#511 Build a 2-56 Nut Wrench

Two Completed Wrenches
I looked online for a 2-56 nut wrench and couldn't find one
so I decided to build two of them from materials I had on hand.
The Nuts Need Tightening I modified an Athearn engine by adding NWSL wheels and a motor and this called for wiring in place of the stock Athearn electrical system. I could not get the 2-56 nuts to tighten down using pliers as the pliers did not grip the nuts well and the jaws were too thick.
Selecting Brass for the Wrench Body A piece of brass rectangular tubing (3/32 X 3/16) was the same width as the flat areas of the nut. Since I needed a pair of wrenches, I cut two pieces 2" long.
Selecting Brass for the Wrench Arms 1/16 square tubing was used for the arms. Four pieces were cut to 1/2" length. The arms have to cover the flat sides and accommodate one point of the nut.
Soldering Equipment Soldering equipment and tools. The gun is 30 watts. The liquid flux is from Ace Hardware. Remove the plastic jaw covers from the vise.
Holding the Wrench Parts in the Vise This is how the pieces have to fit in the vise or else the vise jaws act as heatsinks and the solder gun won't heat them. I held them with my fingers and then tightened the jaws. The liquid flux was poured over the parts, the parts heated, and then solder was melted into the joints. The excess solder was filed off after the metal cooled.
Two Completed Wrenches The finished wrenches. One of the arms broke loose when I used the wrenches for the first time, but it was resoldered. While these aren't fancy, they do work!
