Consistent with most, my aluminium bed that came with my Power Spec 3D pro is warped. I would like to replace it with a 1/8" sheet of Borosilicate glass but information seemed to be scattered across forums. If you've done the installation, can you please review the following and let me know if I'm missing something?

Mcmaster_Carr 1/8" (3.2mm) 6"x9" sheet of Borosilicate glass (PN: 8476K74)
Z-axis shim I plan to use: http://www.thingiverse.com/thing:515065
corner cilps I plan to use (open to a different model for 3mm): http://www.thingiverse.com/thing:546851

I believe I read that some people avoid using clips by using a silicon sheet beneath the glass above the aluminum. Anyone have comments on this?

Thanks for the help.
