1. An apparatus, comprising:
a first idler having a proximal end and a distal end, wherein the proximal end has a thicker diameter relative to the distal end, the first idler rotatably mounted to a frame by a first speed-tolerant bearing at the distal end, the first idler having a hollow core at the proximal end and extending a portion of a length of the first idler;
a second idler having a proximal end and a distal end, wherein the proximal end has a thicker diameter relative to the distal end, the second idler rotatably mounted to the frame by a second speed-tolerant bearing at the distal end, the second idler having a hollow core at the proximal end and extending a portion of a length of the second idler; and
a shaft rotatably mounted to an inner surface of the hollow core of the first idler by a first plurality of heat-tolerant bearings and to an inner surface of the hollow core of the second idler by a second plurality of heat-tolerant bearings.
