Soliciting feedback on metal stand for corner install

[afinpdx]

Hello—
I’m planning for an outdoor corner install of a Casa2G90 stove. After much consideration of masonry vs. metal stand, I decided to try to design a metal stand. I’m not a metalworker, though I am a woodworker with friends who weld. At least they are friends for now.

So I put together a design and I’m hoping to get some feedback from the forum. I know there are quite a few people out there who have built their own metal stands and I’d appreciate any advice you might have.

A few notes about the materials:

• The uprights are 3”x3” steel tube (1/4” thickness)
• The rails are 2”x2” steel tube (1/4” thickness)
• The braces on the top are 1 ¼ “x1 ¼” steel tube (1/8” thickness)

This was also a chance for me to learn to use Google SketchUp for doing 3D renderings. For free software…it’s pretty darn cool.

Thanks for your help,
