ausie comp ramps

[mulisha_mike]

i have been lookin for basic designs of ramps and i like the way an ausie comp ramp looks like the one in the picture i will post on once i find it. any ways i know the basice stuf like th the height, the lenght and constant radius in meters, :( but i live in the US and i dont know how to use meteric measurements so if some one could post the measurements in feet and inches that would be awsome:p
thanks

[mulisha_mike]

heres the pic of what i kinda want it to look like, i just want the constant radius, length and height in feet and inches if any one can help
thanks:D

[Mungoman45]

Length = 6.1mtrs = 610cm = (237.9 Inches) = (19.78 Feet)
Height = 2.6mtrs = 260cm = (101.4 Inches) = (8.43 Feet)
Width = 1.2mtrs = 120cm = ( 46.8 Inches) = (3.89 Feet)
Radius = 9.1mtrs = 910cm = (354.9 Inches) = (29.51 Feet)

Thats roughly the measurements in Inches and Feet :D But if ya wanna work it out more exactly:

1 centimeter = 0.032808399 feet
1 centimeter = 0.393700787 inches
1 meter = 3.2808399 feet

[GStylEr]

Hmm a 260ft high ramp would be interesting lol, I think your calculator may have broken man :p Oh well he's got the ratios now he can work it out for himself hopefully hehe.

[Mungoman45]

Hehe yeah, not to mention 120 feet wide LOL thanx for pickin that up man, i was in kinda a rush and wrote the CM measurements in where the feet measurements were meant to go, Tizz all fixed now, should look a bit more in proportion :p

[mulisha_mike]

thanks mungo
i was wonderin does any one know what kind of kick do these ramps give ya and whats the biggest gap their good for
thanks

[kyle]

30ft high kick at 80 ft

[Robbo66]

not to sure about 30ft high at 80ft..

[troop of doom]

yea me neighter

[robson]

i would have thought that aus comp ramps could go further than 80feet. ????

[GStylEr]

Yeah comp ramps can go to around 110 if you're crazy ass, haven't heard any bigger than that so... 80ft would throw about 35-37ft high I'm thinking so yeah. They're good kick, seems pretty easy to move on the bike although I haven't jumped many other ramps only a few different ones.

[mulisha_mike]

I know this is a stupid question but I havnt hit to many ramps and I plan to eventually move the ramp out to 80 feet and where im gonna put it i have limited space i have a little thin area where i can get plenty of rum but where I'm gonna put the down ramp thers a fence sorta neer there how much room will i need to slow down when i land so i dont put it to close to the fence or to far away and waste room
thanks:)

Can i come riding at your place as I'd be guaranteed some drinks later :p Let the Rum flow my good man!:D

Anyway, it all depends on your level of riding as to how much room u want for the run-out off the downramp. My mate likes to land and then he's on the brake and stops about 5 metres past the bottom of the downramp. He also doesn't have much tire left :D haha!
I'd say a good 15 - 20 metres between the bottom of downramp to fence, and then i'd put a berm next to the fence if you for some reason have any problems stopping, just hit the berm and get the hell outta there.
Also you gotta think about if you actually jump to far and flatland you won't be thinkin about braking, you'll be thinkin if you've snapped ur legs in half, then probably head straight into the fence and do more damage. In other words, leave as much room as possible.
Good luck and i'm sure we'd all love to see some pics when you get it up and running

[mulisha_mike]

yea it would be a bad idea to have it too close seing the fence is barb wire and right on the other side of it the ditch goes right up onto a highway.
I wont have it set up till like june cause all the ground here is frozen and I have to wait till summer break from school so i can spend a few days on the down ramp.

I wish I had plenty of rum but theres a alchol law here in the US got to be 21 and I'm only 15.:( :D

[GStylEr]

Is there a reason you can't have the jump running the opposite way? So the fence is at your runup end? That would be a bit easier and safer to setup if you could do that but I dunno if that's an option for ya.

