by Michael Schwaiger *NEW VERSION* *MGN15H* *LINEAR RAILS* *STIFFER* *BETTER* *HARDER* Add these parts to your beloved Workbee CNC to stiffen the weakest spot on your screw driven machine to make it into a WORKBEAST CNC by changing out the shear loaded plastic wheels with a milled aluminium plate and linear rails. This helps to reduce chatter while cutting and is a great recipe to succeed in milling aluminium, hardwood and plastic materials. This mod fits the original aluminium plate and reuses some of the fasteners.
