GENERAL DESCRIPTION

The Model 212B SP Miter Mandrel Head is an accessory option which is used to
expand the versatility of the Model 212B by allowing in-situ set up on irregular pipe,
fittings and valves.

The Miter Mandrel Head is secured to the ID of the work-piece by way of eight
individually adjusted ‘Jackscrews’ in two separate rows.

Once secured, two distinct types of adjustments are easily performed:

Angular Offset
Parallel Offset

With the Angular Offset Adjustment, the Mandrel Shaft can be precisely aligned with
the work-piece, even though the ID of the work-piece 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.
