	Funding: Supported by NSF award DMR-0807731 Precise dumbbell fabrication is a critical step in the manufacture of multi-cell SRF cavities. The resonant frequency of each individual half-cell can be determined by perturbing the welded dumbbell and measuring the TM010 0- and pi-mode. A correction to previously derived formulae for pi-mode frequency of each individual half-cell is presented and compared to SLANS simulations. The RF fixture and data acquisition hardware were designed and validated during 7-cell cavity fabrication. The system comprised of a mechanical press, a network analyzer, a load cell, and custom LabVIEW and MATLAB script.
