Hero 616 Nib - Hood Alignment: Changing with the Times

One of the reasons I harp on so relentlessly about the humble Hero 616 jumbo is this; it's very much an "enabling" pen. It has drawn me in to the wellspring of fountain pen lore well beyond the original "these are very easy on the wrist, could be handy for yet another week of three hour handwritten essay exams" rationale.

This inexpensive, mass produced plastic cigar has helped me learn about nib smoothing, tine alignment & flow adjustment, cap assembly, ink sac types and their properties, button filler mechanisms, vacumatics, aeromatics, collector, nib, feed and hood alignment - far more than could be reasonably expected of it. I probably owe my serendipitously disaster free resurrection of older pens (so far...) to the 616.

This post concerns a common "characteristic" of 616 jumbos - straight from the blister package, the nib can be off centre from the hood. This is purely a cosmetic concern, and they will still write without tweaking. You only need to start tinkering if the nib not being straight plain bugs you, or you temporarily want better access to the nib for smoothing, aligning the tines, or changing the rate of ink flow.

Bifurcation time! There are 2 paths to take here, depending on how the pen was put together at the factory, greased or sealed:

My most recent batch were stamped 2012, and their hoods are sealed on strongly. I'm not keen at all on stressing the thin plastic in attempting to get these new pens open. I recommend the safe and simple technique shown in the video below for sealed units.

This technique aligns the nib safely to a sealed 616 jumbo hood, never attempt the same on a Parker 51. I couldn't think of an amusing chiasmus to write here. Any ideas?

The three jumbo 616's I bought last year, on the other hand, had hoods that were made ink-tight with a mere smear of grease on the threads. I recommend the method below for these, as you really are better off with sealant on the hood threads rather than grease. This method is a bit more involved, but does get you some great hands-on experience should you ever need to open a very similar Parker 51.

First, here's the patient (click to zoom all photos). This is assuming a really badly put together pen, with the nib, hood, and feed all over the place, for ease of demonstration. I've never seen one come out of the packet this bad in reality.

 Flip the pen over, and it's so bad, the nib is even off centre from its feed (the black bit)

So unscrew the hood to take it off - unlike a vintage Parker 51, there's not much call for dry heat or soaking - and clean the grease off the threads.

 Pull out the white collector!

With a pull and push rhythm, the nib and feed can be pulled out of the collector.

Set the nib and feed straight, then push them straight into the collector. The feed should face the thin channel in the collector (though to be honest, judging from my experiments it doesn't really have to).

Leave all that out of the pen, and screw the hood back into place - not crazy-tight, just snug. Make a mental note of where it stops, or use a bit of tape, or something. Take the hood off again.

Push the white collector back into the pen, and turn it left or right till the top of the nib is aligned with the top of the where the hood was. You can screw the hood back on to double check. Once you are happy enough, apply sealant (shellac for example) to the threads, circled in red. With these pens, I'd be generous rather than conservative.

ta-da! Don't forget to let the shellac dry!

Hero 616 Vacumatic Take 2

Here's a shortish clip of my second vacumatic Hero 616 jumbo mod. I thought it would be more helpful to put the Mk.3 vacumatic content in a separate post to avoid any confusion, as I'll be giving that pen away.

The differences between the Mk.2 and the first 616 I converted aren't anything major. As part of a cosmetic change, the mark 2 got an alteration to the internal filler. Instead of  being mounted on an oversize washer with a rubber sleeve taking up the slack, an undersize washer was first slightly bored out, then hammered into place with a hollow drift. The friction fit between the two is very strong. Also, a presta valve cap was used in the blind cap,as it threads more nicely than the original woods valve cap for some reason.

A drill.
For both the Mk2 and 3, I figured out an easy and fast way to cut the blind cap without sawing it by hand, a real timesaver. The breather hole in the barrel was widened to accomodate a long VHS spindle.

The barrel is held in place between the spindle and a drill, the area to cut wrapped with masking tape, and spun fast as a 42tpi craft saw is held against the barrel. The resulting cut is quite neat. If you try this yourself, bear in mind the craft saw teeth cut on on the pull stroke, so set the drill to rotate the barrel against the teeth!
