Pivotal tool support for a pipe machining apparatus

A tool support for a pipe machining apparatus, the tool support comprising:

• a one-piece unitarily formed body member defining a cavity there through;
• and
• a tool support arm at least partially positioned in the cavity and configured to translate within the cavity, wherein the tool support arm defines a groove therein;
• wherein the body member defines a receptacle in communication with the cavity, the tool support further comprising a guide member at least partially positioned in the receptacle and extending into the cavity where the guide member engages the tool support arm to allow movement of the tool support arm in a first direction and to inhibit movement of the tool support arm in a second direction different than the first direction, and further comprising an adjustable mechanism useable with the guide member to adjust the guide member relative to the receptacle and the groove.

A tool support for a pipe machining apparatus, the tool support comprising:

• a first translating member configured to translate a tool toward and away from a pipe;
• a second translating member configured to translate the tool toward and away from the pipe, wherein the second translating member is coupled to and translatable relative to the first translating member;
• and
• a locking member that selectively rigidly secures the second translating member to the first translating member, wherein the locking member is moveable between a first position, in which the first and second translating members are rigidly secured together and are not moveable relative to each other, and a second position, in which the first and second translating members are translatable relative to each other.
