OK I have a 45 nib in front of me.
When you pull the wings out, I am pulling on the outer corner of the nib at the widest point of the nib just before it starts to taper to the tip, not the tines themself. This has the effect of opening up the slit between the tines.
I figure there are at least 3 ways to do this.
#1 as Bruce said, lay the nib down inverted (wings up), and push the wings down, CAREFULLY. You are pushing the wings/shoulder of the nib outward. This causes the slit to open up. I think this is an easier method than what I did.
#2 slight modification of what Bruce said. Lay the nib down (with the wings on the table) and push the top of the nib down, CAREFULLY. You are pushing the wings/shoulder of the nib onto the table and pushing it outward. This causes the slit to open up. I think this is an easier method than what I did.
#3 (mine) is to hold the nib in your hand, thumb on top of the nib, finger nail of your index finger under both wing. Then pull the wings up, while pushing down with your thumb.
I think #1 and #2 is easier to do than my method.
You WILL get ink all over your fingers when you are doing this. Because you have to reassemble the nib assembly to test and disassemble it to adjust. So wear latex gloves, or be prepared to SCRUB your fingers when you are done.
