After reviewing and researching this project I found that it was rather expensive for the average layman to make this free project. All the aluminum parts makes it rather cost prohibitive.
So I decided to look into seeing if I could build it in a more cost effective way.
For the slides I am using 2 - 24" miter slides without pre-drilled holes (cost about $20.00) drilled holes using my CNC machine which seemed to work very well in both instances!
Cross Support Members I am using 2" by 4" at present --- but may be re-thinking this due to appearance!
Have feet which I had taken off of several tables that I had purchased from Rockler.com which were replaced with wheels. I will be using these feet for the bottom.
I will post photos of my finished version of the standing desk here when it is completed.
Approximate total cost to make $70.00
