A good mini ramp is something that almost every skateboarder, BMXer, etc. wishes they had in their back yard. Well now you can build one on your own with these instructions. The dimensions for this ramp are: 6' high, 16' wide, 6' deck',12' transition, 8' curve radius. Since there are so many cut lengths to make, each one has a reference number that I will be referring to during the instructions.
What You'll Need
- Forty-six 4'x 8' sheets of 3/8" plywood
- Eight 4'x 8' sheet of 3/4" plywood
- Five 12' 4x4's
- One hundred and forty-two 8' 2x4's
- ninety-five 2x6's
- two 16" black steel pipes
- six hooked bolts (3/8") with nuts and washers
- something to cut the pieces with
- A pencil to mark your cuts
- Deck screws and a drill
- One tape measure
- The required safety gear

Cut the side pieces (2x)
You will need 8 of these for the whole ramp so it is best to build them all at once. You will be able to get one side per sheet of 1/2" plywood (#2.1) Since each side is made of 2 pieces, it is difficult to continue the curve onto the second piece. To make this easier you should line 2 sheets of plywood up to create one 8' x 8' square. On this you will draw your curve so that half of the curve is on one sheet, and half is on the other. Remember to use a string and pencil (sting=length of curve radius) to make a perfect curve.
Start framing
In order for the two sides to stand up as one, attach these 5 2x4's (#4.2 and #4.3) and one 2x6 (#5.1) first. The top two 2x4's will be explained in the next step.
Join the two sides
Use two overlapping 2x4's so that the coping (pipe) has something to sit in. After the 2x4's are attached, roughly cut a square notch from the plywood using the 2x4's as a guide.
frame the table
Since each 2x4 (#4.2) is spanning a length of approximately 8 feet, it is crucial that you space them close together (every 6"). use the 3" deck screws (two in each stud) to hold them in place.
Begin work on the ledge
After you've made two curves you can place them side by side and start of the deck. The deck we're making will be 6-feet deep so there will be plenty of space for standees. Use 2x6's (#5.2 and #5.3) for the deck, and 4x4's (#6.1) for each corner post. You can then use 2x4's to join them all on the bottom.
Add more cross pieces
Use your 2x6's (#5.4) to frame the deck, spacing each stud approximately 10-11" apart. Feel free to space them closer if you want.
Add another layer of 2x4's
The transition will be made up of 2x6's spaced approximately 8" apart. (You can use 2x4's for this if you space them 6").
Screw on the first layer of plywood
This part is simple, screw on the 3/8" plywood starting from the top of the slope, moving towards the transition. When you get to the second layer make sure you don't line up your joins in the same spot as the first. You should always try to have some overlap. Also, it is crucial to have every join line up on a stud so there is something to screw it to. If it doesn't line up with one, you can always add another stud by climbing underneath the ramp.

how long is it all together
@tomtom298: It is about 40 feet long.
is there a downloadable version of this that has all the measurements?
@profus Sorry, we don't do any blueprints or anything. You will just have to use the information on this page for your reference.
~Gregory
can you tell me how long the flat bottom is? or a length that you would recommend?
cheers
@profus: The flat bottom is 12' long, which I recommend for bmx riding on a 6' ramp. Although if you're short on space you might still be able to get away with an 8' flat.
@gSchier, thanks for the info.
ride on
@Profus No problem!
could u put plans for a 10'-15' vert ramp please
and a mini mega/big-air ramp
Where does the Masonite go ?
@Supersatio It goes on as the third layer of plywood. It's just not shown here.
hello i m building a mini ramp with spine in the middle is 7 ft tall ,with radius 7ft. and the spine is 6ft tall with the radius 7ft, i want ur advice and how u think is gonna work on that way..thanks
could you give me the measurements of plywood i would need to make this ramp 12' wide with a wooden backboard on one side please.
how much would it cost if you had an 8foot flat?
Hello,
It may have been asked before but would you share your SketchUp plan (*.skp) for the 6' Mini Ramp? I would like to modify it for my available space and apply all the dimensions I need. Thanks very much and I appreciate the info on the site.

@laverda_jota: I will see if I still have the original files somewhere, and if I do, I will post them all :)
Thanks for that! It would help with the first step ... now to figure out a 4 season solution! Please login(right side) or Register to leave a comment.
