Engine Hook Cutting Guides for Estes Model Rockets

These guides fit over the top of the engine mount tube, providing a guide to cut the opening for the engine hook exactly 1/4-inch from the top of the tube. If the tube is the same length as the engine, this will result in a 1/4-inch overhang of the engine hook past the bottom of the tube. These can be used in conjunction with the corresponding Estes Engine Block Spacer Tools released earlier.
