Parker P51 Cracked Barrel ?

[JotterAddict62]

Greetings All,

What would you use to fix a cracked barrel on a P51 Aerometric barrel? Superglue, resin mix ?

Cleaning a P51 Deb and I notice the crack by the barrel threads near the date code. I know the crack will not effect the function of the pen, however it needs repairing.

 

 

 

Thanks to all that reply.

Superglue and pen repair generally do not mix. There are very few applications in pen repair that call for it's use. It breaks down in the presence of heat (warm pocket) and moisture (like ink).

 

The best thing to use is an industrial solvent weld compound that contains methylene chloride. Let it sit for 24 hours after solvent welding to let it harden before testing, let along blending the repair area. Wear rubber gloves and a mask.

Methylene Chloride

 

Tenax 7R or Plastruct

Remember -- Ambroid, Tenax, Plastruct, Tamiya are all pretty hot and volatile. I use them all regularly in my other hobby of scale modeling, so know them well with a range of plastics, usually polystyrenes. All of these scar plastics fast, so feather them in with a very skinny brush, preferably on the inside of the barrel or cap. Tamiya's extra thin cement is the most volatile of the lot and if you don't use it under a hood you'll feel the fumes immediately upon smelling them; you really should wear a mask and gloves, as Ron notes, although I don't. (I generally turn on the fume hood for lacquer thinner, laquer-based paint, and MEK but not the routine use of methylene chloride.) That said, it's wonderful for over-sealing a closed crack. Tenax is not as volatile as it used to be, but a jar that is not closed tightly will still evaporate in a week or so. Plastruct is good too, a little slower and thicker, but because it's a bit slower, will really scar. Be careful to use the right Plastruct -- there are several types. Ambroid is my go-to -- it's sort of midrange -- not as thick as Plastruct or thin as Tamiya. It's also getting a bit hard to find, even in the States.

If there is nothing special about the barrel, I would just get a replacement. Black Aero barrels are about as common as grey vac barrels.

The P51 Demi in question is blue. I do have another.
