Do you need a lathe turned “mold” for tapered gun barrels? The main batteries on most ships have tapered barrels- these are the ones I have so much trouble with.
a long time ago, I used the tapered plastic handles from cheap hobby paint brushes as “molds” .
Don - it helps to have a tapered “master” - but isn’t absolutely critical. You might just go with a cylindrical one, longer than the part you’re making and a diameter equal or smaller to the smaller base of the cone. Then you just start to roll the part, shifting it a small angle at different portions of the part. You start parallel to one edge, and end up paralel to the other edge. Then, while glueing, you concentrate to get a nice, even seam, it helps to keep the “master” inside the part. After that is done, while the glue is still wet, you shape the already closed part and shape it to be smooth and perfectly round, and that should do it.
Hope it helps, have a nice day - and merry Christmas, by the way!

Here is another amazing example of a paper model…[t$t]

I’d bet my house that was plastic. Amazing work.
Does humidity not affect these things?
Hody Pawel :
I have to tell you my friend , that over half of my really interesting little ships and two big ones are Maly Modelarz ! they have nice assembly drawings if one doesn’t speak Polish . Shoot , I’ve even thought about learning that and Portuguese too .

Hi :
Pawel probably knows .Now for me As I build I spray the parts with Clear craft spray as I do it . This way the whole thing is protected from moisture ( I/e Humidity ). One final spray when totally finished and there you have it .
I have a full hull , two Masted ship I built years ago and didn’t spray The paper tube masts bent . I went and put a brass rod inside to straighten it and sprayed the heck out of them .They’ve stayed true for about ten years now .
Howdy!
Well if you’re living in a jungle, then the humidity would probably be something to watch for… But I just got out of a flat that was so humid that I had problems with maintaining my clothes in the closets in a wearable condition. Still, the paper aircraft I had (uncoated!) sat there for seven years without a problem. So that’s not a big thing. Well built paper models have lots of “frames” inside them, to keep them stiff, that helps, too. Those masts that bent probably did this because of the combination of humidity and load.
Thanks for reading and have a nice day!

Well , Good Morning PAWEL !
Here I sit replying again ! It’s 7;10 A.M. my time .I got to thinking , ( I know , for an old curmudgeon like me that’s dangerous ) You know of course , that ship moved across country twice too ! I believe you may be right !Thread ( even silk fly fishing line ) is affected by humidity.
The thing is fully rigged including running and standing rigging . Still one of my favorites . The objects you can get are somewhat daunting sometime .I was thinking of DON’S reply when I looked at my Nuclear Plant ( The cutaway model ) There’s about twenty or more inches of piping visible on it . I learned real quick how to make tubes ( I/e Pipes ).
I also use this trick .I dampen the paper after I’ve cut it to size ( with a little overage ) and using rubber bands let it dry after rolling it around something like a piece of brass tubing .That has worked for me many years now . . There’s a Paper-Model website and one fellow was building a humongous freighter ! It was a training tool used by the British Maritime to make sure crewmen knew their ship top to bottom in the Merchant Navy .It’s over five foot long ! Every frame , doubler and flange is there , believe you me . Well , You have a good day and thanks for following this . Tanker - Builder
