Hello,

 

Although I figured out that my Sheaffer Craftsman takes in the standard #15 pen sac from PenSac Company, I still have following questions,

 

1. Which is better - necked pen sac or the regular tubular pen sac?

 

2. Is it mandatory to apply sac cement or I can stretch opening of sac and rely on its elasticity and the barrel opening to keep it in place?

 

3. What causes a leaky Sheaffer? Is the correctness of installing pen sac directly proportional to ink leaking from feed area?

 

Thanks for reading.

A straight sac is fine.  I rarely find necked sacs when I open up a pen.  Most of the old time pen mechanics used straight sacs, even on Parker Duofolds. You MUST use shellac to secure the sac to the sac nipple.  Failure to clean all of the old sac off of the sac nipple and to use shellac as cement can lead to a leaking pen.