[mulisha_mike]

I dont know if thats an option, but i dont think it is. on the side opsite of the fence there is allot of stuff and i only have like a 5 foot wide run way to gain speed i think, i havnt looked at the place latley cause its covered in like 2 feet of snow and i cant take my peice of shit snomobile out there cause its way to rough right now

[Gropey]

my setup is really tight and once you come out of the berm its 60 foot to the ramp, 60 foot gap and after the landing ramp about the same. i wanna pull mine back too one day so i hafta get rid of the berm before the ramp making the runup longer.
ive seen someoje else say once runup=gap=other bit lol
so if u wanted to jump 80 foot youd have a runup that long and the distance from the downramp to the berm or the fence 80 foot aswell

[Mungoman45]

I cant be 100% sure on this, so dont quote me, but i "Think" i recal Cam tellin me ya only need 20ft runup for a 70ft gap on a 250....

[Gropey]

faarrrk that haha
but that does make sense when ya see the size of runups indoors, for like 65 foot it is tiny runup so woot woot

[FrEe_ RiDiNg]

that ramp looks sick im jus getting the dimensions for it now

[kyle]

umm.... weres the credit, for my pic,:p lol

[mulisha_mike]

ok, forgot to say in the origonal post to give kyle credit for the ramp i just kinda pulled the pic of another post

[mulisha_fmx]

whos ramp is that ?

[mulisha_mike]

I dont know its a pic that i guess its a pic that kyle posted, but im not sure if its his or somthing he just found. How bout an answer kyle?

[mulisha_fmx]

how many metres to a aussie comp ramp ???

[mulisha_fmx]

like how many metres of metal do i need ???????

[mulisha_mike]

that all depends on how much support you put in.

[mulisha_mike]

well I'm gonna be ording metal soon, but I'm still not sure on the design. I have been drawing them up but this will be my first ramp and i have no idea how much supports in and where is the best spots. if any body has some good plans it would be nice. but the main reason i want plans it to know how much metal to order.

[GStylEr]

We ordered 80m (10 x 8m lengths) plus the 2 x 8m rolled transition pieces. We used 7 of the lengths and have 3 left over. This is how it came out.

[bakflip_kimble]

that looks F#@king nice, beautiful job fellas

[bbeeuuhh]

yeah nice ramp ;)

[fmx_kid89]

nice ramp !!!!!!!!!!!

[mulisha_mike]

thanks gstyler, i'll just order the metal abd build the frame and then add supports

[GStylEr]

Thanks everyone, it's so beautiful to hit...

[mika]

hey mulisha mike grab ya calculator and if ya wanna go from imperial to metric just multiply ya inches by 25.4 to get millimetres and divide ya metric by 25.4 to get inches.(eg 2 inches times 25.4 equals 50.8 mm) know how ya feel bro had to convert all the measurements from distlers site

[mulisha_mike]

i made up some plans by modifying the ausie comp plans a little

i want to post them up but i cant put them into a jpeg or any thing and my scanner isnt working

[mulisha_mike]

sicnce i cant post a pic heres the dimensions

length:20 feet
height: 8 feet 6 inches (8.5 feet)
CR.: 29 feet and 7/8 inch

if any body has a way for me to post em tell me

[ChAgAp]

Very nice.... I want one.

[mulisha_mike]

got a scanner with a new computer so heres the plans i have had folded up for a while, sorry about the quality if you can even see it

kinda used some of the paper for some scratch paper

[mulisha_mike]

ok it came bigger then i thouhgt, but its easier to see, and i know some of the measurements are a little off, but i drew it up real fast like the whole thing in a half hour

[mulishatroop]

hey does anyone have full plans for the aussie comp ramp in metric units? and by full i mean including all mesurements and angles. If i made it id downscale it by about a 3rd and have it about 1.7m. Thanks alot if you can help me.

