Wild Crack Repairing Idea

[Fountainer]

So i have a cracked section of a hooded pen that leaks ink on my fingers. What if i would conceal it completely in plaster and heat it up in oven so that the pen part melts completely and reunites in to solid piece again? Then break off the plaster after it's cooled. Is there any hope or will it get deformed? Do i have anything to lose? Hopefully the crack is small enough to not take plaster in, nor there should be any air.

 

The pen is a black Lamy Panther, decades old but seems good quality. What kind of material are these anyway, i mean is it ever possible to properly melt this in the first place?

In my estimation there is minimal chance this would succeed.

So you are saying there is a chance That might be enough for me to go for it. At least i would gain knowledge and experience. Last time i explored another wild idea, was a success.

There is always a finite possibility that something will work. I think in this case my estimation of minimal is slightly smaller than I'd need to try.

If you do not know what is the material, please do not attempt a repair, unless the pen is valueless to you.

 

For known materials, there are methods known to work.

I'd think it would work for injection molded plastics, wouldn't it?

you'd have to make sure it wouldn't stick to the plaster when it melts, though. probably not a good idea, although I can see the temptation

FarmBoy has a tendency to be a bit facetious. I suppose it's also possible that you are too, and are trying to see what you can stir up.

 

Since I repair cracks I'll be more blunt. Your chances of ending up with a total melted ugly mess, or of having it burn, are infinitely better than the chances of it working. There is a reason why we solvent weld to repair cracks.

Excellent optimism.

I like those odds!

 

Absolutely, give it a go. Why not? (assuming it is a valueless pen and no people or animals will be harmed) - what have you got to lose?

 

But, I think Ron Z may be correct, re the end result.

And if you decide to go down a different path, there may be a better solution to the crack problem?

 

Still, let us know what happens.

Good luck.

There is no hope in plaster. I am the molding guy. There's no way to get it right. Material shrinkage and loss is way to much. At best, you get something like it came out of the other end.

 

Porosity is too great.

 

No second thoughts if you want to save the pen...Go with RONs cold welding

You could make a mold from aluminum instead of steel and just inject until the wear is excessive in the threads and toss the mold set. You would have essentially a lifetime supply of hoods.
