Precision pipe etching mechanism

An apparatus for marking pipes at a plurality of cutting angles, the apparatus comprising:

• a marking plate of adjustable length comprising a plurality of apertures and a plurality indicators,
• where each of the plurality of apertures is of a size different from the size of each of the other of the plurality of apertures and is of a size to receive a pipe of a certain diameter through the adjustable marking plate,
• where each aperture is defined by a first half-circle side and a second half-circle side and the distance between the first half-circle side and the second half-circle side of each aperture varies according to the adjusted length of the marking plate,
• where the distance between the first half-circle side and the second half-circle side of each aperture is adjusted in increments corresponding to an angle of a pipe received through the marking plate with respect to the surface of the marking plate when the pipe is abutted against the first half-circle end and the second half-circle end of the aperture through which it is received, and
• where each of the plurality of indicators corresponds to a distance between a first half-circle end and a second-half circle end of the plurality of the apertures and specifies a diameter of a pipe received through the adjustable marking plate and the angle of the pipe with respect to the adjustable marking plate when the pipe of the specified diameter abuts the first end and the second end of the aperture at the corresponding distance between the first half-circle end and the second half-circle end of the aperture.
