In one aspect, a pipe machining apparatus includes a coupling mechanism adapted to couple a first section and a second section of the pipe machining apparatus together. The coupling mechanism includes a base defining an aperture therein, an arm adapted to selectively couple the first and second sections together, an engagement member positioned in the aperture in the base, and a separation member movably coupled to the base and adapted to engage the engagement member. The separation member is adapted to move to push against the engagement member and separate the first section and the second section. In another aspect, a coupling mechanism includes an arm adapted to selectively couple the first and second sections together and a resistance member engaging the arm and one of a first section and a second section of the pipe machining apparatus to which the arm is coupled. ## Claims ### Claim 1 A pipe machining apparatus comprising: a first section including a first portion of a frame and a first portion of a tool carrier;
