Shape-Up Shaper Cutter Accessories — Rub Collars, T-Bushings & Shim Sets
A wood shaper produces consistent profiles at high production rates, but the quality of the output depends heavily on the accessories used alongside the cutter. Rub collars control the depth of cut by bearing against the workpiece edge, while T-bushings adapt different cutter bore sizes to a standard spindle diameter. Infinity Tools stocks the complete range of Shape-Up shaper cutter accessories for woodworkers running 1/2" diameter spindle shapers.
The Infinity Tools rub collars for Shape-Up shaper cutters serve as a bearing guide, controlling the profile depth by running along the edge of the workpiece. They are used in situations where a fence alone is insufficient for curved or irregular workpieces. The T-bushings for 1/2" diameter spindle shaper cutters are available in single units, 2-piece sets, and 3-piece sets to accommodate different stacking configurations on the spindle.
Precise cutter height on the spindle determines where the profile cuts relative to the workpiece face. The 4-piece shim set for Shape-Up shaper cutters provides thin metal shims for fine vertical adjustment of the cutter stack, allowing the profile to be positioned accurately without having to use the spindle height adjustment alone.
Setting Up a Shaper Cutter Stack Correctly
A properly assembled shaper spindle stack places the cutter at the correct height with a rub collar at the appropriate position relative to the cutting edge, and uses T-bushings to fill any gap between the cutter bore and the spindle diameter. Shims fill the remaining height to eliminate vertical play in the stack. Refer to the Infinity Tools learning blog for shaper setup guides and safe operating procedures.
