I added helicoils to a bowtie cavity, the piezo bases, and the mirror deformation bases. I also tapped the piezo bases and the mirror deformation bases with SM1 threads. I fully assembled a bowtie cavity as a fit check. Future steps: Add helicoils to the remaining bowtie cavities. Test the static mirror deformation. Purchasing required for bowtie cavities: Indium wire/foil 1 in Mirrors Piezos are currently being shipped 06/06/2023 Added helicoils to remaining bowtie cavities For some reason, one of the piezo bases had 3 through holes with too small a diameter. I reached out to Hubs to get a refund on that part. I can drill out the holes by ~4 thou so that the screws fit. Other than this issue, I was able to successfully fit check everything. I also successfully stacked two bowties on top of each other.
