Collapsible and transportable systems for supporting miter saw assemblies. In one illustrative embodiment, a table assembly has two opposite main nodes at either end that support an upper bench top therebetween. Two legs extend from each main node to support the table. Two parallel support members extends through the main nodes underneath the bench top. A saw support table may be removably securable to the parallel support members extending out past the bench and allows a miter saw secured thereto to be adjusted such that the miter saw cutting table is co-planar with the bench top. A sliding locking member may be attached to the bench top to define a fixed distance for the length of material being cut. A second saw support table may be disposed on folding adjustable legs attached to the legs extending from a main node to support a table saw coplanar with the bench top.

An object of the invention is achieved by a method for cutting an elongated shell-type object. The method may comprise acts of providing a gantry defining a portal and comprising a wire grid operable in the portal; operating the wire grid, whilst moving the shell-type object through the wire grid along a lateral-axis (Z) substantially perpendicular to the portal.

The method is performed by a stationary gantry, where the shell-type object is moved through the portal. Thereby, the method is simplified as there is no need for a rail system for moving the gantry.

A system, a method and a collapsible and/or folding apparatus may use a wire loop to cut an object. The apparatus may have a wire loop connected to pulleys on a carriage attached to a frame. The carriage may move relative to the frame to direct the wire loop through the object. The apparatus may have arms on the carriage that may be folded and/or a kicker frame pivotably connected to the frame that may be retracted to reduce the overall size of the apparatus.

A foldable miter saw and folding method of miter saw are disclosed. The foldable miter saw includes a base unit, a workable, and a cutting unit. The cutting unit includes a support arm pivotally mounted on the worktable, a saw blade, and a driver. The miter saw folding method includes the step of biasing the cutting unit relative to the base unit and the step of rotating the support arm relative to the base unit and the worktable to change the cutting unit from a working position to a folded position, thus reducing the vertical space occupied by the cutting unit and facilitating delivery, storage and package of the foldable miter saw.

A foldable miter saw with safety device includes a base unit having a working surface and an axial holder, and a cutting unit including a rotating member, a blade, a driving unit and a safety assembly that has a safety switch and a safety member. When the safety switch is not operated, the driving unit cannot drive the blade to rotate. During the period when the rotating member rotates to drive the blade from a working position to a folded position, a free end of the safety member can be rotated downward under the action of gravity, so that the safety member can rotate to an anti-touch position where the free end is relatively close to the safety switch so that the safety switch cannot be operated, and the driving unit cannot drive the blade to rotate, which can avoid accidentally touching the blade to rotate.

A foldable miter saw with safety device includes a base unit, and a cutting unit including a rotating member, a blade, a handle, a driving unit, and a safety assembly that includes a safety switch and a safety member with a retaining section. When the safety switch is not operated, the driving unit cannot drive the blade to rotate. During the period when the rotating member drives the blade from a working position to a folded position, the safety member can fall downward under the action of gravity and move to an engaged position, the retaining section is relatively close to the safety switch so that the safety switch cannot be operated, which can also prevent the driving unit from driving the blade to rotate and can avoid accidentally triggering the blade to rotate during transportation after folding.

A foldable tile saw suitable includes a base unit including a seat body and a water tank, a connecting unit including a connecting arm having a first section and a second section, and a saw unit including a saw blade seat and a saw blade. The connecting arm can rotate between an approaching position and a distant position relative to the water tank around a first axial line to generate positioning. The saw blade seat has a connecting portion and a cutting portion. The saw blade seat can rotate between a cutting position and a folded position around a second axial line relative to the water tank and generate positioning. As long as the connecting arm is rotated to the approaching position, and the saw blade seat is rotated to the folded position, the cutting portion can be approached to the water tank, so the storage space can be effectively reduced.

A cutting apparatus and the method of operating same is provided. The apparatus includes a feed tower assembly configured to be attached to an object and a frame base plate movably attached thereto. The frame base plate has a pivotable arm assembly and an arm wheel thereon which accept a cutting member. A visual tension indicator is operably connected to the frame base plate and the arm assembly and configured to indicate an amount of tension applied to the cutting member.

A horizontal multi diamond wire saw cutting machine in a closed loop running in a coaxial motion toward stone blocks allowing a cutting force direction to each other, the cutting direction of DW is in horizontal motion-whether stone blocks toward machine or machine running toward blocks- and tension system made of one tension pulley because of one DW running within machine, in addition the running of DW is by several drive wheels, set of drive wheels run by one shaft in clockwise motion, another set run by another shaft in counter clockwise motion. Each drive wheel supported by sprag clutch which allow pulling DW for the cutting speed and allow DW to be tensioned in all drive wheels by one tensioned pulley which is tightened by linear stroke by a jack with a set tension value. Further, a portable machine to be held within block and cutting execution.

A telescoping tool includes a pole assembly, a driveshaft, a plurality of bearings, and at least one connection member. The pole assembly includes an outer pole and an inner pole. The inner pole is slidably received in the outer pole. The pole assembly is movable between a retracted configuration and an extended configuration. The driveshaft extends longitudinally in the outer pole and the inner pole. Each bearing of the plurality of bearings includes a driveshaft passage defined therein. The driveshaft passage receives the driveshaft therethrough. Each bearing further includes an end connection passage defined therein. The at least one connection member joins adjacent bearings of the plurality of bearings. The at least one connection member is disposed in the end connection passage of each of the adjacent bearings.
