Is there any hope? There's a first time for everything. AFTER I dropped it, I bought it.

It could be repaired, but I would want to sleeve it with a piece of celluloid and solvent weld the parts together, since the barrel holds the ink. It would be cheaper to replace the barrel though. Fortunately, they're available, and relatively inexpensive. Now if it were a carmine red, or an oversize, I might think differently.

Thanks for your reply.

I agree with your assessment of the pen. I have others vac fills, so I hope this can be this will be a learning process. What solvent you would use? I tried using some Tenax on this type of barrel, but it had no effect. Perhaps the product was too old, yet it did weld some polystyrene stock just fine. I have used it in model building and have used it on other pen repairs, but on this barrel it seemed not to work.

The sleeve is a good idea. I am glad you mentioned it. I assume the sleeve would be on the interior of the barrel, yet the piston must have room to travel, so I assume it must be very thin material. The only celluloid I am aware of is in pens and film stock. Do you have a source for the celluloid that you suggest?

Thanks.

Bump - hoping Ron Z will see my last question.

Tenax is methylene chloride, and is used on polystyrene. The solvents available to you for repairing celluloid are acetone and MEK. The stuff I use is not available to the average person.

You do have to be careful if you want to sleeve the barrel prior to repair. You will have to bore out the two pieces to accept the sleeve, and make sure that the ID matches the original at that point so that ink can flow around the piston washer, both when filling and when writing. I can't see that the cost of the lathe time and labor can be justified given how inexpensive a replacement barrel would be.

The barrel wall isn't especially thick at this point, but you still might get away without sleeving, but you need to know what you're doing. I've done it several times, but it can be a bit of a tricky process. Easier to do on a pen where the barrel wall is fairly thick. You'd want to check the inside for a ridge in the barrel.

Thanks again, I'll look for another barrel.

Hello!

The MEK you are referring to, would that be methylethylketone ?
What about teterahydrofuran aka THF ?

Cheers!

To all:_____________
Is it usual to see a pen barrel break this way? I always thought that the plastic used in these pens was pretty tough and flexible.
