Ok, beaming tests was as I remember.

we would have a chassis bolted to the floor at the rear via the shocker mounts (now this varies as to the engineers as were as to hold the chassis down) now if my shocker mount are say 10" away from centre and then you test the same chassis with the shockers are 15" away from centre, the test will have different results.

One engineer didn’t require the chassis to be bolted via the shocker mounts some did it via the frame???

As for the front of the car, if you were to place a jack stand under the front of the centre cross member and as he does the beam test, if the stand has a 1 1/2" plate then you are not getting a true reading.
As well as if the material you use is say 100x50 SHS to do the twist test, some engineers require that the material should be factored in but others do it as a solid beam.
Also what is the method that was used by the said engineer to carry out the beam test, how many dial gaugers were used, and at what point did they place them, now we only had two dial gaugers, so we could only take two readings at one time and then move the gaugers again to take another reading.
now after going thru 6 engineers over the past 15 years they all have there own way of doing the test, BUT they all said that the other engineers way of doing, either the calculation or the way the test was done was a ???.

One car was built to go to qld, it was engineered in Vic and when it got to qld the guy got the car to a roller, called a local engineer and the engineer pulled the car up as the body was about 1-2 mm to thin, it should have been 6mm.

Now we had a hell of a fight and the customer had to (if I remember correctly) put extra layers to please the engineer.

Nearly all the engineers we used have left because of thousands of other people trying to do the same thing....build there dream.
It’s the d1ck heads at Canberra, and the guy behind the counter that has turned this whole industry up side down.
My worst fear is that in about 2-3 years time the only kit/replicar industry will be gone.

It will cheaper for a guy to buy a second hand car, and re-design the whole thing to suit him.
