I forgot to show the construction of the underside of the roof pieces so here are a few pics. Note the scored eaves wall....this is just a sharp point scoring the balsa wood to form planks.

The balsa form is just glued to the card roof....I needed to use contact adhesive here as the PVA glue was not holding. The end pieces are glued to the card roof but the two side pieces are glued more to the end pieces with only a small bead of glue affixing to the roof. This is because there is not much contact area between the sides and roof....it only contacts along one edge due to the roof slope.

Contact adhesive is cheap and cheerful from Lidl.

| contact adhesive...apply to both surfaces, let get tacky, stick together |
Moving on....tonight is about the buttresses. First I printed out the Dave Graffam paper skin. Then measured out the dimensions of the card former I would need taking into account the thickness of the card used. The patterns are cut from the paper sheet using a scalpel and the backs scored along the appropriate lines to ease folding. Each crease was folded so the paper takes the shape of the final pillar.

The buttresses formers were made in two halves. Each a right angle piece.

The angle was ensured by gluing in a right angle former...i.e. a Lego corner.

The glue used was PVA adhesive brushed onto one piece with a small paintbrush. Try to keep the glue on the card on not smeared onto the Lego corner.
 |
| Plastic clamps are invaluable to hold things together while glue dries |
Once the pieces had dried a little, they were removed from the former so any smeared glue did not dry onto the Lego. Any glue blobs were brushed with the small paint brush. The two pieces were glued together to form the full buttress. A small piece of card was added to the top and bottom to close out the pillar and to ensure the paper skin has a surface to glue to. This all takes time but ensures a strong finished part.

| Glue parts together and add end cap |
 |
| End caps on all boxes give a surface to glue the paper to. |
Finally he paper skin was glued to the pillar formers. The finished parts just need any white paper edges touched up with a dark marker or paint to hide the seams.
 |
| Making square forms ensures the paper wraps squarely around the parts. |
The buttresses will finally be glued into the corners between the wall and tower.
 |
| Adding butresses mimics real walls where they add support. |
 |
| Putting butresses into corners gives additional strength. |
See you all next time.
