1. A slotter for cutting a tube comprising:
- a first base having opposing ends;
a second base, having opposing ends, slidably connected to the first base by a pair of parallel oriented slide rods passing through the first base and secured to the second base for sliding the second base outwardly from the first base;
a receiving means, attached to the first base and to the second base, for securely and removably receiving the tube;
a cutting blade, having an upper surface and a lower surface, rotatably and removably secured to the first base, for cutting the tube;
rotation means for rotating the cutting blade;
a housing, attached to the first base, containing the rotation means therein; and
an over center linkage having a first portion operably attached to the housing and a second portion operably attached to the pair of slide rods for providing the outward slide capability of the second base relative to the first base and providing a fixed distance relationship for the second base relative to the first base.

Abstract
A slotter capable of providing a cut of precise depth into a tube is comprised of a main base and an adjustable roller base capable of extension and retraction from the main base, controllable by an adjustable over-center actuator linkage. A pair of roller sets securely hold the tube within the device. A cutting blade, straddled by a pair of limiting rollers, cuts into the tube. Cutting blade rotation is provided by a pneumatically powered rotational motor.
