Materials

• The arm that extends the stand into the front seat will be constructed out of two threaded 1/2-inch steel pipes. The first pipe needs to be cut so that it is long enough extend horizontally from the box mount to where you want the vertical piece to connect to the laptop mount. The vertical piece needs to be cut to the height you want the laptop to be positioned. This is usually about 18 inches. You will also need a 1/2-inch steel flange, two 90-degree 1/2-inch steel elbows, a 1/2-inch steel end cap, some half-inch washers, a 1-inch or larger washer, some 1/2-inch rubber O-rings and some half-inch bolts. To build the stand, you need an old TV stand with two pivoting arms. For the base, you will need enough 1/2-inch plywood and two-by-fours to construct a box that will fit in the rear passenger's foot well.
  
  

Construction

• Construct a box out of 1/2-inch plywood and two-by-fours that fits snugly into the rear passenger's side foot well. Install the flange in the box toward the driver's seat corner and attach one of the elbow pieces to the flange so that the unused end is facing the front of the vehicle. Attach the horizontal pipe to the elbow. Attach the second elbow to the end of the horizontal piece so that the unused end is pointing up, and attach the vertical pipe to the elbow. The horizontal pipe should run between your console and the passenger's seat, and the vertical pipe should stick up around 18 inches. For added stability, you can place a piece of two-by-four beneath the horizontal pipe.
  
  Place the TV stand on the vertical pipe and mark how far down on the pipe it rests. Drill a hole through the pipe at this mark, place a bolt through the pipe and secure the bolt in place with a nut and washers. Slide a few O-rings over the pipe and down to the bolt. These will serve to hold the TV mount in place and to keep it from swiveling. Slide the TV stand over the vertical pipe and push it down over the O-rings to the bolt. Place a large washer and nut over the top of the pipe to secure the TV stand in place so that it does not bounce.
