to its surface when not supported by some strong background.
In cutting out the bristol board for building or architectural and engineering models a bevel-edged woodworking chisel should be used; a knife or shears should never be used as they will fracture the material and produce raw edges, which mar the perfection of the model. In modelmaking, as in everything else, the best tools are always the most satisfactory.
It is recommended that the chisel used for cutting bristol board and cardboard never be used for any
other purpose. Even the sharpening of a lead pencil will spoil the cutting edge, and it will be necessary to put the instrument on the oil stone before it can be used again.
The author has used, with considerable success
and satisfaction, a set of English wood carving tools, especially where small scale models were to be made. In cutting the bristol board for a model there should be a block of hard wood under the board. Some practice is necessary in order to cut ‘bristol board successfully; the method suggested is to hold the handle of the tool firmly and press downward until the edge has cut through the board. Never draw the chisel along cutting line as you would do if using a knife. After having accurately and carefully cut the different parts of the model they should be assembled and held together by glue lightly applied to the edges that are to join. A base should first be provided, and this is to be cut to the size of the inside bottom floor measurement.
The walls should be glued in place separately,
