Assemble the Elevator Mast Vertical Tube with an aluminum tube plug and appropriate plastic tube plug sleeve. The tube plug can be installed using #10-32 x 3/8”L bolts.
Repeat this step for both Elevator Mast Vertical Tubes.
Bolt the assembled vertical tubes for the mast to the Elevator Base Tube. The bottom face of the tube should be drilled to 3/8”, providing adequate clearance so the #10-32 x 3/8”L bolts can be installed inside the tube.
Attach the Elevator Mast Cross Tube to the Elevator Mast Vertical Tubes using four #10-32 bolts and 2” long spacers. While the tube can be lower, it is recommended to mount it as high as possible to increase the strength of the elevator mast.
Drill the holes marked in green on one of the Centered Bearing Plates to be clearance for #10-32. Once that is done, press the 1/2" Rounded Hex Bearings into both plates. Install both plates as shown in the image below using two #10-32 x 1-1/2"L bolts.
