Torch,
I was using the stand for keyboard and the upper for my 17” laptop.

Problem? It blocked part of my audience. I cut about 25% of the post. The top of the post now supported the back end of the laptop. I built side supports to keep the laptop from tilting and tie downs so it was secure.

Since I decided to use my IPad I took off all the supports and screwed an IPad support on to the post. Love doing this stuff.
Why am I using my Ipad? Just had eye surgery and my eyes are now 20/20 right eye and 20/25 left. The IPad screen is now big enough.
