2nd Stage
The images below show the assembled 2nd Stage. The number of stages you plan on assembling will affect the final appearance of your 1st Stage.
Step 1
Before assembling the 1st Stage Horizontal Tubes, drill the threaded holes on the Aluminum Tube Plugs that are marked in green. Both sides must be drilled. Then, assemble both 1st Stage Horizontal Tubes as shown in the image below.
The bolt heads for both Pulley Blocks must be facing towards each other.
Step 2
Bolt the 1st Stage Vertical Tubes to the assembled 1st Stage Horizontal Tubes. The top holes in the vertical tube must be drilled clearance for #10-32 bolts with the outside face drilled to 3/8", similar to how the Elevator Base Tube is done. When assembled, the heads of the #10-32 x 3/8"L bolts will sit inside the 1st Stage Vertical Tube.
Make sure to install the Bearing Blocks with only one of the 3/4" OD Radial Bearings on the back of the mast.
Step 3
Mount both Chain Attachment Brackets to the bottom 1st Stage Horizontal Tube in the orientation shown below. The brackets will be installed using six #10-32 x 2-1/2"L bolts and #10-32 nuts.
This step is only required if you are assembling a 2 Stage Elevator. If you are assembling an elevator with 3 or more stages, these brackets must be mounted to the 1st stage after the Elevator Mast.
