After Jim locked down the ISI, we installed temporary TMS telescope alignment stabilization tooling (D1100613) so we can work conveniently without shaking things too much.

We replaced four out-of-spec washers in TMS seismic safety stop structure (D1001781) with the right ones so that conical washers can be oriented in the specified directions (which didn't change the floppiness of the structure that much).

We also replaced two class-B pear shaped links for the restraint chain with the class-A ones.

Tomorrow, SUS will align ETMX to compensate the PIT angle caused by the weight of the ETM first contact.

They will also pull first contact from ERM and two viewports but not from ETM.

Then ISC will start injecting laser into the chamber.
