Abstract: An indicator holder for holding and positioning an indicator, such as a dovetail dial test indicator. The indicator holder includes a mounting assembly for attaching the holder to a machining apparatus. The mounting assembly includes one or more connecting members and an eccentric offset member. The central axis of the offset member is offset a distance from the central axis of the connecting member, with the two axes being parallel. The indicator holder includes an upper arm that receives the offset member of the mounting assembly such that the upper arm can rotate about its axis to enable alignment or zeroing of an indicator mounted within the holder. The indicator holder has a slide plate pivotally connected to the upper arm and a lower arm pivotally attached to the slide plate, with the lower arm including a guide way receiving and retaining the mounting element of the indicator.

Abstract: A tool for cutting a plastic pipe includes an annular collar having a fixed inner diameter which adapted to be slidably positioned on and encircling the plastic pipe. The tool further includes a cutting member pivotably attached to the annular collar an alignment ring having a fixed inner diameter which is adapted to be slidably positioned on and encircling the plastic pipe abutting the annular collar. The tool includes an element for maintaining the alignment ring in temporary engagement encircling the pipe, with the annular collar abutted next to the alignment ring.

Abstract: A tool for cutting an elongated pipe is disclosed which includes an annular collar selectively positionable on the pipe for slidable movement along the length of the pipe to a predetermined position and separate selectable rotational movement about said predetermined position. A cutting member is pivotably mounted to the annular collar, so that as the annular collar and cutting member are rotated about the predetermined position, a circular score is formed on the pipe. Further rotation of the cutting tool results in cutting of the pipe through the score. In a preferred embodiment of the present invention, the annular collar includes a radial expansion slot for expansion of the collar and frictional engagement of the pipe to be cut, the cutting member includes a blade mounted between opposing first and second blade holding members and a biasing spring attached to the first blade holding member with a fastener.