[mulisha_mike]

i think i drew some up on that same program, i will put the measurements on em and post em up soon as possible

[robson]

hey i am building my aus comp ramp at the moment. and i am basically doing it off that pic with dimensions that is on the first page of this forum. I was just wondering... with the upright supports that are 0.43m and 1.45m high--> is that from the base to the surface or is that the length of that piece that supports it. coz i have used it as the support length... it isnt a huge issue, i will just have a higher ramp, but i was just wondering still....

[twitch fan]

hey how much metal do u need for the transition before it is rolled like wen its jus straight

[Mungoman45]

660cm (6.6mtrs) Pre Rolled
675.3cm (6.75mtrs) Rolled

......Roughly ;)

Best way to go about it is to get em to roll 2, 7mtr lengths, just to be sure ya gunna have enough....or, by the time it comes to build, if you wanna tighten the radius, make it into a kicker, you'll have 25cm to play with.

[twitch fan]

nice i was told 8mtrs cause its a 9.1mtr radius

[Mungoman45]

9.1mtr constant radius doesn't refer directly to the length of the steel, or the length of the curve.

[twitch fan]

yea but could i use a 8mtr length

[Mungoman45]

Ya can use whatever length ya want, but remember the whole length will be rolled, and the leftover end bits...which will be like 2 meters worth of steel, wont be any good for use anywhere else on the ramp cause they'll be bent.

My suggestion is to buy your steel in 8 meter lengths, and cut the ends off BEFORE rolling, that way you can reuse the offcuts. But as i said, i wouldn't cut it perfectly to those lengths i gave above, as that's exact measurement, and doesn't take blade width into account and errors and what not, so best to cut 1mtr off the 8mtr lengths and which will leave you with 2, 1mtr lengths you can reuse and still leave you with around a rullers length of error room, or as i said, if you decided to make it more "poppy" you can tighten, or "pull down" the curve.

[twitch fan]

thanks

[CR_NZFreestyler]

hey g styler ur pic of ur ramp u made from the plans of kyles right? if so the transition that u rdie wat gap do u put each cross strut is it 1/2m gap for all of them and how many do u need also wud u be able 2 tell me the measurements for where 2 put the supports thanks
scott-o

[GStylEr]

Hey dude nah I didn't use Kyle's plans there, I used the original ones that were in Freerider and adapted the support design to what we thought would be good and a bit lighter. If I remember right the cross supports we used were 2ft between each, or around there, 400mm is the number that comes to mind so I think that was it... And yeah all the same distance between each other. What you can do to work out your own, is once you have the transition welded to the L frame and maybe a few supports in there, you can then measure the length of your transition piece, and divide that by the number of cross supports you'd like to put in. That will tell you how far apart to put them and they will all be evenly spaced.

Sorry I can't tell you more it was a fair while ago we built it and it's not actually here at home right now or I'd go check how many there is for you. Hopefully I've helped a little bit and if you need any more info just ask, my ramp will be coming back this weekend so I can check specifics then if needed.

yes but mungo u must realize not all of us are pros an like to risk it like cam does......

oh btw that ramp i beleive is on eof "mcnormoo" mick norman....
heres my ramp if u want to see it...same as grants, just with a verandah..pic below ;)

[HILLIER]

yer i stuffed up above..but here it is...

[CR_NZFreestyler]

thanks rhys how come they leveled it off at the top? woudln't make any difference wud it? and grant wen u get ur ramp bak if u cud i wud appreciate u looking and seeing how many cross struts u have got much appreciated thankyou

[deev8]

If i did up some plans on cad would any want to pay anything for them? i can draw up some good simple ones of the standard comp ramp like above and sell em pretty cheap, or if u want your own custom ones you could give me some rough sizes and i could work em up for u for a slightly higher price? i dont know, just an idea if anyone was interested...
but hey, if i find the time and you want me to go all out and make some killa ones with cut off list sizes (and even prices if u wanna go that far) then i could do that maybe but itll cost yas?
just a thought

[GStylEr]

Yeah no worries dude. Here's a pic that kinda shows how many it's got, but I think the bottom section might have a different amount cause of the way the ply sits so I'll still check that for ya, but from this I can see that the top 2 sections have 5 supports each...

