Soapbox tech

I beg your pardon? I've no idea what this is about, but it ain't nothing to do with moderation ...

[campbell]

Fergus. You poke fun at me. I laugh along with your joke. I poke fun at myself too. And you react like that?

Re-read it. You misunderstood. Big time.

[woody]

Lol. Careful. You have not seen my backup plan

Careful ? . . . feck off . . . you gonna ban me ?

I've seen your tech skills first hand dude, you need a designer, fabricator and a driver . . .

Discussion over, the SE moderation sh*t brigade strike again . . .

Fd

At a total loss as to how you came up with that reply?

Chill out Fergus and leave the Magic Mushrooms alone, that is not the FD that I know.

HOW did that escalate!?

[anthonyyule]

Wheel chair wheels and ply... however read the regs ages ago and seem to remember wheels are restricted to 14".

up to 20" wheels

There are relatively strict rules to stick to for size and footprint.
I will double check but fairly suire the regs stated no string or foot actuated steering.

but advantages are;
Low CoG
long, width is determined by the track we are racing down, so a longer narrow car will be faster (less drag) than a wide car if its just straight lines (think dragster) if its twisty will need some width.
Weight is your friend, heavier cart will accelerate quicker and have a greater terminal velocity than a lighter one in the same conditions. but see above comment on the track.
I have opted for BMW wheels on stub axle with semi slicks, agian dont know what cornering we are expected to do.
front wheel steering
rear wheel braking
Steering - sussed as per previous thread. I also found an old tractor mower which had some really simple pitman type setup, worth a scour of the local garden cente / tip / scrappy. The kids loved that by the way...


That all said and done. I am with Campbell, just making it would be an achievement!

Team 'Duct tape and hope'

Our reg's are pretty relaxed as Im sure you now all have seen

[anthonyyule]

Go here, then down to "Rules and Guidelines" link

Wow, that changes thing! Originally I thought it was going to be official soap box rules. Those are very loose and there's a picture of one with rope steering so happy days.

Now reconsidering entry....

I had no involvement with the choosing of the pictures (rope steering wouldn't be my choice!)...... but feel free to build what you like

[anthonyyule]

The Red Bull stuff certainly planted a seed. But some of it's on a different level entirely and clearly designed for spectator value!

10 points to Campbell. Finally we get to the most important part of the Soapbox Derby. Spectator value.
For sure I'm loving the thread on Soapbox Tech..... But I'm just wondering when you'll all start your next thread on Soapbox Attire.......

Its a themed race remember, and all competitors and team members must dress up

woody in Pink, Dodgy Dave in Tartan etc.

Tony ,

woops. Still, not sure if i can source any free enough.

[Ferg]

Yeah, the wheels are the one bit I reckon I'm just going to have to part with cash for.

[anthonyyule]

if I find that people are really struggling with the wheel size (which is entirely possible because we didn't give the reg's a huge amount of thought when we devised them on the back of a fag packet.....) then I'll be quite happy to increase the size to 26, 27.5 (700cc), 29" - whatever suits.

Too much bother to ask the general public on the Event's FB page.... but if you guys (as techy-guru's) think that it would be easier for everybody then I'm quite happy to issue a clarification to the reg's with a waiver that large wheels can be used.

Thoughts?
