With the Styrofoam? clamped and glued together the next step is to prepare the base for receiving the foam. To ensure that the model will detach from the towers, the dowel holes have to be covered with masking tape to prevent glue penetration. To follow the process earlier check out Armature Build (pt 3, page 3)

Styrofoam secured by quick release clamps until Gorilla Glue cures.

As you can see from the image, there is no lacking in clamps. It is better to have too many than not enough and have the glue spread the foams apart during the curing process.

The upper cabin area is clamped with no pressure blocks so the clamping face digs into the foam, preventing clamp slippage.

The image to the right shows the baseboard set-up on the modeling table. The dowel holes have been covered with masking tape to prevent the Gorilla Glue from penetrating the dowel holes and permanently fixing the body to the dowels. The glue has been evenly spread so as to provide uniform contact to the foam model.

The inner surface of the foam has been cleared of any excess glue that may cause a hang-up to the baseboard when placed into position. As you can see additional glue has been placed into the corners of the foam buck to provide good adhesion to the baseboard.

Baseboard covered with Gorilla glue ready for receiving the Styrofoam body.

Foam attached to baseboard using Chavant clay boxes as weights.

With the internal faces of the foam sprayed with water and a light misting to the baseboard the foam is carefully lowered into position. I made sure that it was seated completely by rocking the foam back and forth to bed the glue into the Styrofoam?

To prevent any lifting due to the glue curing what better weights to use than the actual boxes of Chavant clay. At forty eight pounds per box, two should be sufficient to hold a model this size in place.

To eliminate any glue falling onto the modeling table it is best to cover it with heavy duty builders paper such as Red Rosin Paper from Home Depot or Lowes. It is thick enough to absorb any drops during the curing process and makes for easy clean up after. When the clay modeling starts this paper will also be used to cover the garage floor so that I can contain the clay scrapings.

Clay boxes secure the foam in place.

The curing process for Gorilla Glue is approximately four hours before you can remove the weights and twenty four hours for it to be fully cured. All that remains to be done on the foam is to cut out the wheel house openings, this I will do once the glue has cured.

The process for cutting the wheel house opening is by making a template from the master tape drawing, this I will cover in the last section for armature build before commencing with the clay model. The final part on Armature Build (pt 3, page 5)
