Peter, I'm sorry but that would require sharing more details of our design than I would like to share. I hope you understand.
Cheers,
Jarek
Yes Jarek, I understand.
So, to you and to Theophile, if you are both suggesting that the customer locate the center of gravity of his component and then place that in proximity to the center of gravity of the isolation platform/device but the customer is not told where that is or how to locate it, how would you suggest the customer proceed in order to achieve optimal performance of your product?
Is this what you meant earlier when you wrote to just place the component's COG in proximity, which would mean directly above, the geometric center of the top plate of your Stacore? If so, then that can be determined following Theophile's suggestion with the half round dowels and simply locating the center of your platform by noting the intersection of two straight lines.
I will try to discuss this with Kinetic Systems, the manufacturer of Vibraplane.
EDIT: It also seems to me that placing a component on the standard Stacore is considerably different that placing it on the Advanced Model Stacore because of the change in load distribution because of the three ball/cup assemblies. In the latter case, the load of that top slate shelf plus component is distributed directly over the three pneumatic footers while in the standard model platform, the load is distributed over the entire surface of the platform's top plate and differently distributed to each of the pneumatic footers. I would think that is why placement of those three ball/cup assemblies is so critical.
