Casting the large spindle plate: It will fill our largest crucible right to the brim, but we are attempting to melt some aluminium in the new waste veg oil furnace, pour it, and make a casting for the large CNC machine. This will be the z-axis carrier plate – the part that travels the length of the gantry and provides a platform for the z’s linear motion carriages, ball screw and servo motor. See the CNC thrown together and in action here: Want to see our experiments with the y-axis gantry? video here: 23 metal casting tips (which is also the video where we make the large z axis spindle plate). The 3D model of the CNC AND a document explaining how to use DIY mixed 'metalized epoxy' to massively aid in machine building are both available for a tokenistic amount in our Ko-fi shop here: If you enjoy our videos, consider buying us a coffee Here's Olfoundryman’s great video about pouring technique Subscribe to Flowering Elbow for more DIY upcycling fun!
