seamless?
Another question from holland...
I know your're gonna call me a cheapass and that's ok.. But is it really neccessary to use seamless steel pipes for the wishbones???
I was thinking of using "regular" pipes but of a slightly bigger diameter...
Would that be a problem??
The car is a modified locost by the book, but with IRS...
And I'm going to place a 300HP 400Nm C20LET Vaux in it.. (I know it's ridiculous but "It has to be!"

I've made replacement ones for a Westfield out of some thick walled tube, that was about five years ago, no problems reported since.
DO NOT PUT ON KNOB OR BOLLOCKS!

No, as long as the tubing is sized for the expected load. Remember that larger thin wall tubing is stiffer then smaller thick wall tubing.

people often seem to use 25mm x 2mm wall erw tubing, would the consensus be that this is adequate provided the shock mounting is well thought out?

Where!? 
Normal is getting dressed in clothes that you buy for work and driving through traffic in a
car that you are still paying for - in order to get to the job you need to pay for the clothes
and the car, and the house you leave vacant all day so you can afford to live in it.

MK Wishbones are made of ERW.
I would be happy using 25mm round 1.5mm wall.
Are you a Mac user or a retard?

I have only seen true oval tube on one car, the rest were just partially crushed round
If you can keep you head, whilst all others around you are losing theirs, you are not fully aware of the situation

It's called flat oval Mark. Aero tube is the groovy stuff but damn expensive

Yes, it comes complete with granular areas in the crushed sections

The real issue is most of us have no idea what loads get fed into these tubes. Sure we can work it out for a given cornering force, that's not
hard. The real issue concerns hitting a pothole... just what load does that feed in? How big is the pothole, how deep, how wide? How much air is in
the tires, are the tubes already curved, all of this changes the answer.
Since all we can do is guess, guess on the high side. That is, if you calculate during 1G cornering, a given suspension tube will have 300lbs
compression load, round WAY up for design purposes, like 1500lbs.
I used a "Strength of Materials" book to find column strength of the tubing I was using. I would have used 25mm OD, 1.5mm wall thickness
all around until I found it was too weak for the rear, so those tubes are 32mm OD.

I've been busy again....
We've bought a ford gearbox today..
The bell-housings.. We'll have to modify one to fit both engine and gearbox..
Milling the adaptorplate on my cnc-mill...
Can someone identify that gearbox for
me?? What type is it? MT75?
On the outside it's exactly the same size as a T9... Would it be possible to fit the internals of a T9??

It looks like a T9 to me.
If reverse is push down on the lever and left/forward then it's a T9 otherwise the MT75 has reverse to the right and back.
It doesn't look much like this?

Looking at the speedo drive it comes from acar with an electronic speedo.
Hope that helps
