Got the vacuum chamber installed on the cart this week:
Here is a shot from the footage with Arash and Kashish helping:
I might also have a supplier lined up for the “L” gasket that has to be replaced on the bottom side but I am still getting quotes. For the rest of this week, I plan to finish lathing the wood mold and then building the plastic mock-up. The good news is that the cavity might not be as sensitive to the diameter of the narrow end as I thought. If the diameter is not 170mm, then it means the frequency of the TE0,1,n mode will need to be adjusted with the tuning plate to bring it back to resonate at 2.45Mhz, although, in talks with Kevin, it may affect matching.
