someone save me the maths. how much metal do I order
 

hi

just trying to work out price of the metal for my chassis and get quotes.

how much do I need?

book seems to say 1.6mm 25mm box. but what length in total?

has anyone ordered in all of their metal in one hit? do you have your order so I can at least sound like I know what I am ordering

thanks

Hi, I ordered about 37 meters I think it was. But I did not buy the erw as the book suggests, it's much cheaper to buy normal 25mm box section, I asked for a 2mm wall, so that it was a little harder to burn through than the 1.6mm. My box section came in 7.5meter lengths, and cost £54 including vat. If I wanted erw, it was almost £150. :cool:

ok sooo 37 meters of 25mm box. what does erw stand for? 2mm or 1.6mm ill look at wieght differance later but 2 is prob safer with 200ish bhp

what other metal is needed. want to get it all to have some bargining power if u catch my drift.

Hi Nick.

ERW = electrically resistant welded CDS = cold drawn steel / seamless.

Hi,
There is a post in the FAQ's about that.

Worth to have a look at all the FAQ as well as the "Book amendments and extra guides" from the stickys section before starting.

Good luck with the build :)

thanks

how on earth did I miss those!!!

cheers

That's because AshG stashed all the important sticky topics into one 'Stickies' thread.

ashg has a lot to answer for.:D ... he saves all the best bits of the forum..... he has used the saab turbo lump.:cool: ...just wish he lived next door :)

Ha ha, in fact not, he rearranged the saved best bits so they are harder to find. But he did publish his build log in a magazine and later in a booklet:

As standard, ERW tubes come in 6.1m lengths, RHS comes in 7.65m lengths.

Approx cost (trade) for ERW is around £850 per tonne, (or £0.85p per kg)
Approx cost (trade) for RHS is around £620 per tonne, (or £0.62p per kg)

My chassis was 6 lengths 25x25x1.6 ERW and 2 lengths 19x19x1.6 ERW. Should of been around £65 + VAT, but I got it for free :)
