I write science papers and have always wanted to publish something with the phrase 'veritable dearth of information'. Seems editors never think this is a good idea and it gets redlined out ....
In response to a dearth of requests, I have just created a Fountain Pen Sac Size Guide for Repairers.

A #16 straight sac is indeed a match for a Wearever Pennant. As is a 54mm J-bar (but note that the original J-bar has a ridge where modern ones have a channel, which means you'll have a slightly floppy lever).

Hey, anyone happen to know the correct sac size for a Salz Brothers Peter Pan pen? Just restored one and need a sac. I suppose I could just do it the old fashioned way and get the ruler out..... Much smaller than an Arnold mini which takes a 14,so guessing it may be as small as a 10. When I flushed the nib and feed I was amazed at how much ink came out. Thanks for any help! The pen actually turned out pretty well and cute!

From the responses so far, it seems reports of its dearth have been greatly exaggerated...
No problem in my mind which sac to use; I just love this quote!

Does anyone know which sac size (not length) I'll need to re-sac a Conway Stewart Dinkie 550?
Posted 07 November 2015 - 21:20
Do I understand correctly that these sizes are not the original but your proposal for a best fit?
Posted 16 November 2015 - 02:37
This has proven to be quite helpful to me. Thank you, Sir.

For love of it. And yet not waste time either.

What size sac would be appropriate for the modern Conklin Mark Twain Crescent Filler?
Posted 25 March 2017 - 14:37
I you are not sure what sac size to use, you can measure the size of the sac nipple. General sells a dial caliper with a scale graduated in 64ths of an inch. A nipple diameter of say 18/64 would use a #18 sac, 20/64 would be use a #20 sac etc. If you need to, you can go down a size, from 18 to 17 for instance, but not up because the sac would be loose on the sac nipple and would not be sealed or hold properly even with shellac.

I was previously trying to measure section nipple diameter by eyeballing it with a ruler. And I think that method inherently ends up with a slightly smaller value. As a result, when I bought some sacs recently, they turned out to be on the small side... enough that I had to shift my intended pens for installation.
Thankfully I discovered that I do have a digital caliper! And I confirmed that my previous measurements were smaller than actual.
I have a question though. Two pens I measured came out as 7.6 and 8.6 mm in diameter. What sac sizes should I use for them?
7.6 --> #19 or #20 ?
8.6 --> #21 or #22 ?
