Wow I just re-read my post and now I am offended at myself. My education seems so low with the communication skill that I presented. It is as if I did not want him to make it himself. My appologies Mr. Miller, and welcome to the forum. Let it be know that the two best "engineers and chemical specialist" frequent this forum. I, on the other hand, just absorb as much info as these gentlemen can give. I introduce to you Fabmandelux, and Phydeaux88.
