Parker 45 nib removal from collar when feed broken

[donnweinberg]

I need help in how to remove a Parker 45 nib from its black collar when the feed has broken off from the back of the collar.  Here is a photo of two such broken units that I have:

 

 

When dealing with an intact unit (intact feed), one holds the feed in one hand and slips the collar backward with the other hand along the length of the feed, and then the nib falls right off.  But with a broken-off feed, there’s nothing to hold onto on the feed side.

 

Has anyone successfully removed the nib in this situation?  How best to do it?  All reasonable suggestions are welcome.  Assume that I have ultra-sounded the unit in solution in advance.  Thanks.

Just put the back end of the feed on the table top and push down on the collar.  That should be enough to shift it out of place and slide it the rest of the way off.  If not, once you have it as far as the end of the feed, use the narrow end of a chop stick to push farther.  Or the back end of a drill that's smaller than the OD of the threads.

Hi, Way West,

 

I don't have a P45 at hand presently, so I can't say whether it will work, but:

what if you press the back of a pencil (or any other piece of wood) [shaped to

a suitable diameter] and press that onto where the feed was?

Ron's first method is easy and effective.

I thank those of you who made suggestions, all good.  Good news:  I was able to remove both nibs, essentially using the Ron Z method.  I first soaked the units with Pen Flush in an ultrasonic unit, and then applied finger pressure against the respective collars to separate them from the nibs.  The separation occurred within a few seconds, and the parts are intact.  Happy days!
