Homemade Wrench Tightens Nuts On Scaffolding
 ✖  |
Scott Testory, Farmer City, Ill.: “The second-hand scaffolding I bought to paint my house uses wing nuts to fasten the cross braces. I realized the nuts needed to be tighter when I walked around the scaffolding and saw the braces had become loose. I tried using a hammer to tap the wing nuts around, but the wings kept breaking off the nuts. So I developed this wrench to apply equal pressure to both wings on the nut as it’s tightened. It works great.
“I started with a 1 by 8-in. flat plate that was 3/16 in. thick. I drilled a 1/2-in. dia. hole about 1 1/4 in. from one end and then reamed it out one size larger. Then I put it in a vice fixture on my lathe and chucked up a 1/4-in. mill bit. I centered it in the previous hole and ran it out 1 in. in both directions. The last step was to round the corners and clean up the burrs.”
