Forums DIY and Mods Backyard mini-ramp help and beta Viewing 14 posts - 1 through 14 (of 14 total) Author Posts April 25, 2007 at 10:24 pm #568831 bcrider 4149 Posts I’m looking to build a backyard mini-ramp for the kids and I was wondering if anyone had any beta for me. The space we’d like to put it will allow for a 12′ wide ramp and I was think of using a 4-5ft tranny. Also wondering if any norcal peeps with ramp building experience can lend a hand? TIA! 🙂 April 25, 2007 at 10:58 pm #596237 shasta 143 Posts Been awhile since I built one but I do remember a key to a good transition/radius was to cut the radius into 2 sheets of plywood for either side, nail in verticle studs then 2×4’s horizontally to join the sidea at each vert stud. After that its easy to layer plywood sheets for the ramp surface. Thin plywood flexes easy for the ramp surface you just have to replace the top sheets every so often when they wear through. What a great dad, mine just grumbled because the homeowners assn hated the plethora of surf groms in the neighborhood.

The key question is how tall are you buidling it? Mine was 4′ tall x 12′ wide. It had 8′ flat and 7′ transitions (radius). You either loved it or hated it because it was fast and got fairly steep at the coping. My buddy had one of the same dimensions but with an 8′ tranny. I thought it was too slow but easy to ride since it didn’t get as near vert as mine. 7.5′ tranny might be ideal. You need at least 2 layers of 1/2″ plywood as a skating surface but more is better. Mine was uncovered all year long in PA winters and held up for 2 years before I had to start patching holes in the plywood. I remember trying to pre-bend the plywood by elevating the ends, weighting the middle with some logs and watering the sheets with a hose for a few days before it would fit tight against the 2×4 on the transitions. If you can afford to, use 2x6s (or alternate them with 2x4s) to keep the skating surface solid and less like a trampoline.

The best site (which you’ve probably already been to) that I found was http://rampplans.org/ Tons of good, free, and varied info on the art that is ramp building.

I would be sure to brace the diagnoly horizontaly and verticly to prevent wracking. I would also consider masonite for the top sheet in luei of plywood. Good luck. May 3, 2007 at 12:33 am #596243 48steps 39 Posts I was reminiscing yesterday about some of the backyard ramps we built back in the day…they were 95% total crap. Some people have pointed out the easiest way to build a wack ramp and that is to screw up the trannies. If it is for the kids, bigger is probably better. If you go with big transitions, consider a 4′ wide extension on one side of the ramp. It’ll be nice for learning to drop-in and getting confidence with lip tricks. Anywhichway, you rule for hooking the kids up! Oh yeah, get a nice length of chain and lock to keep any neighbor kids from poaching the goods. May 3, 2007 at 1:27 pm #596244 affix snow 521 Posts Sooooooo cool! Oh the memories! Ill echo what everyone has already said, but would recommend actually using a transit and sinking several 4×4 posts into the ground as the ramps foundation (concrete recommended). This serves several purposes. 1) the ramp will be SOLID!!!! No movin that sucker! 2) it will be off the ground and wont rot out the base. 3) How cool will you look using a transit!? 😀 Seriously. Friends and i made sveral a ramp and they all were a little “shaky” cause they were jsut sitting on the ground and eventually the bases would rot out. I’d go 4′ high, 8′ tranny, and 8′ flat. If your kids outgrow that, you get to build a bigger ramp!!!!! May 4, 2007 at 10:08 pm #596245 Yoda 264 Posts Check out Freshpark – http://www.freshpark.com/ I met these guys at ASR. Very cool crew from the Bay area. I might be able to get you a deal. You might contact them about halfpipe options… they had one at the show. Big bennifits over building your own! May 7, 2007 at 8:22 pm #596246 bcrider 4149 Posts thanks for the input everyone! 8) here’s a couple of pics of what I had in mind. I’ll take a pic of the area in my backyard that I have to work with tonight. May 7, 2007 at 8:42 pm #596247 mtnrider 740 Posts Sickness, perfect size…I want to come over. pppleeaaasssse.

We would hit our heads whenever you stood up when grinding. To this day I bend the knees alot on my 5.0’s Consider metal too, I always loved metal cause it makes reverts really smooth, oh wait, it might get hot in that cali sun.. I would have been so psyched if my folks built me a mini when I was a kid! I would probably be a better skateboarder and gone pro at 12 then ended up with a drug habit and some bad ass tattoos. (at least that’s what my parents thought would happen) Viewing 14 posts - 1 through 14 (of 14 total) You must be logged in to reply to this topic.
