- 1). Draw up plans for your mini ramp. Most mini ramps are about 8 feet wide, 3 to 3.5 feet high, and 24 feet long. Gather enough materials to accommodate the ramp size.
- 2). Use a pencil, a 2-by-4 cut to 8 feet long, drill and a sheet of 3/4-inch plywood to draw one side of the ramp. On one end of the 2-by-4, drill a hole about the diameter of a pencil (about 3/8 of an inch). Measure from the hole the length of the transition. On an 8-foot wide mini ramp, a 6 or 7 foot transition is best. Lay the 2-by-4 over a sheet of plywood with the untouched end lining up with the corner of the plywood. Drill the untouched side of the 2-by-4 into the plywood so it won't move. Then, stick a pencil into the hole of the 2-by-4 and push that end of the 2-by-4 across the plywood so it pivots and draws the perfect transition circumference on the plywood.
- 3). Following the pencil line, cut out the side with a jigsaw, then trace it with a pencil on three other sheets of 3/4-inch plywood, and cut out three more identical side transitions.
- 4). Connect two sides by screwing them into opposite ends of the 8-foot 2-by-4s. Use several 2-by-4s laying vertically across the bottom, back and transition. Do the same with the other two sides and you will have two halves of the ramp in skeleton form.
- 5). Create a flat bottom by screwing together four 2-by-4s of 8 feet each to form a square. Fill in the square by screwing in extra 2-by-4s to act as support.
- 6). Connect the two halves of the ramp by screwing them on opposite sides of the flat bottom.
- 7). Use the leftover 3-by-4 plywood to create two platforms 8 feet in length and about 2 feet wide. Drill an extra 2-by-4 across each top backside of the transitions so that they stick out from the top of the ramp, then lay the platform across the top of that 2-by-4 and screw them together.
- 8). Stand up a 2-by-4 on each back corner of the two platforms. This step requires using a circular saw to cut the 2-by-4s to the proper height. Screw the back of the platforms onto the 2-by-4s so the platforms stand by themselves. You can then use other 2-by-4s to support the platform.
- 9). Take a steel pipe and lay it across the top of the transition, so it backs up to the bottom of the platform. Use the metal drill bit to screw the pipe into the wood. Repeat this step on the other transition.

Lay the 3/8-inch plywood pieces on the body of the ramp, screwing them into the sides and support beams. Do this until all the support beams are covered. Your ramp is now ready to skate.
