Step 2: Prepping the box for Pinball playing field
Materials Needed For Step 2:
* 2 - 2"x2" Lumber 8' Long
* 1 5/8" Coarse Drywall Screws
* 2'x4' 3/4" Birch Plywood
Cutting and Building the resting platform:
First cut two 2"x2" 37" long and two 2"x2" 23 7/8" long. Next measure 12 1/2" from the bottom of the back wall up. Now draw a line across the back wall. From the line you just drawn measure down 3/4" and mark three spots that a screw will be screwed into. Now drill a pilot hole in each mark and counter sink the holes on the outside of the box. Next take one 2"x2" 23 7/8" long and make sure the top of the lumber is placed on the line. Next screw it together from the out side.
Next take the other 23 7/8" long 2"x2" and place it on top of the front wall support. This is where it will be mounted. Draw a line across the top of the 2"x2" lumber onto the front wall support. From the line you just drawn measure down 3/4" and mark three spots that a screw will be screwed into. Now drill a pilot hole in each mark and counter sink the holes on the outside of the box. Next take one 2"x2" 23 7/8" long and make sure the top of the lumber is placed on the line. Next screw it together from the out side.
Now you will need to draw a line on the side wall. Take a caulk line and put one end to the back wall mark and the other end to the line on the front wall and snap it. Follow this step on the other side wall. This will be the angle of your pinball playing field board. A typical pinball machine playing field will have a 6%-7% playing field. Before moving on place the 2'x4' birch plywood into the box. Then go under the table and make sure that your lines on the side walls match the bottom of the birch plywood. If everything is good then take the plywood off. Once you are done making sure that the line is right then measure 3/4" down from the line and pilot drill four holes make sure that you leave at least a 8" space between the front 2"x2" and this 2"x2". You need to leave room for the flipper mechanism underneath the play field. Once you have figured this out then mount the 2"x2"x37" long to the side wall. Once done follow the same instructions on the other side.
Cutting the Hole for the Flipper Levers:
You should still have the line drawn on the side walls for the playing field supports. This will be the top of the hole that you will cut. We will be cutting out a rectangle shape. With the line being the top of the rectangle we need to measure 2 3/4" from the back of the front wall. This will be the front of the hole that we will have. Now measure 1 1/4" more and that will be the end of the rectangle. Now measure 7/8" down from the top line. Once all of the marks are made connect the dots and then you have your self a rectangle to cut out. Use a 3/8" drill bit and drill a hole close to one corner and another hole on the opposite corner. Next use your jigsaw and cut out the hole. Once your done with one side follow the same instructions on the other side.
