The North Star Big Blue Extruder does not look like or work like any others.
It is designed to be simple and safe yet powerful. This model features a 15cm x 15cm x 30cm (6" x 6" x 12") aluminium barrel that holds a full 11kg pug of clay and can produce extrusions up to 11cm x 11cm (4 1/2" x 4 1/2"), without an expansion box.
With this extruder, there are no heavy bars or levers to injure head or feet, no hydraulic pumps or air compressors with their inherent hazards. Instead, it is entirely hand driven. Turning the large handle drives a compound rack-and-pinion gear box which dramatically reduces the force needed to make an extrusion. No more than thirteen kilograms (kgf) of force at the handle is needed to make an average extrusion!
- The Simplest, Safest Extruders
- Wagon Wheel Handle 620mm diameter
- The barrel and die simply lift out as a unit (no tools required) so that cleaning, changing dies and loading can be done while you sit or stand comfortably at your work bench.
- The Wagon Wheel Handle is held in place by a quick release pin. It is removed with a pull so the handle can be quickly set aside whenever it is in the way.
Large Basic Hollow Die Set Included
Included with the Extruder you will receive Northstar's Large Basic Die Set and brace which contains the following 6" dies:
- 992A Round: 4 1/2" OD hollow
- 992B Square: 4 1/2" OD hollow
- 992C Hex: 4 1/2" OD hollow
- 1 x Customisable blank die
All dies are made of 3/4" Thick HDPE Polyethylene Plastic, and are CNC Machined for exact shapes.

Packaging was robust and assembly easy. Plastic dies were not as well finished as I would have liked and I had to remove some rough milling marks that transferred to the extruded clay. Easy to clean and reduced effort in operation have made life easier on my shoulder.

Amazing quality, I upgraded from the venco large wall mounted extruder which has parts that had to be welded fixed and very thin die sets. The big blue is solid and made from quality materials. Very happy with the investment.
