[Above] Take the 2 inch piece and measure 1 inch from one end. That end is henceforth the bottom. Mark the center between the sides and put a dimple in that spot. I used a convenient nail here.
[Above] Now, using a 5/8 in. bit (or better, one just big enough for the nut,) drill a hole just deep enough for the 3/8 in. nut. You can see my hole is a little large.
[Above] In the center of the shallow hole you just drilled, now drill a 3/8 in. through hole. The threaded rod will pass through this eventually.
[Above] Now glue the nut in the hole using the epoxy. Try not to get the epoxy in the threads of the nut. It’s just easier that way.
[Above] Take the two 3.5 inch pieces and coat one side of each with glue. Glue them to one end of the 30 in. bar with the 2 inch piece between them. as shown. Clamp it and clean up the glue squeeze out.
