just wondering if you guys can shed some light on chassis prep to a mk 2 golf, im about to start my bare shell track car build and and tips pointers off of you chassis gurus would come greatly received .
Im going to be using a fettled abf lump so ill be stitch welding the bay up etc , ordered my 6 point cage more than likely going to extend it through to the bulk head to make it 8 point .
toying with the idea of stripping all the underseal off of the bottom of the car and spot welding all seams to eliminate as much flex as possible . anyone done this ? usually done on a chassis spit .
if theres anything ive missed , any tips pointers any chassis strengthening tips that might help let me know .
like i say the build thread will be starting soon so keep eyes peeled
cheers people , hope to see you on track in the near future .

If you're serious, weld a Corrado tunnel in.
It's much higher and will give the car more chassis rigidity out of the box.
Go look at VeeWgti16v's build thread - he's been busying himself stiffening his shell up with seam welding and removing excess weight. Should give you a good pictorial guide, even if he is a c*cksucker.

im not that serious lol , thanks for the heads up tho . will check his thread out .

charming!
its definately worthwhile stitching the shell. just go easy grinding back to bare metal, its very easy to thin the metal causing you to blow holes when it comes to welding
i havent done underneath yet as my welder refuses to weld upside down! (dont blame him tbh) so am interested in what you come up with to turn the car over. i was thinking a couple of matresses to tip the shell onto and prop it up with a scaffold pole or something
buy yourself a spot weld drill, they are awesome!
-
also, remove ALL the seam sealer from the seams, even use a screwdriver to open them up, remove sealer and hammer them closed again. it will affect the quality of the welds

Yeah go easy on that grinding - it can cause holes in hands. :grin:
Danny was talking about fabbing up a 'car spit' to turn his Golf over to do the underside of it. Might be worth having a chat with him to see how far he's got.
My new workshop/barn has a lot of steel lying about, so it Danny's not ordered the steel to make his it might be easier for me to fab something up from 'scap' steel that we can all use to do the same thing.

2/10 - see teacher after lesson :grin:

I should stop trying to hold down a job as well as this forum thing - it would give me more time to correct my typos :tongue:

i dont quite get what u mean ?? get rid of the seaam sealer and open up the metal seams using a screw driver ?
-
where two panels meet the metal overlaps and is spot welded, right? theres gonna be seam sealant between the two layers of metal as well as over the top. You can open up the two layers in between the spot welds and dig out more seam sealant, then hammer closed the gap and weld it.
for some reason you get sh!t welds if there is sealer in between two bits of metal
its a long boring job mate, the welding doesnt take long compared to the prep! i suppose its a bit like painting.
-
ahh , im totally with you now , just out of interest mate , where did u get your rear strut brace / harness bar ?
thanks mate .
-
i got it from merlin motorsport at castle combe. its just a bit of rollcage tubing. might be worth deciding now what cage your gonna use and buy it the same diameter
-
just ordered a Peter Lloyd cage , just a basic 6 point , probably will add to it , just easier to start with a basic cage already made .
-
yeah im gonna do the same, buy all the bent tubes and add to them with straight tubes. its not hard to profile the end of a tube but bending them is a bit specialist

How much that set you back?

its just a generic picture though
-
its only a basic bolt in 6 point , im gonna chop the mounting plates off the bottom of the legs and fab up a nice box section for the cage to weld to . weld all the cage together and just add bars where appropriate .
-
I reckon it'll be cheaper to get my uncle to knock something up, even with having to drive the car down to Bodmin.

scaffold spec roll cage :grin: if its cheap and decent , why not mate .
veedubgti16v what did u use to prep your inner arches for stich welding ? that wire grinder attachment that took your knuckle off ??

He's cornish farmer who builds trailers as a 2nd income so has a pipe binder and 40 years welding experience. I'd just have to supply the right tubing and some beer!
Problem is I live in Hampshire so it's a pain getting the car down there and then getting back, then going back to get it.
