Sheaffer Plunger Rod Lenths

[es9]

Is there a way of determining what length rod should be used? For example, is there anyway of knowing based upon the length from the end of the barrel to the part inside where it flares out?

There were something like 11 different sizes of plunger rod.  I have a table somewhere that gives length based on model.  I should find that and scan it.  But the table doesn't help unless you know the model number.  The best way is to copy the length of the rod you have.  The critical dimension is shoulder to shoulder, not the overall length of the rod including the threads.   The later can be almost anything.

Thanks, Ron. If you end up finding that table, it would definitely help. I’ve seen at least one website that translates a lot of the model numbers.
 

Subbing is generally my preferred approach. And I’ve found that using a rod a few mm longer or shorter usually works too. My problem is that I have a couple of pens that are missing the rod entirely. Not sure how it happened, but it’s where I’m at, unfortunately.

Rod length for Balances, hope it will help. Lengths for Triumphs are also available, but they are separated on different pages.

I will usually make new rods according to the actual pens, rather than these data, some of them seem strange.

Thanks! Do you have a method for determining rod length based on the barrel?

Put the barrel toward light, then measure the length between the packing unit and the wider area in the barrel, the rod should be a little longer than this length.

Thanks! Any guess as to approximately how much longer, on average?

Not sure, maybe 2-3 mm? Some extra length will be OK, if not, just make another one.
