I made these today for mia_mcdavid, for her business.
Apologies for the cluttered background. There is a lot going on in our workroom.
The bases were made from old church pews. Roughly 1×6 in nominal size. Warped, but the price was right :-> The uprights are from Home Despot 2×2’s. The arms are Home Despot 1/2″ dowels, I drilled holes for them with a brace and a 1/2″ bit. When the lead screw on the bit began to poke through on the far side I stopped drilling, so the depth of the hole is about one inch.
The balls on the ends are from our local Michael’s. I bought a pack of 18 for $3.00. I split two of them before figuring out how to drill out the 1/2″ holes. Good thing I only needed 16 :-> There was a 3/16″ hole through them. I enlarged it on one side for the 1/2″ dowels. Filling the other side with 3/16″ dowels was the obvious answer. Unfortunately, I did not have any such dowels, However, I did have some 1/4″ dowels. These I cut into suitable lengths, tapered in a pencil sharpener, then glued in place (With some persuasion from a mallet). After the glue dried I cut away the excess with a fine toothed Japanese hand saw.
The arms are not glued in placed, so they can be pulled out for transport. Similarly, the uprights can be pulled out of the bases.
