Lathe BoringBar Set

There are three classes of General Purpose ACME threads, 2G, 3G, and 4G each class provides some clearance on all standard size diameters for free movement, and are used in assemblies with the internal thread rigidly fixed and movement of the external thread in a direction perpendicular to its axis limited by its bearing or bearings.

Designs should only utilize external and internal ACME threads of the same class and type, with Class 2G being the preferred choice. If less backlash or end play is desired, Classes 3G and 4G are provided. Class 5G is not recommended for new designs.

The Oneway Laser-Guided Hollowing System has been designed to make turning hollow forms easier and safer. A laser pointer is set so the laser light is offset from the cutting tip by the desired wall thickness of the vessel. As the vessel is hollowed and the cutting tip moves outward the laser light follows. Once the cutter reaches the desired thickness, the laser light falls off the vessel. Back arresting the hollowing bar reduces the strength needed to control the bar and controls twisting forces which allows the use of offset bars. Because the tips can be rotated, only three bars are required to hollow a 7 inch diameter sphere through a 1 inch hole with a 1 inch long neck.
