I just recieved the box with everything in it and an autograph from Herrick Kimball wishing me good luck. Now the fun starts. Went to the scrap yard and looked for HDP board, aluminum and stainless steel. Stainless steel is $2.50 a pound!!! I will probably go with the aluminum. They have 3/16 inch 22 x 22 inch plates there for $5 vs $63 for SS. Anybody that has built one and would like to offer tips and suggestions, please bring it.
