Discussed with Matt about locations in the Tower that can have heat leaks. The tower bottom part have multiple stages which can have heat leaks. One quick way to check this is to look for electrical shorts between those stages. But Matt recalls having some electrical shorts between some stages inherently (still need to look for documentation about this).

Next steps will be to start assembling the stages after removing the copper tapes as required.
