The sprockets are lined up and the frame is marked where the mounting holes for the pillow block bearings will go.
The mounting holes are drilled and threaded into the frame.
Both of the bearings are bolted in place.
The jack shaft is slid into the bearings and the sprocket is set back on the shaft.
I haven't cut the keyway for the sprocket into the end of the shaft yet.
After I get the sprocket on the other end set up and the shaft cut off to the correct length, then I'll cut the keyways in both ends.
