Waterman 452 Disassembly Suggestions Needed

[Guest Ray Cornett]

I have a friend asking me to repair her grandmothers Waterman 452, a hard rubber pen with a lovely sterling silver filigree overlay.

 

 

I can do the sac and cleaning of the pen but my concern is how do I properly remove the section from the pen to replace the sac considering it is hard rubber.

 

Any advice is be greatly appreciated. Thanks in advance.

richard binder has a good basic info section on sac replacement

black hard rubber is in my opinion one of the easier ones to work on. hard rubber is pretty resistant to heat compared to celluloid or the various plastics and the black hard rubber does not suffer from brittleness as much as the other colors of hard rubber. waterman 52's have a straight friction fit section so it does not matter which way you twist it when you are removing the section from the body. the hard rubber section should pop easily out with just a little heat from a hair dryer or low powered heat gun and a firm but gentle touch, but if the section is not easily budging do not force it. keep your fingers near the area where you are heating. as a rough rule of thumb, if its too hot for your fingers its too hot for the pen

Thanks for the great information! Sac replacement I can to easily. It's getting this one apart that is my current challenge. It'll happen.

I guess one last question I have is about the section itself. Where does it actually stop? At the threads for screwing on the cap? Or down next to the filigree band?

the area where the section grips the body of the pen is roughly the same area as the threading. there is a little variation from model to model but yours will likely be pretty identical.

I thought so but had to make sure. Thanks!

I just had the most unbelievable stroke of luck of the year so far and it was with this very pen. I might have to celebrate with some of my favorite scotch as a result because man it was stressful at first.

I happened to smell the section joint and it was obviously rosin based so I held it tight in my hand for a few minutes. My hands get really hot sometimes. Then I gave it a couple very easy wiggles and heard really light crackles so I knew the sealants hold was breaking. So I spent about 10 minutes pain stakingly slowly jiggling the section and rotating the pen and repeating as to not just wiggle in one direction and maybe warping anything and it started to come out mm by mm and then it was free. The sac is literal dust except a few chunks that came out after I worked the lever.
