How do you keep the bolt from turning when adjusting the plastic knob?Nice use of some nice wood and tools, but I'm not crazy about the design.I would have; rounded the corners of the columneliminated the 5" square and counter-sunk the bottom of the column to conceal the bearing

In the time you used to write your comment, you could have shaken an egg...

Instead of the dowel and string, just put the end of the nail in the drill you used in step 4.

This is incomplete! How far from the center of the 'crank' is the bolt for the connecting arm? How far from the pivot bolt of the can holder is the bolt for that end of the connecting arm?!?!

Determining how it's not working needs to be step 1.

All to vague to be of any use

You should have labeled each end of each cable since you can't see where they go when they go thru the peg board. You need to know what they are to know where they need to be connected.The 'side' pieces aren't needed with most TV stands / media centers.Your last picture shows that you painted the visible side of the pegboard - that's not in your steps.

Don't the vent screen and the vent hole need to be aligned? Your hole seems off-center while your screen is centered.Unless I'm only doing one - I think it'd be faster to have a template for the hole(s).

Misleading titleShould be: cupholders for a flat surface with empty space behind it. And how do you know the space behind it is empty?

I LUV this! I don't need a laptop tray, I need a phone and notepad holder.Instead of the elbow right above the cup holder, I"ll use a T and a 2-3" adapter as a cup holder.

You have omitted the instructions - admitting it is not an instructable.I'm here for build/make instructions, not use video.

Where are the instructions? This is INSTRUCTables, not VIDEOables.

Where are the instructions for making this?!? A video of using something is not what I consider an instructable.
