Belt Tension Idea?

I’m a new owner of an X Carve and have been working through some of the basic issues
of a new owner.

One issue is the belt tension, but I have an Idea and was wondering if this is viable.

If you put a precision compression spring ( about 4 pounds) at the end of the tension screw
(between the nut and the end bracket) would it not keep a constant tension on the belt?
You would not completely tighten down the clip on the insertion nut.

I’m I thinking this through right?
