Whats not adding up right here?
 

Putting down the base rails. I'm not getting the same measurements near the front end as the book says. I've checked my marking out 100000 times and that all matches but br1 and 8 are different. Br1 approx 990mm and br8 approx 820mm. Has anyone else had this trouble? Should I just cut them to fit?

isn,t BR8 & BR9 the 2 rails that are the base of the engine bay? sorry, not got my book at home,

basically BR8 & BR9 come to a point at a junction with BR1 & BR2...

cheers

Yep thats them mate. Just I make BR1+2 shorter by about 3mm and BR8+9 almost 30mm longer then the book says.

but if you make BR8 & 9 longer then you,ll be causing a prob for BR7 which U1 & 2 sit on which need to be in the correct place as the rearmost upper suspension brackets are attached to U1 & U2.

sorry if i seem sketchy, but would be easier to explain if i had my book at home.

but i need to make them longer to fit where the book says they should be (for the width of 478mm). Br7 would still be in the same place as I would use the 808 diagonal measurement. With the longer BR8+9 I get the correct length for BR7.

any chance of a photo please?

i wish i had my book as would like to double check the measurements.

Forgot my phone lead mate. Will take one tomorrow afternoon.

no prob, i,ll have my book with me tomorrow too & be able to check with the Saturn jig chassis.

sorry if i,ve not been able to help today:o

cheers

Nah you've been fine mate ta very much! probs be about 3pm when I've uploaded my pics.

I think you may have gone wrong somewhere along the line. I didn't have an issues when laying out the bottom rails of my chassis, or making it on 3d cad. Are you sure you have the correct placement of the other rails? e.g. BR12 and BR11 go in between BR5 and BR6.
