I am building a Walter Umland Coyote kit and have found many uses for those wonderful CLC weights. I was trying to figure a way to stand the wing on the trailing edge in order to fit the shear webs. I also needed to employ the jig tabs still in place on the ribs.
I already had a box level clamped to the bench since I built the wing with the leading edge against it. I clamped a steel rule against the box level and stood the wing on edge with the jig feet against the rule. I used builder's squares to hold the wing vertical. I found that a CLC weight against the trailing edge was the perfect spacer to allow the vertical triangle to abut both spars and a rib. After setting up the squares, I backed them up with another steel rule and then loaded that rule with more CLC weights. Absolutely perfect setup, rigid and true and more than sturdy enough to allow the fitting of shear webs.
There are many ways to skin a cat and build an airframe. A lot depends on what we have on hand and how we figure a way to use it. Weights are great!
