Assembling The Frame

Step 1: Buy Parts

Buy two sheets of 3/4inch (18mm) plywood, two red bricks, and three 10 foot 2x4s. The dimensions of these parts are not critical. We understand that the weight of bricks and dimensions of lumber can very significantly from one part of the world to another so we've done our best to create a design which works with those constraints.

Step 2: Collect Tools

To assemble your machine you will need a Philips screwdriver, a saw capable of cutting a 2x4, and a pair of pliers. A power drill is nice, but not necessary.

Step 3: Set aside parts we don't need now

Set aside one sheet of plywood, one 10' 2x4, and both bricks. We will need these parts later, but for now they are in the way.

Step 4: Cut 2x4s

Cut the two 10' 2x4s to the correct length segments. From your two 2x4s you will need to make pieces of the following lengths.

Number Needed	Length (cm)	Length Inches
2	26.5	10.4
2	63.5	25
2	146.5	57.75
2	41.25	16.25
2	~27.0	~10.5

None of these lengths is a critical dimension. The design does not rely on the ends of the cuts being perfectly square. The dimensions of the piece left at the end of cutting are particularly non-critical.

These pieces will form the legs of the machine like this:

We recommend cutting both ten foot 2x4s like this:

Step 5: Get the 3 Hardware Bags

You will need the parts in these bags.

Step 6: Create temporary motor mounting points

Attach the approximately 10.5 inch (27cm) pieces left from the cutting process to the upper corners of the plywood using the provided short wood screws. If you have access to a drill, drilling pilot holes for the screws can help prevent the wood from splitting.

Step 7: Attach the motor bracket

Attach the motor brackets to the 2x4s in the upper corners of the sheet of plywood using the wood screws provided. The front of the bracket should be flush with the sheet of plywood.
