Hay Xion, I am glad you found your way home.

I do understand the challenges of trying to fab something at home or even at a workshop for that matter and trying to get it Bang On! is no simple task.

I have seen how you where going to mount the drives, and if I am right there on a angle that is conected to the self below.
So if I am right, then the challenge is getting the shelf square?

Do you have any photo of how you are conecting your shelf?

I have lots of ideas to try and help but I would only be wasting your time until I know how you intend to mount the shelf and if it is in fact the shelf the is the real challenge.

I know you set out to do as much as you could by your self, (not commercial fabricaters) so let me know if I can help, PM me if you feel this is best.

Hang in there champ
