would have been such a nice build if it was finished

Wow! good stuff

The clubman thing is just to see if it can be built economically and accurately at this stage, none of the off the shelf chassis kits would fit my lard arse

Hey, how about we B&T test the NC before and after you put the cage in. Also, I'd love to test the NA8 stock, then with the TB roll bar and then with the FM Brace frame. Whose B&T rig is that? (You should build your own... :lol:

)

OMFG!!! What haven't you done Danny? :shock:

You have an amazing eye for detail. I love all of your work! Where is that now?

I love solidworks!

Chassis is coming along nicely...

Solidworks even handles weld detail too!

Turned perspective on, looks more natural

It's coming together well Caffeine

. So how much does it weigh so far?

Maybe we should start a thread for solidworks models of automotive componentry that we have either drawn or found on the net? What do you guys think?

Cheers,
Danny

Sounds like a plan!

I haven't looked at the mass properties yet, i'll have to give it a go

Hrmmm.. SolidWorks says 62 kilos!

The book says it should weigh ~35 pounds in the state it's in...

I changed the weldment profile from 2mm wall thickness to 1.6mm, but that didn't have an effect.

Perhaps solidworks is calculating it based on solid tube!

Is the tube cross-section 25 x 25 x 1.6mm?....35lbs is only 16kg!!

Yep, I think it's missing a 1, 135 pounds makes a lot more sense...

I checked with solidworks, a 1 foot long length of my weldment profile came to 375 grams, which matches nicely with this list, which says 1 lineal foot of 1in by 1in, .063in square tube weighs 0.827lb, which is 375.12g

I just tried a solidworks model version of me (thanks to www.dpcars.net, which has a downloadable human body model suitable for checking layout / clearance in cars), in the standard 'book' chassis.

I think I'm going to need to expand things a fair bit!
