Miracle-gon Swenson. How accurately mark the entire roof rafters in 5 minutes

Hello, friends.

Recently in the hardware store I stumbled upon a funny angle. Previously, these could not see. I asked the seller: "What kind of animal?" He cryptically said: "square, which is a 5-minute mark on the entire roof rafters, even hip or valley." What can I say, intrigued Manager))

Buy this instrument itself is not yet decided, but brought help. Thing is really very interesting. And not only for roofing. I'll tell you briefly to the fact that he is able, and in the end give a link to the most complete video review, which could be found on it. Go.

Immediately apparent - a platform-abutment on one of legs of the polygon and a large number of scales. With a focus simple. It rests in the face of the board and can quickly otchertit angles of 45 or 90 degrees. Cloth gon, by the way, thick. Along it you can confidently conduct a jigsaw or circular saw. Conveniently! But let's deal with the scales.

External scale on the hypotenuse is intended to measure the angles in degrees. It is more convenient to use than a protractor. No need to put the risks, and then connect them with a null point. Focus rests in the board, turn the tool to the desired angle and immediately draw a line along the leg. Firstly, it is convenient, and second measurements more accurate.

Immediately reveal "secret markings for 5 minutes." Along the hypotenuse gon have a slot. Postpone the desired angle. We screwed into the groove (close to the beam), with the screw nut and obtain additional emphasis. With it, you can quickly set aside the desired angle on an infinite number of boards.

The second from the edge of the hypotenuse of the scale is designed for marking and valleys corner rafters. No need to calculate the slopes, and to calculate the angles of triangles formulas. Are putting on this scale, the main angle of slope of the roof and get the angle at which we need to gash angle rafter foot or valley.

The layout of the second scale can only be done at the same angle of slope of the main roof!

Next to the two major is another pair of scales. Their purpose is the same as that of the first two. Only angles not shown in degrees and in percentage. Such designations are found only in gravity layer flat roofs. Though can someone on pitched roofs come in handy. I did not come across.

Another nice option - the ability to quickly carry out parallel to the base line of the polygon. To do this, a separate scale. Insert a pencil into one of its slots and conduct angle along the boards. For example, you can quickly mark a spike.
