Hi,

 

I'm not sure if this is the best place to pose this question because it is kind of a repair, but involves some fairly precision making...

 

I recently acquired this vintage Conway Stewart (student?) pen. However, the section is cracked as can be seen in the second photo.

 

From what I have read, repair on this part of the pen is seldom successful due to the pressure exerted by the nib on the section. The section plastic tube is no more than 1mm wall thickness, so the strength of any resin/glue does not have much to grip on.

 

My proposition is this, to craft a thin tapering ring (width 5mm, thickness 0.3mm ?), skim down the nib end of the section for a similar amount, and finally resin mount it. The ring could even round over the end immediately above the nib - this would impart greater strength, but may be more troublesome to construct.

 

 

Questions are:

 

1) Would it work ?

2) Where/how to make a precision ring - and out of what?

3) Is there a better way?

 

Have a nice day :D

 

E.

Questions are:

 

1) Would it work ?   - Yes, at least when the crack is also fused

2) Where/how to make a precision ring - and out of what?  -The front of the section should be reduced in diameter over a length of 5mm, so the ring fits over a cylindrical seat.

Doing so the wall thickness of the ring  becomes thick enough and one can  use a black hard rubber reenforcement ring .

3) Is there a better way? A replacement section is the only alternative...

Have a nice day :D
