Bigger castings, melting and making alloy CNC parts with epoxy layer damping

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.

23 metal casting tips (which is also the video where we make the large z axis spindle plate). https://youtu.be/CCBsAKCMTME

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: https://ko-fi.com/floweringelbow/shop

Here’s Olfoundryman’s great video about pouring technique https://youtu.be/m6W71s-cd_0
