today in the afternoon I browsed through some threads on FPN.
There I saw a picture of a modified TWSBI 540 nib done by Pendelton Brown to give them some flex.
I thougt this looks interesting.
In the evening when I heated up my Sauna (takes about 30 Minutes) the nib modification I saw came into my mind again.
This inspired me to do a nib Mod for the Ahab.
I call it the "Ahab - Ease my flex Mod".
So during my Sauna heated up I did the following.

I took the nib out of the pen, marked the orange area in the drawing above with a permanent marker and went to my workbench.
There I mounted a round grinding stone to my Dremel and grinded out the marked area.

Just put it on a block of wood and held it with my fingers (not mounting it to a bench vice as i did not wanted to apply pressure to the nib).
It´s not difficult, to do both sides took me about 10 Minutes.
Just try to do both sides symetrically.
I think everybody which have a little bit craftsmanship and a Dremel can do this Mod.

The transformation regarding the force needed to flex the Ahab was stunning.
I took away about 2,5 mm in height (deepest point).
When I measure right across the nib from deepest point on the one side to deepest point of the other side the width left is 6,5 mm.
Now the Ahab is with respect to the force needed to flex about on the level of my 50s semi flex nibs (a little bit easier to flex than my Pelikan 400 NN).
I think you can easily adapt the amount of force which is needed to flex by grinding a little bit more or less away then I did.
For my preference the amount I did is perfect.
I also don´t fear that the Mod weakened the material of the tines too much.
It is still enough left, so don´t worry about that.
I was finished with the Mod, reassembling the pen and doing a writing test right when the Sauna reached it´s temperature :-)

So i wanted to share my experience with you as I know that many of you also do not like the huge amount of force which is needed to flex the Ahab.
The Ahab is also with the modification not a high quality pen but you can transform it to a "real" flex pen regarding the force which is needed to flex it.
And this is needed if you really wanted to use it as a flex pen, otherwise your writing will never look natural (you can see the pain in your hand using a lot of force when flexing it in the writing)
It still stinks, it does not work out of the box, the material is soft and cheap (my much cheaper Jinhao 159 appears much better from material perspective), it railroads a lot without feed modifications (had to cut off several fins and deepen the ink channel and still it railroads sometimes)...
Till now I considered the Ahab as my worst pen (I also wrote down my experience with it here: http://www.fountainp...ost__p__2587808 ), but maybe I have to reconsider this judgement with this Mod.
So i hope you consider this Ahab - Ease my flex Mod review as helpful. :-)
