Paper hulls

[nosferatu]

Hello everyone,i need some advise about smoothing hulls using putty ,sanding and imprimation techniques,maybe this is answered in other thread,i know water and acetone putty are diferent products,but it´s no clear for me what should i need to use.Thanx!!

is that the biggest problems occur BEFORE you put the outer planks on
you have to "fill in" as much of the hull as possible before planking, and then smooth down the lines on your "inner" hull before you start putting on planks
trying to get smooth lines just after you plank will be a very frustrating process

Hi Kentyler,i know you´re right,but i still want to know how the work it's done,some paper hulls look like made of plastic and are very smooth!!!

the next trick is to use 2 layers of planking or hull covering
do the first layer and sand it down, then use putty to fill the hollow places
repeat until smooth

then do the second layer, which will be the "presentation" layer

depending on how the model is designed you sometimes have to adjust a little for the fact that you will be using 2 layers

Hello,i want to paint the hull ,but i don´t know the procedure
i.e.:Do i need acrilic putty?,some kind of coating before painting?

My best experience is with wall spackle. It is fairly dry and when dry, it sands easily. Acrylic paint such as Model Master or Tamiya airbrushed looks great when done.

Haa!!,really ?,it´s sounds very logic,because you can use a spatula for big areas,but does not produce any deformation??( water in the wall spackle, i mean)

Try to use it when it is not too wet. Don't put a lot on. Just enough to fill seams.

It's possible to build a smooth paper hull without all the puttying and sanding. Here is the tecchnique I have used successfully on a couple of ships.

This is just a variation of some of the methods already given above.
I apply strips of paper to the formers (which have been cut slightly small) and get a hull with flats between the formers. I build up the flat areas between formers with layers of paper strips, coated in wood glue until the flat spots have been built up to about the right curvature and then sandpaper the hull to its final shape. Sanding with a sandpaper belt that has been cut so it is a long strip, picks off the high spots and is a quick way to get a fair curve between the hull formers.
Check the hull with templates that are the negative of the contour of the hull formers you cut out, and check for right to left symmetry by eye and by using a carpenters contour gauge (aka profile gauge) ( (https://www.qy1.de/img/k309631.jpg) or (http://www.clasohlson.com/medias/sys...3735815198.jpg) ).
