This is a tutorial to make a stone pattern around a round tower. (i admit that i snot probable that anyone wants to do a tower)
Here is the tower, roughly cut from Styrodur. It is the so called with tower.
The original

and the first steps to build the copy

For the builds of the two round towers on the castle i used slices of my plaster copies to get around the curve and remodelled the joints. The diameter of this one is a lot smaller and using slices was not an option as those would be so small, that hardly anything worth would be left from my stone pattern.
That's why i needed an alternative. I fellow german modeler gave me the idea i will show you now.
After i made a silicon mould of a wall section i used wood glue, applied two or three times, pure, and letting it dry nearly completely inbetween the layers.
A quick dry process is needed (i placed it near a radiator) as the glue has the tendency to retract and leave millions of air bubbles.



That's the look when it's dry

The glue wall (what a name!) is easily removable from the mould


With some more wood glue i am glueng it to the Styrodur, prepainted dark (to be sure that nothing blue will shine through)

That's the look of the tower now

The black color shines through it.
The glue wall is to smooth anyway and because i also fear that it is not really well accepting paint, i treated it with a mix of sifted earth, glue, plaster and a bit of water.
I wipped it well away after to let the stones stand out. It looks more like a real wall now i think.



Next update wil be the building and tiling of the roof on top of this.
Cheers
