Hyper9 Motor Support and Cradle - Version 1

Purchased a Stainless Steel motor cradle from NetGain Motors (part MC-H9225 for $112.50).

The pair of galvanized steel clamping bolts are 3.5" long and 1/2"-13 coarse thread (3/4" socket head).   Stainless Steel replacement bolts for $3.13 each are available from McMaster-Carr ( https://www.mcmaster.com/93190A726/ ).

DSC01366 Closer view of 1/2" bolt assembly of the cradle.  The bottom of the cradle uses a pair of steel narrow-base weld nuts, 1/2"-13 thread size  (McMaster 90594A033, 25 units for $22.27).  It is important to align the bolts correctly to engage the lower threads and not cross thread them..  The top fitting is just a thick washer that is crimped fit to the top of the cradle (no threads).
