My chassis build

[geeman]

YAY... i fabricated a bracket for the steering and fitted that, i then spent some time trying to accurately measure the extension require and it came to just under 400mm extension. one thing that you may all object to me doing though is the fact that i used 25mm square tubing wiht a 2.5mm wall as that was the only suitable metal i had for it. There is a problem though, the extension seems to be hitting u2 and as it is square tubingwhen i turn the wheen when it gets to the right andgle on the edge of the square tubing, it pushes the extention away from u2., but it still turns freely, but it is touching u2, i can see from bonzos pic the coloumn is extremely close to u2, but mine is just about touching.

damn. just ran into abit of a problem, i dont have the keys atm, so anyone know how to disable the steering wheel lock without them

[deezee]

I'm afraid the only way I know involves a screwdriver and wrecks the lock.... misspent youth I guess.

Looks like you just had the same day I did.

It took me the whole day just to get the steering support brackets right, not helped by my total inability to calculate the correct angles to cut. I've descided that me and compound mitres just don't mix, but I have some excuse in that I've a MT75 gearbox so the transmission tunnel angles don't match what's in the book. I also saw some posts on another thread that suggested mounting the bracket on top of the top tube made fitting the side panels harder, so mounted it to the side of the tube instead.

Out of interest, what have you made the distance from the centreline of the steering column to the centreline of the chassis?

Hi, i eventually got it all fitted and uploaded a few ppics if it helps anyone,(all in the link in my sig)


I measured the distance and along tr8 it is just over 250mm from the centre of steering column, to centre of chassis.


Also for those interested i made the braket i threw out with some 3mm stip bent and bent it around the steering column and then welded and drilled some scrap 3mm steel around it.(also if youre wondering i will eventually get around to drilling holes for the pinch bolt(oh yeah and i will add some bracing in the bracket as well eventually))

Maybe I'm being an idiot, or I've not read all your posts right, but isn't your steering wheel support frame not in the right place. My Haynes book isn't at home, so I don't know the tube name. But the one on the right side of the steering wheel support frame.... doesn't that line up to the outside of the rail?

You're right - it does line up to the outside of the rail in the book, but a couple of people have suggested that fitting the bodywork is easier if you mount it on the inside like geeman (and I) have. So long as the top of SW2 is at the correct height and distance from TR8 I can't see any reason why it would make a difference.

oh yeah, the top part of the the steering support frame is shortend by 25mm so the frame doesnt sit on tr2 (the top rail on the side if tr2 isnt right) this is so the fibregrass stuff from fabby fits better as it sits on that side edge. hopw thats clear

Also i will be putting some box section under the bit that is sitting on the edge of tr2 to support it.

HI
Im now on my second roadster. I have put my supports as geeman. It saves cutting the scuttle close to the out side edge and stopping it from starring(cracking). Not a problem if you are making one form steel.

[les g]

hi guys
yes that is exactly what fabby recommends
and then brace it with a a bit of box in the area just below the the blue disc in geemans picture
cheers geeman that has really cleared up what i was trying to put across in my previous post
cheers les g..
