So far I'm keeping a cadence regular updates! Back in July of 2021 I ordered a pair of Nuobell adjustable dumbbells, and they've been working great. However, I didn't splurge for the stand when I got them, rationalizing "I've got a woodshop, I can just build one! I don't need to spend $115 plus shipping!" Well, a little over two years of the dumbbells living on the gym-mat floor later, I've actually built one. I planned it out in sketchup to built from cleaned up 2x4 lumber, except the top surface and bottom shelf, which I had large enough scraps of 3/4" plywood to make. Cost of materials was about $15 worth of nicer-grade 2x4x6 lumber from the hardware store, the cross-braces were joined with pocket hole screws, everything else was wood glue and screws. I contemplated painting it, but decided it leave it as it is for now; it might get a second sanding and a coat of paint once it's gotten dinged up living in the gym for a while.
Now, there were a couple of mistakes I got to learn from along the way. I originally measured the two dumbbell cradles side-by-side plus margin as 18" x 22", and imagined them sitting vertically side-by-side, so I could easily pull them off simultaneously. It turns out, (1) I got my dimensions flipped, my stand is wider than it is deep, and (2), at 30 degrees of tilt, there's nothing actually holding the extra plates in place, they just fall down once the dumbbell is removed. Thankfully, these basically cancelled out, I was forced to orient them horizontally, which is the stand I actually built. Looking more closely at the commercial stand I see that the angle is both smaller than I used, and at a compound angle, that is the dumbbells are tilted toward the user and slightly inward.
