Sorry Matt, must have misunderstood what you told me (i did have a look at your site and though £2k for a chassis with your FIA cage was in the ball
park according to your prices on there). I think the Aries one comes in at a bit under £800 too. Adjust the figures slightly but the point still
stands. 
From what i recall that point was: you gets what you pay for.

Back to the original topic and not petty mud slinging....
...does anybody have any relevant CAD files for Locost/Aries cars?
I'm starting to work on my designs now that my CAD box is up and running again.

I don't think that there are many (if any at all) about in the public domain. There are some drawings about (Locost, not Aries) but they are
generally available as pdfs.
Good luck with your project.

Hi
There are no real Cad drawings for an Aries chassis. And a book locost chassis is not the same as the Aries as the chassis uprights where moved to
gain better geometry and chassis bracket positioning.
Cheers Matt

Ooooh, i'm curious where they were moved too now (And if i can have another excuse for slowing down my build by having to move mine!)

Hi
Lol i wouldn't wory too much Mike I just moved the top front frame back and the uprights around to enable the brackets to sit better on the
prototype chassis. Gave the required castor and more room for the mounting of an anti roll bar behind the rad.
Cheers Matt

Bloody Hell!....as somebody who was considering a aries build....where the hell do i go from here? If its true these chassis are not
straight.............are they all crap?.wesfield,gbs zero,mk, etc.
I work in engineering and use micrometers,verniers, an tape measure,doesnt anybody else??? oh and a spirit level,god help us!

No they are not crap. It's all a matter of degree.
If you are really concerned about getting the last mm of accuracy then you need to build your own.
As some day it may happen that a victim must be found,
I've got a little list-- I've got a little list

Oh its degrees as well as millimeters is it? ......My only welding skills are using a arc welder and i dont think that qualifys. so its okay to have
atwisted chassis then? I always thought if you built a jig and cut everything correctly,and Tack welded initially,allowing for distortion etc you
wouldnt be far out......or am i being nieve......10\15mm seems a bit much.

I'm curious how far out my home build chassis is - perhaps in a year or two when i get on the road i'll find out (once i've been to
procomp).
Will give me a nice winter upgrade (Which will take 2 or 3 years). For road cars don't stress too much - as matt says, its the kit he prefers
out of the others.
(had a drink or three - just pointing out in case i've miss quote matt)

No im only playing to the gallery, im only looking for a fast road tourer+ occasional blat on some airstrip,but it did come as a bit of a surprise to
how much some chassis were out

I thought one of the advantages of use brazing rather than MIG welding is it can be easier to produce a dimensionally accurate tube chassis, as less
heat distortion, ease of tacking and making complex joints, as well as the ability to repair. Also a brazed chassis should have less welding stress
built in (and in theory such welded, not brazed, structures need heat treating to remove it). Do need accurate close gaps in joints for brazing
though.
Apart from ease of using MIG, the cost of kit and what Champion's book suggests, I've wondered why all Locost chassis are all welded not
brazed? This is unlike all Lotus and Caterham 7s made by Arch Motors (until recent metric chassis made by Caged on a computerised welding jig) as well
as Mallocks and other steel tubed racing cars, including homebuilt 750 Formula cars. Maybe cheaper for Locost chassis manfucturers to use MIG?
Is the art of brazing is lost, and no-one wants a live flame or exciting gases in their garage?
Cheers
Mike
