A method of field shaping a laminated glass structure is provided. The method includes providing the laminated glass structure comprising a flexible glass sheet having a thickness of no greater than about 0.3 mm laminated to a non-glass substrate by an adhesive material. The laminated glass structure is field cut using a handheld power tool thereby forming a shaped laminated glass structure. An edge strength of a cut edge of the shaped laminated glass structure at least about 20 MPa.

In a method, substrate elements are provided wherein each substrate element has a first side and a second side meeting at a corner point. The substrate elements are picked and then placed on a support device in alignment. A cutting operation is then performed where each of the substrates elements are cut along a cut line having a common first direction which intersects the first and second sides of each of the substrate elements in order to create a third side on each substrate element. The third side of each of the substrate elements meets the first and the second sides at corresponding corner points.

A wet saw water heater is described. It is a water heating device that includes necessary components for assembly which are installed onto a wet saw water pan for outdoor winter construction use. For example, the wet saw water heater and plug includes a base component that is formed to selectively connect with a drain hole of the water pan while holding a heating element within the water pain. A heating component having a heating element is attached with the base component and a power cord is connected with the heating element that projects from the base component. Thus, the heating element can be securely affixed within the water pan to heat the water during use.

A system and method are provided for designing/creating, preparing, and installing a natural stone tiled surface at a site that provides a perception of randomness to the observer while actually following a predefined pattern that facilitates simple installation by unskilled trades and allows for the advanced preparation of the stone tiles used. Advanced preparation of the stone tiles allows the offloading of at least some cutting, preparation and installation steps normally required onsite, to an offsite location. The system relies on the tessellation or tiling of a specific outline of an irregular concave polygon, that itself includes an internal set of irregular convex polygon shapes. The tessellation of an outline that includes such a set of shapes provides an optical effect that makes it difficult for an observer to recognize the repeating nature of the stones within the patterned outline. The system can include one or more orthogonal reference lines to align with reference edges.
