BR7 tube question

[Adam R.]

BR7 should be:

409,92mm like in new fig. 4.2

or

428mm from page 161

and how many mm should be between BR7 and BR10 ?

[HandyAndy]

not with you there ? :confused:

when i cut BR7 i used the dimension from page 161 which is 428mm.

where do you get the dimensions of 409,92mm in fig 4.2 from?

long time ago on the forum was corrected pdf with fig 4.2 and BR7 are 409,92

i don`t have this file but maybe somebody have

I cut my BR7 to 428mm as per cutting list on page 161

Looking at figure 4.2 on page 34 the overall dimensions given to the outsides of BR8 & BR9 is given as 478mm

Deduct 50mm for those 2 tubes 478mm - 50mm = 428mm length for tube BR7 ;)

The drawing is correct as far as I know, I do not remember any amendments to this part of the chassis.

No idea as to where you get the 409.92mm from !!??( 410mm in the real world ) :D :confused: :confused:

now from the oryginal 4.2 everythink is correct :D

[HandyAndy]

the dimension of 409.92 is the dimension of where BR8 & BR9 meet the rails BR1 & BR2 NOT the position of BR7, which is why i couldn,t understand your original post question.

i would suggest you place BR7 as per the book dimensions ;) :) stated on page 34, fig 4.2

cheers

I don't know where that drawing has sprung up from :confused:

The front section of that drawing looks to be narrower than the book one.

You might want to cross-reference those diagonal measuments against the ones shown in fig 4.2 on page 34 ;)

If you build your chassis to that layout, I don't fancy your chances of fitting the front suspension brackets :eek::eek:

Now I build the same as fig. 4.2
