Build your own nitrogen bottle brackets?

Sorry bout the wait, been mad busy. Here's the bottle holder. This design should work well with a nitro tank, just gotta make it longer. I haven't gotten around to making a clamp to hold down the top yet.        

Very nice piece!! would you be willing to make another for nitrogen tanks? or would you tell us how high it is and what thickness aluminum you used? it looks like 1/2 plate but not sure. Thank you
