CFT Plans

Fabrication Shop Drawings. Now Available.

Michigan SoilWorks is thrilled to offer construction plans for its modular continuous flow vermicomposting bin.

The package includes fabrication shop drawings taken from the same engineering files used to manufacture the current production model manual drive CFT reactors.

This alternative is perfect for people in remote locations facing excessive shipping costs, and those who have the skills or access to local welding and fabricating talent to produce our CFT themselves.

The patented stainless steel cutting bar is also included!

Sample CAD Drawing from Your Design Package

The adjacent image shows a sample computer-aided design (CAD) drawing from the full design package you will receive.

This particular image shows the H-frame support employed at the ends of Michigan SoilWorks CFT modules.

This H-frame is actually created from 3 separate structural steel components, each of which have their own files to guide fabrication. Precise locations are marked for hole placement, facilitating fastener attachment and final assembly.

You can expect this level of clarity from all of our files.

A list of all the materials you will need can be found on the Materials List. Download the list, either US or International, and take it to your local fabricator to check for availability and costs.  There is also enough information there to make substitutions if needed.

Patented Cutting Bar

The cutting bar is a crucial component in a CFT.

An improperly-designed cutting mechanism can produce uneven harvest patterns and/or cave-ins.

In some circumstances, a cutting bar pulled by a strong enough motor can even destroy a CFT if the carriage does not maintain alignment during the full travel of the cutting bar.

The U-channel below our cutting bar glides smoothly atop the center rail.
