GENERAL DESCRIPTION
The Model 206B-MM Miter Mandrel is an accessory option which is used to expand
the versatility of the Model 206B BEVELMASTER
TM by allowing in-situ set up on
irregular pipe, fittings, and valves.
The Miter Mandrel is secured to the ID of the workpiece by way of (4) four
individually adjusted Jackscrews.
Once secured, two distinct types of adjustments are easily performed: Angular offset
and parallel offset.
Miter Mandrel
The angular offset adjustment allows the Mandrel Shaft to be precisely aligned with
the workpiece (even though the ID of the workpiece might be irregular) or it may be
adjusted up to 5
O from the centerline in any direction desired to give a mitered prep.
The parallel offset adjustment is done by adjusting the Jackscrews to re-center the
Mandrel Shaft after the angular offset adjustment has been made.
Both adjustments are accomplished with the aid of a Dial Indicator Kit.
