Tips on removing Jowo nib and feed from housing?

[DrManhattan]

I purchased a Jowo #5 from The Turner's Workshop and I'm trying to install it into a pen that has housing that can't be removed. I've been trying to pull the Jowo nib and feed out of their housing but I'm having no luck. I haven't tried twisting it in case the feed isn't circular. Any advice on how I can make this easier for myself? I only have access to very very basic tools.

Something to help give you a firmer grip on the nib might help, A piece of inner tube, one of those wide rubber bands used for broccoli in the supermarket, or a piece of honeycomb  shelf liner.

 

Hold the pen in one hand, parallel to the ground, feed down. Rubber stuff in the other hand. Wrap nib/feed with the rubber. Wrap the first joint of your index finger around the feed, and place your thumb on the top of the nib. Squeeze. Firmly, but gently pull the nib/feed and pen apart. Feel free to grunt, it may help 🤪

Repeat as required.

The housing isn't circular, there's a definite 'flat spot' that lines up with the bottom of the feed (assuming it's a standard JoWo housing?).  Karmechanic's advice is best, I think: if you can find a couple of pieces of inner tubing, and/or shelf liner, they should give you a firmer purchase on nib and housing respectively.  A bit of gentle 'wiggling' of the nib and feed can sometimes help - but twisting as you pull will almost certainly damage the housing.

 I think the problem in this case is how to grip the housing without having a pen to screw it in.

If he try to grip the outside part of the housing, he should pay attention to not use too much pressure otherwise he will make the extraction of feeder and nib more difficult.

In that case similar technique, except hold the housing  with thumb and forefinger around the front lip of the housing.  Might take more than one try. Could also try soaking the unit in hot water before trying to extract.

I tend to do these against a clean edge on a desk or table. With the nib tip facing down and against the edge, catch the edge of the collar on the top surface and use gentle pressure at the top (back end) of the feed to push it down through the housing. A hot water soak or a gentle warm up with a hairdryer beforehand definitely helps and go gently. I can usually do them with finger pressure alone and no need for any sort of knock out, but you might need to find an appropriately sized tool a thin bit of dowel, heavy bamboo skewer, cut off end of an artists paint brush or many other things will all work fine - keep them short to make them easier to manage without needing two extra pairs of hands!

 

Alternatively, do you have any other jowo 5 threaded pens you could pop it in temporarily just to do the nib extraction?

If you cannot screw the housing into another pen to hold it, you should attempt using some material that can make high friction so that you can apply horizontal force not perpendicular otherwise you will squash the housing and make it more difficult to pull out nib and feed, as fabri00 points out.

A large rubber band is your best bet, I use a piece of rubber sanitary plaster (those used as elbow/knee bandages) it makes gripping things much easier and also protects your fingers from the strain.

Hey everyone, thanks for the advice. I soaked the unit in hot water for about 30 minutes, and then gripped the lip of the housing using cloth and pulled the nib and feed out (also using cloth to grip since I had no rubber or anything like the things recommended) and it came out really easily.

Congratulations, good to hear it - the first time you pull a unit apart is the hardest, it should be easier if you need to do it again!

Interesting question.
