the "Start"

[mr fish]

major progress in the "reducing the amount of pedal strokes top to bottom project"......:thumb: well done everyone,Ben,Graham,sime,Tom,Matt,Dave,Will,Ken,
James and of course our new friend the truelly mental "Rob the Canadian" who carried not one but two(sneaky as he was told not to)6x6 by 6metres long posts :wooot: :nono: :wooot: on his back up the hill,...........nutter :D also thanks to "James Kendal Trees" for there very valuable lift with the timber and for starting the carving stuff

and what a monster it is too, hopefully sime will have the 'first attempt' picture aswell which resembled a full size rugby post more than anything! ending sunday night we managed to get the bulk of the frame work up and the decking across the top, aswell as important bracing and most importantly of all the hand rails.

a productive weekend, i am sure everyone who helped out will agree.

watch out!

even in this blurred shot you can see how awesome the starts going to be :yeah:

[Baker]

You lot did well good this weekend the new start tower looks well professional

[dave_mawe]

It looks tall and feels taller when your up it. The first attempt would have been totally insane

[matt]

the first attempt would have got you loads of speed. but what you did on sunday look's awsome. when the roll in is finished, the unfit people like myself won't be knackered before the first berm, which will be good.:thumb: :thumb: :D :D :cool:

[dave_mawe]

All the hill needs next is a proper uplift.:D :D

[Chris C]

Looks ace even now!

[Carldeenio]

Ah man, the craftmenship is awesum. U guys really know how to build. Really sorry i wasn't there...

[jack]

looks totally bonza! sorry i havnt been around lately, loadsa school stuff to do, seems to be easing up a bit though, so hopefully after this week (internal 6thform exams) i should be around to help.

[mr fish]

a slightly clearer shot :D

[mr fish]

ok all you budding mathematicians whats the perfect angle,in building terms 45 degrees has some good things going for it ;)
maybe Dr Nimul can help :?

[dave_mawe]

the higher the angle the more speed it should give you but if you go to steep, the angle at the bottom might slow u down as the front wheel hits the ground it wont be smooth. A dirt transition would sort it out though, maitain your speed and make it smoother to ride. 45 degrees is the number most commonly used when building anything really.

[True Saxon]

45° distributes any load most efectively. If its steeper, it wont necessarily be faster, as the slope length also comes into the equation.
I think that instead of working to an angle, we should decide how long we want it and just build it regardless of angle. I dont think we need to worry about optimum angle as whatever i think it will give plenty of speed.
If you really want to know the optimum, i'll need the exact height of the platform and to keep things simple keep it on the same base level (although it isnt level in reality).

[jack]

speed has to be gained over distance, therefore 45deg. wouldnt necessarily be the right angle. even if it was a more shallow angle, with a longer slope then you would gain alot of speed.

Isnt that exactly what i said?
And as the angle decreases, slope length increases.

Take a look at the quick sketches.
To me 45º looks ay steep.
30º looks spot on.

Also, with a quick model of my bike (wheelbase and bb height) it would ground the chain ring if it was 45º

[Ben]

absolutly 30 (looks round the key board for degree sign) looks just right some thing you can pedal down aswell but something that isnt so steep most of your speed is soaked up in the change of the dangle :thumb:

[dave_mawe]

Can't veiw the attachment:? says i dont have permsiion but it sounds right.

[dave_mawe]

Did it get finished today? I was going to come down for a few hours in the afternoon but kickoff was delayed and i didn't get home till 2.

[Baker]

It was really good. There were quite a few people there but it was quite slick on the tracks

start tower,now with added m10x250 coach bolts fitted in important places:devil:

[Baker]

So is it ready to ride

[mr fish]

some progress was made today,thanks to Ken,James,Will and Dave for there help etc :D sorry about the quality of the pics but you get the idea :devil: http://www.trailblazerz.net/images/mr_fish/start tower1.jpg

[Carldeenio]

looks really good, its gonna rock when its done. Nice work guys...:wow:

[Will]

Its awsome, you get loads opf speed off it, either going into the burm for the shore or the technickle DH. Brill

[mr fish]

OH YEEEEEEERRRRRSSSSSSSS :warning: :fu: :warning: :fu: :warning: :bana:


http://www.trailblazerz.net/images/mr_fish/start tower rs1.jpg

looking nice and steep

http://www.trailblazerz.net/images/mr_fish/start tower16 rs.jpg

a few more tweeks and your gonna fly down the hill from this mutha :devil: well done everyone who came today it was well worth it !:devil:

[fragy]

it looks the dogs cohuna's some top new year effort put in their. If the work that you have all done over the last couple of days is the bench mark for effort and quality in 06. we best be getting ready to host the nationals :O)

[Carldeenio]

One word 'wowsers'. that looks like loadsa fun. Whats the transition like though, from ramp to ground? Does it loose any speed or is it super flowing???

[dave_mawe]

It needs a dirt transition we were just using a couple of bits of wood. but when the first berm for the flowshow is changed it'll be awesome

[Carldeenio]

i hear the starts finished, looking forward to some piccies being posted...

[Will]

Nearly finished

[jack]

the start slope is huge, the pictures really dont do it justice!

[Baker]

It is well fast it really gets you going. Just need a better burm onto flowshow then it'll be awsome!!

[mr fish]

as some will know there's been some building going on near the start,namely a steep to right hand turn chute thing off the right hand side of the start tower followed by a rolling double(i'm sure there's a name for it) :D a big thanks to all the folk who helped (in all sorts of ways ;) ) cheers Fish :devil:

[dave_mawe]

How big is the new double, could i clear it? bearing in mind i had managed to get down the steep roll in. And how did the meeting with the inspector man go?

[Will]

Looks neat! lots of work done on Sunday then!?!?

[matt]

i haven't been up in ages because of my bottom braket has broke.But you have been busy the second part of the roll in looks awsome can't wait to ride it.

[Baker]

I dont know how people will clear the new double bearing in mind that ben was just getting it but that was in wet and he had lost a bit of confidence i think due to falling/slipping out saturday i think. it is a good enough launch i think. Just go for it mate. I think i will soon.

[dave_mawe]

That was rather funny on saturday. Kinda put me of the new roll down though because ben messed up on it

[Kenny B]

Really looking forward to having a go on this bit, I was there Sunday but my bike's not ready yet.
PS absolutely knackered, I wouldn't want to work for Fish in real life!!!

[mr fish]

today was ace :D i spent most of the afternoon sessioning the top section......very nice and a beautiful day as well ;) the new double is well cool altho i havn't cleared it i'm not to far off :eek: it also is very good to get a manuel going ;)

[Baker]

Sweet i can't wate till the weekend n trying out some of the new stuff!

[Ben]

No rain last night but a really harsh frost, should have cleared up this afternoon though, if it stays like this the weekend should be great!

[jack]

i've looked at the pics now im back on my own pc and it looks (to quote nathan barley) "well weapon" i really cant wait to give it a go. the double looks pretty 4x and very fun!
