These N53 mandrels are perfectly straight, high carbon, 36"Long (91.4cm) rods. The leading edges of these rods are chamfered for safe insertion. The other end of the rod is knurled for placement in the vise. We can make any size needed. These mandrels can also be used to keep slides straight during buffing. They are also used by those who prefer the traditional method of repairing dented trombone slides.
