I went back into BSC8 this morning to fix the ISI's weight problem. Ended up bolting 7 of SUS's dog clamps at various points around the optical table, mostly around the top of the quad. I tried to be careful to not to pinch any cables or interfere with any moving parts. We may not be exactly back to where we were ~2 months ago, but everything is back into spec, or at least as close as we can get. IAS is in now taking final measurements.
