Newbie error here,

I was attempting to re-sac a vintage Platinum cellulose pen when I over heated the barrel with my hair dryer, now there is a slight bend in the barrel.  Good thing the cap still threads on with no problem.  The problem is really aesthetics.  I tried one time to warm up the barrel with the hair dryer to bend the barrel straight but it did not work.  I thought I would stop there and ask the forum for advise.


So what is the best way to straighten the barrel with out distorting any of the threading or making things worse.

I would send it off for repair or live with a banana pen. Dewarping a pen is tough to do.

Not often successful and rarely a task for someone who is not intimately knowledgeable with the materials. You have to really know what you are doing with regard to heat, intensity and duration, and other aspects.


You might be best to just come to terms with your handiwork and learn to love a banana pen. It will be a reminder to you of what not to do in the future.

^^^ That.


This is something that I do try only when I have  to, not something that I like to take in as a repair.  Chances of failure are pretty high.


Straightening a warped barrel is really tough to do, and chances of success depend on the what the material is.  Hard rubber?  Possible.  Lucite?  Possible  Celluloid, maybe.  Acrylic, it depends on the type acrylic, and even then slim.  Some acrylics turn gooey very quickly and can't be straightened.  Then there's the chance that the material will bubble, melt or burn.

Hope it wasn't a MB straiated platinum, that would be a problem ;-)
