Fibercrete, aka papercrete, inventor Mike McCain created many types of mixers. His idea to use angle iron pieces welded together, then slid onto to rod inside a drum is simple to make. And this mixer is powerful to use in chopping and mixing papercrete. After talking with Mike I started calling these blades a "scissor" design because of the action of the blades, and the name has stuck.
A pair of normal hand sissors cut paper or fabric by having a moving blade pass by a stationary blade. In this pictorial of the design two spinning blades whirl past three stationary ones. Mike reveals, in his old video, (may be available soon as a DVD for sale) this scissor mixer chopping and blending a full drum of papercrete in just two minutes!
It is powerful and simple.
You need an outside power source to turn the rod that causes the blades to spin. To be most successful use an auto/truck differential to power the
blades. Some experimenting has been done using a 1hp motor, with not
the ability to give the same fast chopping and mixing, but it did mix. And if you are 'mechanically' minded you can design a drum mixer that can be wheeled to where you need the papercrete to be used. (added information on using a motor is provided- based on the design and work done by a third party.)
This parts photo series shows each individual part of the blade parts clearly, and also assembled onto the rod.
Parts: 2" or thicker angle iron, cut into pieces. 1" diameter or larger pipe cut to size, a matching shaft rod, two heavy bolts. Welding is required.
These assembly photos do not show how to attach to a power source, this is a parts pictorial only.
