BLUEBIRD 425,440 Studio Pugmills Instruction Manual

Efficient, compact, and portable, the Bluebird Models 425/440 Pugmills offer high quality wedging, reclaiming and extruding capabilities. Either is ideal when quantity of clay to be processed averages 700 lbs per month or less.

Some of the possible applications are:

1. Economical reclaiming in the classroom or small studio.
2. A transitional pugmill for the smaller studio or hobby potter.
3. Test or specialty pugmill for the larger studio.
4. Power extruder when fitted with owner-made dies.
5. A means to reduce physical strain of clay preparation.

Model 425 Pugmill
This model performs the basic functions of pugging, reclaiming or extruding. Over the years this unit has successfully met the needs of many classrooms and smaller studios or performed as a specialty pugmill in larger production settings. The majority of users find that the Studio Pugmill reduces hand wedging. Functional construction, ease of operation, and low maintenance are essential features of the 425.

Model 440 Vacuum Pugmill
Several factors have made the option of a vacuum system worthwhile to many purchasers; wide use of commercially deaired clay, varied and exacting fabrication techniques, and time- saving considerations. The Model 440 produces a dense thoroughly deaired clay ready for slab ware, throwing or extruding no additional wedging. Its vacuum system design is the same as that of larger Bluebird Pugmills.
