Hello, I've recently repaired a few Sheaffer vac-fillers using the method I often see in these parts of drilling through the barrel to the packing unit and picking out the rubber and felt.
I then came across this method by Grandmia, in which he says that he soaked and heated the barrel, before using a dowel to knock out the packing unit for repair. I'm keenly interested in this method, what with the difficulty of alternatively picking out the packing unit through the barrel.
Has anyone else tried this? Approximately how long does the barrel need to be soaked? (I've been soaking for three days and the packing unit is not budging at all).

Any thoughts would be appreciated.
