The MT 1 Mandrel Saver prevents bending of the Mandrel Shaft, which may occur when using a tailstock centre point into the end indentation of your mandrel. The mandrel shaft goes through the hollow end of the Mandrel Saver live centre.
The Mandrel Saver presses against the bushings with zero pressure on the mandrel shaft. The tube and bushing assembly tightens up by turning your tailstock quill adjustment wheel.

The mandrel saver live centre is a specially designed live centre that has a 6.2mm hole through its centre that slides neatly over the mandrel shaft and steadies the shaft whilst turning the pen. The mandrel saver live centre is tightened onto the pen bushings to grip the pen barrel without putting any pressure on the mandrel shaft. This action prolongs the life of the mandrel shaft when compared to the use of the knurled brass nut to grip the bushing, with the point of the live centre pressing into the end of the mandrel shaft.
When using the knurled brass nut to hold the pen barrel, any overtightening of the tailstock with the point live centre puts the mandrel shaft itself under significant pressure and can cause it to bow. This bowing of the mandrel shaft will cause a type of off-centre turning and produce pen barrels that are not completely cylindrical in shape (ie slightly oval).
The mandrel saver live centre removes all pressure from the shaft since the shaft itself is free in the centre of the mandrel saver. The life of the mandrel shaft will therefore be prolonged and the pens turned using this specialised live centre are likely to be superior to those turned using the knurled brass nut to grip the pen barrel.
