A Versatile Spindle Lock for the Sieg SX4 and Grizzly G0720 Mills

I need to do some keyway cutting and came across this very versatile spindle lock for the Grizzly G0704 which I have adapted for the Sieg SX4 and Grizzly G0720. The main advantage is that once installed small adjustments to the alignment of the spindle can be made and locked.
I have not shown the making of the device as this can be seen if you visit Clough42's site at • How to Make a Spindle ... but I have included the dimensions in this video and have also made the Solidworks Model available as a download which you can find here
