ETM03 PUM in oven.
As of 4:30 this afternoon, Gerardo and Gerardo Jr. were in the process of loading the replacement PUM into the airbake oven, the last step needed before use in a monolithic suspension. Tomorrow morning it can go to an end station for welding. Knock on wood. Well done powering thru placing 2 prisms and 4 magnet mounts, cure times included, in 2 days, guys.
Note, heat was not actually applied to the PUM until ~8pm that evening, with temp achieving ~32 degC (shy of nominal 34degC) around 9-10pm. Soak time set to 6 hours.
