Determine whether the given program can (at the time of the call) be loaded onto the PIO instance starting at a particular location. 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. When the surface of a pavement exhibits a change in gradient, this may also be reflected in the edgings or kerbs. On the plan below, the marker pins have been positioned at 750mm centre to centre (c/c) along the arcs. Once in position, a taut string line can be fastened to the pins to create a line guide for the laying of the arcs. Our Profile Boards have also been approved under our Project Kaiyo™ initiative as they have been manufactured from sustainable softwood timber.

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. Insulated Fence Pin: Used with temporary fencing, our robust and highly visible non-conductive fencing pins are available in standard (plastic spike) or with a metal spike, more suitable for installation into tougher terrain. Supplied in lengths 600mm / 900mm

Setting Intermediate Levels

On larger projects, automatic levels , theodolites, laser levels and even GPS are used to assist in the setting out, but there are some basic setting-out skills that require nothing more technical than a string line, an accurate spirit level, a tape measure, a handful of marker pegs, preferably 12mm steel road pins, and occasionally, a calculator, all of which should be readily available to most diy'ers. Please keep your proof of postage from the Post Office until we have confirmed that we have received your returned items.

UK Mainland excludes Northern Ireland, Scottish Highlands, Offshore Islands and the Channel Islands.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.

Now we have R, J and K established, the next critical levels to set are the high points on the driveway, on the break line L-M. We can measure that from the centre point of the break line L-M to the furthest gully, K, is approximately 10 metres. Using the standard 1:80 fall, we can calculate that the midpoint on line L-M needs to be...... static void sm_config_set_in_shift ( pio_sm_config *c, bool shift_right, bool autopush, uint push_threshold)

Steps for the simple setting out for a building

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. static void sm_config_set_out_shift ( pio_sm_config *c, bool shift_right, bool autopull, uint pull_threshold)
