Using the line making template mark 2 lines around the end of the shaft pole. repeat on both sides.

Place one wheel in the middle of the shaft.

To secure the spring to the wheel you will need: 3 washers, 1 bolt and 1 nut.

With the 4 sheet doors, you will need to add a bracket to stop the wheel from breaking under the weight.

With 4 sheet roller doors, you'll need to add a bracket and an additional bolt and nut, to the top hole of the wheel. No washers needed for the outside.

The bottom bolt will still require its washers as usual, but the top one will not need a washer.

Place 1 washer on the bolt, then put the bolt through the wheel, place another washer on the bolt. Place the long end of the spring on the bolt, then put on the last washer and nut. Repeat on the other outside wheel.

Using the spanner and the drill, tighten the nut.

Move the shaft to the lip of the table, making sure the lip of all three wheels are flush with the lip of the table, then clamp the outer wheels to the table.

Unclamp one wheel and move it along with the spring to the first black line, then clamp the wheel to the table again, repeat on the other side.

Attach the spring clamp to the other end of the spring and tighten using the drill. Repeat on the other side.

Once the spider is in place, pull the spider, along with the wheel, to the second black line, tighten with your hands and then, with the ratchet. Re-clamp the wheel to the table again.
