First steps in construction

 

I’ve cut out the base, end wall and one internal strengthener with no real problems, but I ran into trouble with the front left elevation which was the first to include window apertures.

I had bought a set of compass cutters a few weeks ago because I knew that with so many arched windows to cut out something was needed. I had anticipated that they wouldn’t be very much use for the small apertures – 3 or 4 mm radius semicircles – but should be OK for the rest. It turns out that the blade of the cutter flexes too much, with the result that they try to cut in a spiral shape rather than a circle. As a result, the eight arched windows on the front left section are a complete mess and will have to be redone. Fortunately the 40thou plasticard that I’m using will be clad with brick-embossed plasticard, so the join between the main part and the inset with the eight new windows will be hidden.

 

The process of marking and scribing the design onto the plasticard has been quite time-consuming, but useful. I’ve discovered two significant errors, both concerned with the lack of symmetry on the rear elevation, which I’ve put right and will save a lot of waste when I come to build the large dolls house version.

 

One and a half major structural pieces cut out, two and a half to go.

Check out my various blogs/posts about building construction.  If you have access to a computer with a DTP or CAD program, you can design your own windows including an aperture template.  Printed on adhesive paper, the templates can be cut out, stuck to the plasticard and then cut out.  It's quite possible to do the lintel arches 'freehand' using this method.  The together advantage is that all the apertures are identical dimension-wise...

 

I'd also question thewisdom of using 40 thou faced with embossed styrene.  I think you will find that the solvent sets up tension stress in the two materials and the result will be distortion.  I personally make up the main wall using layered 20 thou. A 'front sheet' - which has 20 thou spacers, separating a 'back' sheet also in 20 thou.  Once all the apertures are cut, the embossed plasticard can be attached and the apertures cut through.  For a better description see my 'Emsford Mill' forum entry.

I lurk on Buntbahn regularly for inspiration but had not seen that thread. Thanks for posting the link!

Yes, I had my doubts about the best choice for the main walls, principally because there are two curved walls.  If it turns out that my experiment doesn't work, then I will ahve learned something.  What I intend to do is bend the curved walls to the right radius using hot water and a suitable former.  Then bend the embossed layer to the same radius, then tack the embossed layer in place temporarily and use the holes in the 40 thou to mark the apertures in the embossed layer.  Then I'll remove the embossed layer, cut the apertures roughly, stick the layers together properly and fettle the brickwork edges.  Watch this space, it may well go very pear shaped!
