Abstract: A cutting tool attachment for a power tool is freely rotatable about an end of the power tool. A fence provides a complementary flat surface area for the cutting tool attachment to rest against a surface of the material to be cut. The fence prevents free rotation of the cutting tool attachment while in use. A handle allows a user to guide the attachment along the surface of the material, while also providing leverage to keep the attachment against the material surface close to the attachment, but at a safe position to reduce the chance of injury. A user can rotate the power tool relative to the cutting attachment to achieve a comfortable position or to help turn the attachment and power tool. The power tool is therefore positionable along a 360 arc of movement relative to the attachment while the attachment is positioned along the surface of a material.

Abstract: A process that uses a lodged projectile removal charge (LPRC) apparatus to remove a projectile jammed in a cannon's gun tube. The LPRC is positioned coaxially and offset from the projectile, and the gun tube is filled with water. The charge is detonated producing a shock wave that disintegrates the LPRC apparatus and pressurizes the water. The pressurized water produces a radial hydraulic force against an interior wall of the gun tube, an axial hydraulic force against the projectile pushing the projectile toward the chamber, and produces an opposing expansion of explosive gases that blasts out most of the water in the gun tube. The process is less likely to damage the gun tube. The LPRC may be made using a 3D printer.
