Another round of alignment, rubbing checks, TFs, rinse, repeat were done today.  We got to the reaction chain positioned in approximately the right location with respect to the main chain in the longitudinal direction and the pitch close enough that the inter-chain bump stops are approximately equidistant.  We decided to stop at this point to run some TFs, which, of course, showed some issues.  We eventually got the main chain free of rubbing and took a full suite of low resolution TFs, enough to tell us that we are healthy and free-swinging.  

For next Monday, we have on the docket to do some cable and ESD checkouts with EE and take a set of fully suspended violin mode measurements.  Then on to fine alignment of both chains.
