Thanks. Will work out nice as I had some 1/2" left over from the minimum purchse pre-cut panel size purchased for the internal bracing.
Incidently, when I did a search for "grill" trying to avoid the question, there was another thread where you gave a link to the .pdf file for the grill. While I didn't need it, I noticed that the link is now inactive. Probably happened with the restrcturing of the web site. Just wanted to give you a heads up.
