I needed to know the angle of the ramps' incline and the length of the incline. I used a block and a piece of 1 x 6 lumber. The 1 x 6 clears the cowling under the front bumper with a little to spare. My old ramps were 8 1/4 inches high where the wheel rested. I would like to duplicate that on these ramps. The base of the incline needs to be about 30 inches long (yellow tape measure).
Step 2: Materials
I bought two 2 x 8 boards twelve feet long and cut them to make four boards six feet long each. I also bought an eight foot board (2 x 8). I cut it to six feet in length. Clamp the boards so the rings are set opposite one another. I also used two smaller pieces of 3/4 inch stock and some long drywall screws (2 1/2 to 3 inches). The high-tech version of these ramps uses a circuit activated by the pressure of the car's wheel to light a small lamp. This tells the driver when the wheel is in the proper position on the ramp.
Step 3: Mark the line for the incline
I measured 15 inches in from each end and marked a straight line between the blue arrows. This marks the incline on the two ramps and gives an incline the proper length according to step 1. Turn the clamped assembly over and make an identical line on the other side. Make certain the lines are parallel to one another and do not cross each other to form an "X".
Step 4: Screw together
Mark the five boards to know their order in the stack. Begin screwing them together with long drywall screws. The line for the incline is between the two blue arrows. The assembly will be sawed apart later. Place the screws so none cross the incline line. You do not want to saw through screws later.
