[project] The Ultimate Track 205

[davenport 51]

what sort of profile are you trying to bend??? what material??

 

we have a 3meter press brake at work but limited tooling means some returns/bends aren`t possible....

Basically trying to make 50mm x 50mm box with one side missing, so a C-channel basically. Just plain old 16 gauge or 1.5mm mild steel.

 

If you could make me a couple for less than £60 each then the business is yours!

[Rippthrough 98]

Buy a length of 2" box, cut one side off.

Sorted.

 

 

edit: Damn, I should have just said I can do them for £59.99 and cut them myself,

Someone hasn't been reading the thread!

 

That's exactly what I'd done and it warped like a banana!

[wicked 103 3 Cars]

Maybe cool it, when you cut it. When you cut 1.7m at once, you add a lot of heat...

[Cameron 16]

Yeah I think it's that combined with residual stresses from when it's rolled. I can't afford to risk cutting another two parts and having them warp, it would be cheaper for me to fork out for the folded parts than get another 6m length of tube posted.

[Rippthrough 98]

Take the surface skin off all the sides first with a flap disc in a soft pad....might work if you try that with the bits you've done tbh.

[davenport 51]

yup, it`ll warp like a **** if its slit along its length....

 

this 50x50x50 channel you need, is that external measurents??

 

if so i should be able to get 2 bits done by tomorrow night... as for collection, well i`ll be over @ kimbolton (TDF) at the weekend i dare so so can meet you there or @ brampton services on the A1/A14 junction...

[Cameron 16]

I've attached a drawing.

[Leet205 48]

your full name and number is in there...better watch you dont get signed up to cat facts

[davenport 51]

hahahahaha what a massively ott drawing,.... you could have just said external measurements....

 

 

leave it with me i`ll see what i can do tomorrow evening....

[Cameron 16]

Cat facts? Tell me more!

 

I already had the drawing btw.. had to make it for the places to quote me.

[davenport 51]

lol, no worries... i checked next door to where i work and they have some 1.5mm mild steel lurking behind the guillotine...

[Cameron 16]

Win winnity win. I took the attachment down to avoid receiving cat facts, let me know if you need it and I'll email it to you.

[Rippthrough 98]

They don't now!

 

I just checked and my folder isn't quite long enough, would have to make them in 4 pieces.

[Cameron 16]

Yeah that's what I'd have to do too, except I don't have a folder at all so they'd have to be beaten over the edge of my workbench.. not ideal.

[davenport 51]

channels done xx

[Cameron 16]

Nice one!

 

I'm down visiting my brother today, will give you a call tomorrow to sort out picking them up.

[davenport 51]

Not a problem... i may have a favour i need in return!! Haha

3 words that may please Mr Ripthrough: Rear Wheel Drive.

 

1 word that probably won't please anyone: Duratec.

 

1 word that definitely will: Sequential.

very nice liking the sequential idea, on the duratec why make it harder for yourself trying to adapt a peugeot lump when rwd boxes for duratecs are readily available

[Cameron 16]

Exactly the point! Glad someone gets it.

 

RWD gearboxes for Duratecs are commonplace because of the Caterham scene, and if I can't afford sequential there'll still be plenty of good alternatives.

[GeorgeXS 32]

Good news Cameron, what made you change your mind?

[Cameron 16]

Well, it's been bugging me for a while that I'll struggle to mount a FWD engine and gearbox in a way that I'm happy with.. it would either be sitting too high and too far forwards for my liking, or punish driveshafts by running big angles. Also being realistic about the class I want to race in (Sports Libre) no matter how good a FWD car I manage to create it will always be at a disadvantage to the other big builds running rear or 4WD, and I definitely want it to be competitive amongst the big boys.

 

The original idea of mid engine RWD is nice, but a bike engine is either expensive or underpowered (or both) and a car engine takes up too much of the room I'd want to sit in. So front engine RWD is kinda the sensible option, with a dry sump I can have it as low as I want and there's a good choice of gearboxes for Duratec engines. I'd have to get shafts made up for the FWD layout due to my custom suspension, so there's no extra cost really, just a propshaft. The weight distribution will be way easier to manage, too.. basically all signs point to RWD.

You'll be competing in sports libre?
