Steven ,
I thought the gravity load was to include the weight of the part itself. I knew it would not have a significant effect on the result in this case, but included it just to be thorough. Is that not the purpose of the gravity load tool?
I have requested the guys in the shop snap some pictures the next time they use this tool. I don't know when that will be, but I will update this thread as soon as I get them.
Until then , thank you very much for your help.
