Installing Specimen Support Fixtures
You must bolt the specimen support fixtures (anvils) either:
• directly to the baseplate of the Model 8250, or
• to a T-grooved baseplate which, in turn, is bolted to the Model 8250 baseplate.
Refer to the following procedures for more information.
Direct-Bolted Fixtures
To install specimen support fixtures that do not require a T-groove baseplate:
1. Remove the T-groove baseplate, if installed.
2. Position the specimen support fixture on the Model 8250 baseplate between the
crosshead guide columns and bolt in place using four 3/8-16 inch (3/8 inch screws,
16 threads to the inch) socket head cap screws.
3. Verify that the tup and crosshead cannot hit any portion of the fixture. This may
require adjusting the height of the stop blocks or shock absorbers. See Chapter 5 for
more information on adjusting stop blocks and shock absorbers.
4. If the fixture is a pneumatic clamp, route the control hose under the back safety
enclosure door and connect it to the fittings on the side of the rear motor enclosure.
Refer to the section on Utility Connections and Initial Set-up. Also, make sure that
the crosshead and tup do not touch the raised clamp plate when the crosshead is on
the stop blocks or shock absorber snubbers.
T-groove Baseplate Fixtures
To install specimen support fixtures with a T-groove baseplate:
1. Bolt the T-groove baseplate in position between the crosshead guide columns, using
four 3/8-16 inch (3/8 inch screws, 16 threads to the inch) socket head cap screws.
2. Loosen the T-nut bolts on the specimen support fixtures and align the T-nuts with the
T-groove baseplate slots. Slide the fixture onto the T-groove.
3. Position the fixture and verify that the tup and crosshead cannot hit any portion of the
fixture. This may require adjusting the height of the stop blocks or shock absorbers.
Refer to the section called Adjusting the Stop Blocks and Shock Absorbers in
Chapter 5 for more information.
4. Tighten all fixtures and T-nut bolts.
