I was hoping for a little advice on how to tackle my current pen repair problem.
I have a very nice vintage celluloid Waterman's, but the nib section is too loose (~0.6-0.8 mm in diameter difference). The barrel is not cracked and the threads tighten onto the cap perfectly.
Since the gap is a bit too large to accommodate for with shellac, I was hoping to get some advice on how to best machine and insert a sleeve of hard rubber or brass.
My questions are:
- Is hard rubber the preferred material? Or is a thing ring of brass equally viable?
- how thin can a sleeve of either material be made reliably?
- Must I bore out the ID of the barrel to accommodate the new sleeve? Or can i simply machine the sleeve to fit snuggly in the barrel with some adhesive (such as shellac).
- and for machining the sleeve itself is it best to machine down the ID or OD first?
I am a rather novel machinest and would prefer to keep my pen parts away from the lathe unless absolutely necessary.\
Thank you all in advance for any advice at all.
