stroke that collecte

      @asota -- Yeah, I think I have a few rolls in my fridge that are probably 20-30 years old at this point (don't remember now if they are B&W or color film) and don't even really know where to get the film processed, once the drive through kiosks went away....  I just did a quick Google search and (in theory) there was a place the next town over from me -- but got a 404 error message when I tried to click on the link....  Ruth Morrisson aka inkstainedruth
