To be more precise, this is a conductor or template for uniform placement of the solution. Using such a template will not work to put more or less solution, it will always be as much as needed. Accordingly, the seam will be even. Such patterns are also on sale, and not under a single brick, as the master, but under double masonry, and under the side seam. Of course, an experienced bricklayer is device unnecessarily (although the master says that he put more than one thousand bricks "by eye"), but it’s quite useful for beginners.
This shape is ideal for laying bricks of the same size. If there are differences in the width of the blocks, the mold can be made using two thicker rods or put a piece of wood between the iron rods and the wooden parts so that they can work with a small gap.
According to the master, there is an opinion that with the help of such a device masonry takes more time. He claims, based on his previous experience as a bricklayer, that this is not so.
You can use any materials available to you, the master used the following:
Two metal strips about a meter long
Four trims
Two hairpins
Washers, nuts, screws
Drill
Screwdriver
Square
Production is extremely simple. We drill holes in wooden planks. On the other hand, we retreat 4 cm and fasten the metal strip. We carry out the same operation with all trims. When attaching the strap to the strip, align with a square. Then we wind the wing nuts onto the studs. We insert the studs into the holes between the planks (lamb inside). We tighten the nuts outside.
What else is good design proposed by the master? It has an adjustable width. Those. it can be customized depending on the width of the brick.
The only thing I did not like was the use of wooden planks. Over time, the tree becomes saturated with moisture, swells, fasteners loose. Probably, you need to make such a template completely out of metal or plastic.
Well, the video works with such a template.
