Parker 51 Needs Nib Tune?

[eaudom]

Hi. So I got this 51 vac in the wild. Immediately filled it and started to write. the only way I could get consistent ink to page was to apply a lot of pressure, way too much pressure. So, I took it apart, cleaned up like new, ultrasonic on nib feed and breather tube. Air flows freely thru tube and breather hole. The nib slit looks right at the vent hole. then appears to decrease to zero just before the iridium tip. Put back together...still wont write well without a lot of pressure. Time to try to open up the nib slit?

 

By the way, I have another 51 with exactly the same issue.

Sorry about upside down Apple image.

Most likely a feed-nib-hood spacing issue.

Thanks, so maybe the nib is pinched onto the feed too tightly. Not sure how to create space.

I agree with Farmboy. Write with the hood off to see if the symptom disappears, before making any other change. Don't disturb the tine spacing until you can eliminate other factors.

ok, with hood off writes much better, still a little dry but much better. Hood back on, problem returns. So I think I have two pens with this problem. Solution? Fine sandpaper to increase the bore?

Is the problem that these plastics shrink slightly over time?

Thanks for the great help.

Hi Don, have a read of this thread. Basically, warm the hood , open up the cleareace a little. And don't wave the hood to dry it like poor gasman! https://www.fountainpennetwork.com/forum/topic/306136-51-writes-perfectly-with-hood-off;-barely-at-all-with-it-on/

Suspect feed is to tight on the top (slit side) of the nib.

Thankfully, it's hard to go wrong heat setting a 51 feed, if there are any other issues. A couple of photos of the nib and the feed would be handy!
