If anyone is interested in the rivet pattern,
I took a photo of the pattern I have and put it up on my server at
http://www.priveye.com/images/RIVET1.JPG
I used 6x32 S/S button heads. The heads are the same diameter as those of the 1/8th in. rivets. Allen key size is 5/64ths, available in lengths 1/4in., 3/8ths, 1/2, 5/8ths, 3/4, and 1 inch.
I used Totally Stainless in Pa.. 1 800 767 4781....... Rd.# 1 Box 1219 Brodbecks Pa. 17329
