Model 224B Miter Mandrel Head
GENERAL DESCRIPTION
The Model 224B Miter Mandrel Head is an accessory option which is used to
expand the versatility of the Model 224B BEVELMASTER™ by allowing in-situ
set up on irregular pipe, fittings, and valves.
The Miter Mandrel Head is secured to the ID of the workpiece by way of eight
individually adjusted jackscrews in two separate rows.
Once secured, two distinct types of adjustments are easily performed, Angular
Offset and Parallel offset.
With the Angular Offset Adjustment, the Mandrel Shaft can be precisely aligned
with the workpiece (even though the ID of the workpiece might be irregular) or it
may be adjusted up to 5° from the centerline in any direction desired to give a
mitered prep.
The parallel Offset Adjustment accurately re-centers the Mandrel Shaft after the
angular offset adjustment has been made.
Both adjustments are accomplished with the aid of an “Indicating Sleeve” and Dial
Indicator Kit.
