All that remains now, is to drive in marker pins at regular intervals along the arcs. The separation between marker pins will depend upon the radius of the arc. The larger the arc, the greater can be the separation between two marker pins. For these two arcs with radii of less than 5 metres, we would typically use marker pins at 600-900mm separation. In the absence of an automatic or laser level, we can use a straight edged timber and a good spirit levelto transfer the level from point R to points L and M, and then add 35mm. Small boat levels, 200-300mm long are not usually accurate enough for this sort of work, and so we recommend a spirit level at least 1200mm in length to be accurate when transferring the level by means of a straight edged timber, 3 to 4 metres in length. However, it is obvious that even a 4m straight edge will not span the distance from R to L or M, and so we set up a temporary intermediate level. Using a straightedge and spirit level to transfer levels Our Profile Boards have also been approved under our Project Kaiyo™ initiative as they have been manufactured from sustainable softwood timber.

Spray Paints are suitable for permanently marking nearly all types of surface and general purpose non-toxic wax Crayons are available in many different colours and are suited for marking on nearly any surface. We have various types of Chalk for temporary marking and our engineers Chalk is specifically suited for metal, specifically steel. The SCCS Chalk line (refills available) are perfect for drawing straight lines on concrete, plaster, metal. Using two tape measures, these can be used in place of arc marking, provided that you can anchor the tapes ends securely at points A and D. Pull the two tapes towards point E, and where the 6m mark on the tape from A meets the 10m mark on the tape from D, is exactly point E. Drive in a steel pin to mark the point.

Working Lines and Levels

Finally, we also offer Road Pin Protection Caps to help extend the life of steel road pins. They Prevent the deformation of road pins caused by excessive hammering. The dimensions on the drawing states that the distance from the left hand edge of the front doorway (A), to the right hand corner of the property (C) is 7m + 3m = 10m. However, most landscape plans are drawn at a scale of 1:100 or greater, and will usually have an accuracy of around ±50mm.

static void sm_config_set_out_shift ( pio_sm_config *c, bool shift_right, bool autopull, uint pull_threshold) has been chosen as the length of the base line A-D because it is a multiple of 4, the largest side of the 3-4-5 triangle other than the hypotenuse. The base line is regarded as true (accurate - a genuinely straight line), and so the longest available edge, ie, the '4' always goes along the base line. static void pio_set_irqn_source_enabled ( PIO pio, uint irq_index, enum pio_interrupt_source source, bool enabled) Point Y is similarly established, by levelling across from the line established between K and R at point X. However, at this point, we do not want the path to fall towards the house, as we did for the previous point, as there is no gully at point X. Therefore, we will set Point Y at 10mm below point X.

Point Q is established by extrapolating the line N-L until it intercepts the line K-R at point Z. The taut string line will just touch the pin at Q, which can then be marked for paving level. For our right angled triangle we need to be as exact as possible with our measurements to ensure we get a true right angle at 90°, and not at 88° or 91°, so a measure is made along the front of the house, from the LH edge of the doorway at 'A' and a distance of 8m is marked with crayon or chalk at point D, just to the right of the garage door. We know that the gully at K is 90mm below R, so Points L and M need to be 125 - 90 = 35mm higher than point R, which means it would be 150mm - 35mm = 115mm below DPC level. The level for point Q is established by pulling the line tight from L to Z and marking the pin at Q precisely where it touches, so that the line L-Z is what is referred to as a 'flat bone' - a single plane, not necessarily "flat level", ie: no fall in any direction but a consistent, steady fall in one direction. We recommend the Setting Out Peg for marking out temporary fencing lines and for hanging small notice signs. This product has been manufactured from sustainable softwood timber and is FSC certified.
