  In this paper we consider the Boothby-Wang construction over twist 1 stage 3
Bott orbifolds given in terms of the log pair $(S_{\bf n},\Delta_{\bf m})$. We
give explicit constant scalar curvature (CSC) Sasaki metrics either directly
from CSC K\"ahler orbifold metrics or by using the weighted extremal approach
of Apostolov and Calderbank. The Sasaki 7-manifolds (orbifolds) are finitely
covered by compact simply connected manifolds (orbifolds) with the rational
homology of the 2-fold connected sum of $S^2\times S^5$.
