You can make it to your own preferences .. it's just as an example for how it could look, you can always mak it high if you want.

you probably want it longer than 8ft. mines 12 and its perfect. ive had 6ft and 8ft ones and they arent fun. you can really grind them.

"yeah it only took me 20 for ALL of the wood and angle iron. but the problem was, it was too high and it took like 3 of us to get it in my garage. just too big in general.

so today i modified it. i made it 15in high instead of 30. it slides AMAZING. i tought some kid how to grind today on it. and i put wheels on the side of it with stoppers so i can ride it like that too.

i think 20 would be alright too. idk if its too high its not really fun to learn on. im sorry but i really dont want to learn how to smith to 180 on a 35in ledge.

tht ledge is fun a slides like butta

i got a question... if im doing 2x4 supports every foot why do i need such thick wood... couldnt i go down to atleast 1/2 inch wood instead of 3/4. that would save alot on wood.

Then your deck won't be as stable. Maybey you want to do like manual 180 on the box .. then its better to use the thikker wood.

should have kept it at 30 abod

nah i agree with you there... but even 1/2 is really solid when you got 2x4 braces every foot... i think you could save some wood and do every foot and half with 3/4

yea i had a 9 ft ledge up on my pyramid funbox, 18 inches high, it was fun, but it was too quick, you definately want 12' or more.

Im thinkin about puttin a 2 ft high 40 ft long ledge between my 8 ft quarter and the 5 ft flybox.
We have enough coping, it's gonna be so much fun.

if you guys do1/2 or 3/4 inch wood on anything BMX related, im gonna slap you bitches. 2x4's are just as cheap as any size smaller then that. You dont NEED 2x4 supports every foot, unless you plan on having a fucking elephant using it as a circus platform. You can go every 2 to 2.5ft if you want. If you used a 2x8 or 2x10 under the coping side, you could just have one support in the middle, that is if you want that shit to bounce around when you land on it.

When i make a grind ledge, i always use a 2x10 underneath the grind side of the box, makes it solid. Then supports about every 2 to 3 feet is good enough. I've been doin this for about 3 or 4 years, never had a problem.

okay thanks man thats what i was wondering.... casue im seeing a few typos in there lol...

it does say to get a 4x4 sheet of plywood... idk where to get that lol.


so i can do every 2 feet with the 1/2inch... im only going 2 feet wide.

wow im an idiot, when you said thick wood, i thought you were referencing to the 2x4's. I take it you meant the PLYWOOD. I use half inch plywood on everything. I double layer the ramps, but only single for grind ledges. Keep in mind, you're gonna be beating on that ledge alot, so you wont be doing too much on the deck itself, just mainly the steel. I would definately put a decking support ever 12 to 18 inches with half inch. You dont have to put as many legs on it tho. As far as legs go, every 2 to 3 ft (24 to 36).

well im not planing on folowing the specs on here .

i dont think it will last with that setup. its using the plywood as a side support.

thanks for the help i will post up pictures when its done
