Pelikan 100 ink flow fine-tuning

[stoen]

Hello,

Can someone please give a more detailed description for ink flow adjustment in vintage 30s Pelikan 100 (not M100) with ebonite parts? I am familiar with the following:

1. ultrasound cleaning of the nib/feed/collar assembly prior to disassembling

2. taking the assembly apart and cleaning each part with water & ammonia if needed

3. fine adjusting the depth setting ratio between nib and feed (the deeper the nib, the lesser the flow)

4. with #3 ratio adjusted, adjusting how deep are the both being set into the collar (the deeper the both, the lesser the flow)

5. upon having #4 adjusted, dipping the assembly into hot water to adjust the adherance of ebonite parts to the nib. This fine-tunes the response of the ink flow to the writing pressure.

6. Cleaning the interior of the ebonite grip with both ultrasound and water/ammonia if needed.

7. Testing the air-tightness of the piston

8. Screwing in the nib assembly back into the grip and inking.

Repeating the steps #2, #3, #4 and #5 until the right amount of flow is achieved.

(Similar procedure probably also applies to all Pelikan pens up to M&K 400NN.)

Is there still something I may be missing?

Thanks in advance!
