My " PF Tribute", being a tribute to the Sheaffer vac-fill features an improved integrated "plunger fill" system;
You can read all about two versions , being a transparent demonstrator & a red swirled ebonite version -earlier on this forum.
In the meantime there are several new versions coming on.
Making an efficient working & dependable filling system surely withholds new challenges.
Lets say its difficult but not hugely difficult with a good lathe & if one can make the neccesary tooling !
It surely takes a lot of preparation in designing & drawing the assembly & the parts
I aim to make a screw piston filler pen in the near future, a new challenge for me !

This point of curiosity actually arises from a review of one of Brian Gray's pens in the Reviews forum, and a comment I made there.
Has anyone here built a pen with an integrated fill system? What kind? Is it hugely difficult?
