Need Some Help With The Esterbrook Renew-Point Nib Unit Dimensions

[hari317]

I hope someone who has the nib unit and a pair of vernier calipers can tell me the dimensions noted in the sketch. I know the threads are 9/32inch 36tpi.

 

I believe the nibs themselves were longer or shorter depending on the series as I read from an article. It will be excellent if the longest and widest nib's dimensions can also be provided.

 

Thanks!

Hari --

 

here are the measurements from a couple of units I have to hand now. One is a 1555 the other a 2668, both fairly common. The third is a 2442 (which is installed in a pen and inked, so only a couple of measurements are easy to take.)

 

1555 / 2668 / 2442

A: 0.765 / 0.892 / 0.910

B: 0.515 / 0.515 / ...

C: 0.130 / 0.137 / ...

D: 0.400 / 0.385 / ... (I recommend you use B - C, it's more accurate!)

E: 0.250 / 0.251 / ...

F: 0.258 / 0.275 / 0.276

(all measurements inches)

 

Hope this helps -- I really enjoy making pens that take Esterbrook Renew-points, both my regular use pens are this type.

Duncan,

 

Thank you so much, Immensely helpful. I just bought a 9xxx series nib off Nishimura's website, so that I can make some trial units.

You're welcome, Hari.

 

Do be careful with that dimension A -- the first cap I made was the right internal length for one nib unit but destroyed another! It's probably best to allow extra space inside the cap (I usually aim to allow 1", but always check carefully the first time I screw the cap onto the pen.)

 

If you need other units, I have quite a few -- but they are the boring series 1xxx and 2xxx, not the up-market 9xxx.
