Knocking Out Waterman's Nib/Feed

[cgfolks]

I recently started restoration on a Waterman's 52 in a nice cardinal red, but I have run into a problem I have never faced before. The nib and feed will NOT budge. I was able to remove the section just fine but the nib and feed have not moved a millimeter from my efforts. I have tried heat and grippers to remove by hand and I even used more heat than I am normally comfortable using to remove a nib and feed and it did not budge. I then moved over to my knock out block, I again used an excessive amount of force to knock the nib and feed and it still would not budge. I then tried dripping some mineral oil into the section with a syringe and let it sit for a few hours in an attempt to either lubricate the section or loosen some dried ink, then tried knocking again, still not even budging. I am running out of options here.... Obviously I wouldn't soak the section in plain water but could I try an ammonia solution without damaging the hard rubber? Any info or suggestions help, take care everyone.

Heat the section's outside surface but not so long as to transfer much heat to the feed.  Knock  out the feed.

sounds like you already have a nib block - rest section with nib pointing down in block, drip in ammonia solution from top with eyedropper to remove caked on ink

I am happy to announce that I have gotten it out. I used your method of dripping ammonia into the section continuously then I heated the section and pulled the feed and nib out with rubber grippers, thank you for your help.

no probs, glad it worked out - i read about the ammonia method on fpn from an old thread quite some time ago when i was having trouble with a vac nib - wealth of knowledge available on this site