Hone'n' in on my racket aye chief.... ;)....not that there is much of a "racket" to speak of, as most people wont admit to needing plans, let alone pay for em.

And yes, Rhys, Cam is a pro ;), so it's probably not too much of a risk for him. Obviously the longer the runup, the more comfortable ya gunna be, depending on your skill :) but the more skilled you get, and know the capabilities of both yourself and your bike, the more you can push it,and the less room you need to bugger around with. Especially in comps, as you only get a certain time limit on your run, the more time you spend in the air, rather than on the runup, the better ;).

[CR_NZFreestyler]

thanks grant! half way up the transition the support for it is that 2 40 by 40 by 2.5 miol thick piecies or is it thicker steel?

[GStylEr]

The ramp splits into 3 pieces, at the end of each piece of plywood, so yeah it's 2x 40's cause they bolt together, you can see it again down further with the shorter uprights, same setup. With the uprights they just bolt together with one at the top and one at the bottom, so there's only 8 bolts all up and it holds sweet.

[deev8]

meh just an idea, oh well, everyone seems to be into sharing all their sizes and construction methods which is cool as

[CR_NZFreestyler]

how come u made ur ramp in 3 pieces isn't it easier 2 make it as "one" ?? wat do u reccommned i do ? this is really great and i really appreciate this Grant.

[Mungoman45]

splitting ramps is just for transport purposes as it's easier to fit on a trailor or ute in 3 littler pieces, rather than one giant ass, heavy ramp. Sooooooo pretty much up to you how ya make it, gotta decide how much ya gunna be shifting it.

[GStylEr]

Yep exactly what Brad said. If I had that thing in 1 piece I'd be, um, very screwed at this point I guess, I don't have a big trailer at all and so I have to have it split to take it anywhere for demo's, which is where the ramp is right now since I got a demo to ride tomorrow. You still make it in 1 piece you can split it whenever you want just about, we made it as 1 then chopped it up with the appropriate supports before putting the ply on.

So as for what you should do Scott, it's a matter of, is your ramp going to be getting transported at all? If it's not and it's just gonna sit at your compound all the time then you may as well not bother splitting it... But if you plan on taking it to other places, for demo's or otherwise, I'd recommend sectioning it. If things change and you still have the same ramp in the future, you can still split it without a great deal of hassle I would imagine so either way you'll be fine.

[CR_NZFreestyler]

ok thanks for that Graant and goodluck for tomorrow !

[GStylEr]

Thanks dude, it was today and it rained a fair bit and was really windy but it finally cleared enough for 1 demo and I managed pretty good considering the weather... Anyway I checked that support thing for ya, as I had suspected, the 2 biggest pieces have 5 cross supports each, and the smallest one has 4, because the ply/surface runs long past the transition so a 5th one isn't necessary, the surface just hangs over and transitions to the ground. So that's a total of 14 to save ya the maths. :p

[CR_NZFreestyler]

good 2 hear Grant and thanks for the info wud u bve able 2 measure where abouts along the bottom of the ramp where the supports link to the transition? cheers scott-o

[GStylEr]

Well unfortunately I'm a very tired and lazy person haha, but I can tell ya where they connect to the actual transition piece if that helps at all... Every 800mm. That's not including the smallest section's upright bolt together supports though since they were put in afterwards. We just worked out the angle so the longest support was at 90degrees to the transition I think, then kept them all the same so it looked good. Except for that first support in the small section, it's just upright cause it's really short anyway.

[CR_NZFreestyler]

Is this correct Grant.
Thanks Scott

[CR_NZFreestyler]

the picture would help !
