CNC Clampdown Wasteboard Plans designed for STEPCRAFT D.840 and customizable to other sizes

A high-quality work holding wasteboard, like this one, is one of the best upgrades you can make to your CNC. This wasteboard is designed to use cam clamps, also included in the plans, to hold your work piece against the fence. They hold from the side of the work piece, making the top of your material free of any clamps. It uses .-20 t-nuts and can also be used with top hold down clamps using the same size bolt. Included are instructions on how to make it, a hardware/material list, the Vectric files for version 9 and newer, SVG files for whatever other design program you want to use. This wasteboard is sized out for the Stepcraft D.840, but may be modified to fit smaller or larger sized CNCs.

For further instructions on making the entire project, please see our Ad-Free CNC clampdown video for a general overview to see how everything is maade.
