ramp plans

[Ex_Rider43]

do you have any ramp plans.. we want to build one out of steel by the guys in the welding class at school but they need a clear plan...

between 5 and 6 feet high...

a ramp like muff's old ramp ( the Z400 jumping )

thanks for any help

[jtej]

you want it 5-6 feet tall....how long, pitch, width, material used? I can draw up some simple plans on autocad with dimensions and all. Where can i see this pic of muff's ramp?

right here :D sit back and enjoy

my friend who made it never had any plans...but make it wider than what we did :p

[Ex_Rider43]

yeah I think it would send us the right height i think.

hey muff how was the ramp? was it kicking you enough to do some good tricks or it it more like a distance jump???

thanks jtej that would be really helpful!! and yeah thats the ramp I was talking about if you could make a simple draw with autocad it would be perfect!!

thanks a lot

[muff]

actually it kicked to much...it needed to be longer. Like if you had it at 40ft, instead of jumping the ramp you were slamming into it which gets real sketchy. I would suggest making it longer and wider, this way you'll have a good transition and it'll flow good.

I have a question for anybody that wants to take a stab at it.
How do you calculate the height and distance you will get off a jump? I know it has to have the speed,height of the ramp,pitch and maybe length. Just something I've always wanted to know. Thanks

Oooops!
Sorry ex-rider.....I didn't mean to hi-jack the thread.:(

[jtej]

Ok so before i go to far a few questions.

~You want the sides and back of the ramp sloped similar to the ramp in the pics or do you want vertical sides?
~How wide is that ramp? Would 6 ft be wide enough?
~What type of material was that ramp made of? What material (size, shape) are you planning on using?
~what were the basic dimensions of that ramp? Would 5 ft tall by 6 feet wide and 10-12 ft long do the trick?
~and anything else you can think of to help me get this ramp just the way you want it.

Thanks
Jonesy

here is a quick 5 minute sketch to give you a couple ideas of pitch Tell me which one you like better (red or blue) or something else

The basic dimensions for this ramp are 5 ft tall and 10ft long

[muff]

you want it atleast 2.5 times longer than it is high...if not you'll just be slamming into the ramp, the tranny wouldnt be smooth enough

i use to have this little wooden ramp, 4' high and 8' long, but you wouldnt want to hit it anymore than low third or youd bottom your shocks just goin off the thing :eek2:

blue

[jtej]

some more quick sketches

it is now 5ft tall and 15 ft long

the one with bracing has a 3 ft brace on the back side so the total length is now 18 ft.

[muff]

I would use that last plan....except add like 3 more vertical supports

[jtej]

yeah i was going to redesign the supports anyways. that was done is 5 minutes, for the final version i will sit down and figure out the best config. for the supports.

Thanks for the input.

muff I dont think the last one would be good for tricks:confused:

I dont know it looks like it wouls send us further than higher???


how about the first sketch with the red and blue lines???

I think the red would be good.. the blue is too steep I think

muff what was the best lenght for your ramp???

we want to have a 40 feet jump bye the way. 6 feet wide and we'll be using steel .

thanks guys this is helping us.

[jtej]

your best bet would prolly be to built the basic L shape then take some string and see what looks good. Take some measurements then start cutting and welding. You can use my stuff as a basic design but it will be up to you in the end.

Give me a couple days and i will have a couple versions done and then you can pick the one you like best and i'll send the dimensions to you.

yea....its just the first sketch if you put it at 40ft you'll be slamming into the ramp...for the height it is at it wont be smooth enough, and as you get better you'll want to move it back and go bigger, but you'll be limited to much by the ramp. The pics of the one I posted we ended up sellin, we just couldnt go any bigger without it getting dangerous.

In the first one the top part of the red one is good, but you need a smother tranny right at the beginning...so like take the first 4 feet of the blue one and stick it on the front of the red one...If i were you guys i'd go for around 12ft long, this should work out pretty well. It should allow for a good 40ft jump and even a little further if you decided to step it up a little more

[Jason1]

the green one looks the best yet. the black one is a big no.. the red isnt anything great at all.. blue and green are the only two real options but like i said greens best.

also.. the extra triangle part on the back really isnt needed, doesnt hurt but is extra work and weight.

also making a bunch of criss crosses between braces isnt needed either but also doesnt hurt. if you use 2x2 14 awg its not going anyway.

you want it safe and sturdy but also easy cheap and light. 2x2 14 awg will achieve that

yea blue or green..either will be nice...i think the black was just showin the triangle :(

another quick one

You dont really need "plans" you just need to know how long, tall, and wide YOU want it. Like us, we just figured 8 feet tall, and said well since were making this thing HUGE, we mide as well go 8 feet wide also. Then we got some 20 foot tubbing for the bottom.(Which ended up being about right) Then we just hooked the string to the top, and hung it down where we wanted it. It worked really well, that way you can see the curve best. It is working GREAT for us. Just do that. If you want a 6 ft tall ramp go between 13-16 feet long, just use the string, get ur angel, and measure how far it is to the end...;)

[Ex_Rider43]

hmmm this last one is looking good but maybe if it kicks us higher a bit..

[HiperEX]

i just made a real nice ramp plan , made the front veiw,side view and a 45 degree angle view, if i could only get it on here would somone post it for me if i sent it to you on email?

see this guys got it here... ramp building isnt rocket science but its not easy either, its like anything else if you know how to do it its not bad, some things are important and some dont. hes doing the important things right, such as the string, just make it as tall as you want, do the string thing like he says and where it touches down to the top of your material is how long, if you dont feel its long enough then make it tall or tame out your angle.. its simple as that.


thats for finding angles, the rest of it all has to do with strength,, proper size for material, wall thickness, bracing. things of this nature. i think hes got that covered too, sometimes people get one thing right but not the other and some people are WAY off and dont get either

[ramp rida 55]

i dont see the point in builing a 5ft ramp because in a few months youll want an 8 footer just build an 8'high ramp and set it at a small gap untill you get used to it:cool:

[EXJUMPER]

Or build the 5' ramp and get used to it and when you decide to step up to the 8' ramp, you could sell the 5' ramp and use the money to fund for the better 8' ramp that you now know how to build correctly. JMO

[Jason1]

ooo now that right there i dont like

[Ex_Rider43]

yeah it look like it will bottom out the bike right at the middle of the ramp. the tranny is not smooth enough I think:confused:

same here...in the beginning it looks like it goes up and then comes back down....you want the slope to be increasing the entire time

15ft long would be a distance jump for a 5' ramp...but with that ramp design its an attempt to be a kicker ramp but it wouldnt flow at all

[HiperEX]

chill out its just an idea

yea but if no one says anything someone will end up building it and wasting $3-400 and a ton of time on a ramp that they dont like or could have been better

Thanks man! Its not as hard as I though, and we are making a SWEET ramp, and its not that hard, but we ARE making ramps for other people too, so if ur interested just give me a holler!;)

We awernt going to use tubing, but thats all we had, and it is VERY strong, and looks very good! We just make a lot of gussets. Prolly wouldnt even have to, but it helps a LOT! I will get a lot of pics for you guys to preview what a ramp is like from LRI!:D

[Ex_Rider43]

ok so jtej where are you now with the plans?

go to my site in my sig... that might explain things for ya


also, i would strongly recommend X bracing over gussets




hyperEX... who in the world was gettin all rowdy for you to say to chill out ? you have to say something like that said or someone might do it
