Outstanding. Great piece of engineering. You have got to make a video of this. Where did you get the plans? This would be great to see in action.

That’s six out of ten votes for a video! You have built an incredible device, I along with many others are contemplating spending a few hundred dollars for bench screws and you built THE MACHINE. Bravo PM me if you are going to do custom work.
