Any one had a go at a rocket?

Mr Whippy - 28/3/08 at 10:55 AM

not much to it is there?

quite like the look of it though I notice that their doing the old trick of splapping on a very fancy set of rims to make up for the rest of the car

made a real rocket, a flying one quite good fun really but whoooosh! and it's over

There is a guy on PistonHeads that has

How annoying...I have everything for building that apart from the chassis/plastic, sitting in the garage and a 2ltr Vectra outside (now running fine)

Don't like it myself. Any car where you can see the contact patch of a tyre would seem to be asking for trouble with rain, stones, etc. flicking up.

Imagine being pebble dashed as you travel over that newly laid road!!

Lower down he says he has repositioned the cycle wings further back round the wheels, so that would help. My solution would be lexan sheet down each side - you would still be able to see the chassis tubes, but would be protected somewhat. You could maybe even make a fold at the top to make an arm rest

The chassis looks to me to not have enough tubes or sufficent cross bracing, the front is very open in the area surrounding the wishbone montings.

I like the simplicity, but I too think that it is not that strong.
But then again I like open chassis (although mine will have lexan sides)

I agree about the line-of-sight comments with the contact patch. Nice to look at, bad to drive.

Also, I can't believe the frame is complete. I can't see the front springs/shocks, and there's pretty much zero torsional strength around that area. Flexi-flyer?

The picture at the beginning of the thread is almost the finished article!
If you look at the actual bone mounts of the original car, they actually hang off the side rails with very little triagulation!

Hats off to anyone who produces a car, but I think the chassis need s beefing up around the bone mounts

Second from last picture looked like a painted chassis where the rear wishbone mounts are just tacked on

kb58 - 28/3/08 at 08:01 PM

Good eye, and you're right!

I am assured by our highly qualified structural engineer that it would take a force in excess of 4 tons to rip a bracket off the Rocket chassis. The Rocket has 30 of them. However it would take only 2 tons to rip a 12mm bolt through the side of a 3mm suspension bracket on most cars. The chassis has been designed by calculation, not over engineered or over weight.
The high levels of torsional rigidty are acheived by design and the use of large 50mm tube with a 2mm wall.
Some of our customers do take an unpainted chassis so they can weld components on to suit different engine options.
