What that guy did is what I had in mind, except he made it self contained, so he had to attach things to the column. I was just going to direct the weights to hang of to the back side of my bench.

Since the screws on the taig are the same for X,Y,Z and the Z is supporting a much bigger load then the 7lbs he is using, I will have to assume that the screws are beefy enough for this.

I'll give it a shot to see how it works.

Thank you everyone.
