To make gypsum traction requires templates. For a simple traction or cornice, the template will be a regular board, inhabited by tin. To end it, you need to cut off a piece of sheet metal, strengthen it on the board. On top of the metal with conventional buttons, the paper circuit circuit is fixed, which is pricked with an awl. Having thus transferred the pattern to the metal, the paper is removed and finished with the contours of the picture, leaving allowances for sawing. Drowned (cutting out the board, made a contour. Extra wooden parts are cut off with a sharp knife to get a profile. One of the parties is granted with steel or tin, the other is cut at a slight angle, degrees 20.We mount the template
For installation of the template, be sure to take the board twice as long as the so -called “PART”. With a short run, the template will be unstable when stretching. Pay the profile board with nails to the lane. The angle of the template and the panel should be 90 degrees. The template is strengthened on the workbench, pressed the way to the rail, which directs. Plan to make a model with a thickness of four centimeters? To reduce its weight, you need to make thrust from gypsum with voids. For example, use clay gasket (up to 10 centimeters) or wood (more than 10 centimeters). Gypsum will easily separate from such a laying if it is covered with a thin layer of paper. The detail that you stretch should not be longer than a meter: you can curve the product.
Working for a workbench
So that the template is easily slipped, you need to lubricate the workbench. As soon as gypsum will begin to harden, it is laid out on a workbench. Penka is placed in the first gypsum layer for strength. Act quickly, otherwise the solution will freeze. Move the template smoothly along the rail, clutching tightly to the workbench. The movement of the template by part without iron is called “on the gloss”, a chopped part – “on the peel”. Move the template only forward. He is returned back to its original position, removing from the board. Put gypsum and repeat the movement “on the gloss” until the product is completely ready. Then they are waiting for the solidification. The excess from the product is removed by the movement “on the peel”. In the finale, the details of the gypsum are again put on the traction, move “on the gloss”, removing all the excess. Cut the ends at 90 degrees in traction made.
During the operation of the gypsum, knead in small portions, bringing to the workbench continuously. With the proper approach of the product (gypsum thrust) will be homogeneous, durable and smooth.
