So we sat down and looked at some commercially available ramps, and got some ideas for size. Then we sketched some construction ideas and came up with a plan.
We went to the local home supply store and picked up a sheet of 3/8" plywood, a 2X4X10 and a box of 2" screws. As we don't have a truck, and the ramp was going to be 2 feet wide, we had them cut the plywood sheet lengthwise. This gave us two sheets of 2'x8' plywood. This is more than enough to make two ramps with scraps left over. Also, I ripped the 2x4 in half (for the support cross beams) on my table saw. You can do the same, or you can use 2X4. Our supplies were about $17 (a real bargain, eh?).
The project shouldn't take more than 4 to 5 hours to complete. I used my table saw, jig saw, and drill. You can use a circular saw as well, just remember to use a guide and cut really straight.
Please wear a helmet when using the ramp. Also, be aware of your ability or the abilities of your child. This ramp was designed for a ten yr old for recreational use. If you are bigger or want to hit it harder I recommend using thicker plywood for your vertical supports.
So what do you need?
3/8" plywood sheet
Table or Circular Saw
Drill and bits for pilot holes and driving screws..
So, here is the result. Enjoy.
Does it work? Sure check out the video.
Step 1: Cross Beam Supports
These will support the ramp deck, and lock the vertical supports together.
I started with a 2X4X10 that I ripped in half (lengthwise) on my table saw. This gave me a cross beam that was roughly 1 1/2 x 1 1/2. You can do the same, or use the full 2X4.
Cut them to a length of 24".
In addition, you will need one more support beam that is 23" long. This will go on the back bottom edge.
