Mb 149 Full Flex Nib!

[leod]

I've explained in at least one other thread what I do to add flex to a nib, and why I do it. Here it is again:

 

Trim the sides of the tine to lower the shoulders. This makes the nib respond more like a vintage flexie than it would if I just left the original shape. Without this trimming, the tines flex only in the area toward the tip, and that is not how a vintage flexie works.

 

Remove material from the underside. This makes the nib more flexible.

 

Redefine the crosswise arch to increase the tine spread for given amount of pressure.

 

Retemper the area where underside material has been removed, to make the flexibility more precise and to increase the safety margin a little.

 

Regrind the tip to a more vintage-like contour.

 

Modify the feed as required for the additional flow a flexie needs.

 

I wondered before why it was made that way, thanks Richard for the detailed explanation.

Now i'm intrigue, can the same process be applied to a 146 (14K) to get the vintage Flexie?

Thanks Richard!

Yes, Richard creates masterpieces, but so is this art; wonderful!

~ Last year two friends urged me to look at a thread about a Montblanc Full Flex nib.

They knew that I used Montblanc fountain pens for field sketches when out with students.

There are considerable advantages to a finer nib with flex when sketching.

This thread introducing stevlight's Full Flex nib explains those advantages with images of both the nib and his drawings.
