The first measurements of tensor observables in $$\pi \vec{d}$$ scattering experiments were performed in the mid-80's at TRIUMF, and later at SIN/PSI. The full suite of tensor observables accessible in $$\pi \vec{d}$$ elastic scattering were measured: $$T_{20}$$, $$T_{21}$$, and $$T_{22}$$. The vector analyzing power $$iT_{11}$$ was also measured. These results led to a better understanding of the three-body theory used to describe this reaction. %Some measurements were also made in the absorption and breakup channels. A direct measurement of the target tensor polarization was also made independent of the usual NMR techniques by exploiting the (nearly) model-independent result for the tensor analyzing power at 90$$^\circ _{cm}$$ in the $$\pi \vec{d} \rightarrow 2p$$ reaction. This method was also used to check efforts to enhance the tensor polarization by RF burning of the NMR spectrum. A brief description of the methods developed to measure and analyze these experiments is provided.
