Centerline were drawn on the mounting/bearing block and bulkheads, and holes drilled for mounting the blocks. It was necessary to sand a slight bevel onto the forward face of the forward blocks to ensure "squareness" of the torque tube in the blocks due to the bevel at station 3. This in turn would lead to the mounting hardware not exiting the station squarely, so a beveled hardwood block was fabricated for the forward side of the station to recieve the washers and nuts squarely.
