Great video Chris, Thanks!  What CAD?CAM system are you using?  You made it look so easy.

Hi Milton,

I use Solidworks to create the models (and drawings where necessary) and HSMXpress (a free 2.5D CAM Plugin for Solidworks) to create the G Code.  I find HSMXpress very easy to use, and I am becoming more proficient the more I use it.

HSMWorks (which is a full blown 3D CAM Package) is also a standard feature in Fusion360 if you have that CAD Package.

There are plenty of YouTube videos out there on how to use HSMXpress/HSMWorks.

By the way, the plastic impeller housing now appears to be standard on the latest Chinese coolant pumps.  I inspected some at my machine supplier recently.  So they appear to have recognized and corrected the material selection issue.

The good news is that the pump now starts to rotate every time I switch on the saw now.
