James,

From looking at the book the 25 degree end does not have a compound on it.

Cheers Ginge

It's a metal cup around the colum bush....:p
It was standard fitment to my column.
So nothing special.

As for the whole steering column support.
It seems to me some people are still trying to make it more complicated than it needs to be.
Just tack weld the CP16's into place in the centre .
Then bolt on the stering column.
The other tubes just need to support these, so really don't matter where they go.
Providing the fit under the scuttle.

gingea1pom - that is what i thought but there is another veiw of it on the drawing that shows the end having a 9 degree cut on it, i think i'm just gonna ignore it! lol

My way...
Simple, like me.:D

what height is the scuttle? my support frame sits up roughtly 165mm will it go under?

you should be ok at that height, there is quite alot of space above the standard support frame to the underside of the scuttle, the scuttle doesn,t sit on top of the support frame.

hope that helps.

cheers

Just to add to this in a "don't do what I did" kind of way:
I am building my own scuttle, this presents a couple of problems with the book design - the first is that the steering column comes to close to TR9 to allow the scuttle cross member to fit without cutting it to allow the column to pass through. The second is that the steering column support bracket can not sit on top of the top rail as it would get in the way of the scuttle. It is far better to make the steering support so it welds on to the side of the top rail (like shown in Dogwood's Post) if you are fitting a fabricated scuttle.
I will have to cut mine off and do it again - a complete bitch as the chasis is painted.:mad: Wish I had thought of it earlier.

I'm working on this bit at the moment as well and having a bit of trouble. I tacked sw1-3 together and then tried to fit with the front edge of them 456mm back from tr8 but found that it wouldn't then reach over to the transmission tunnel? I did then notice that the picture in the book looked more like the below picture (I know it's bad...) Can anyone confirm that this is the correct way to assemble the frame? Also should I just leave fitting the cp15 plates until later when I can trial fit the steering column or does anyone have some measurements they can give me for where to position them?

To be honest i did all mine by eye, and its turned out good (so far;) ) I got so fed up with trying to make sense of the dimensions in the book, im a bit simple like that.

sometimes its a lot simpler and ends up the same anyway!

You did it the right way. I think I've seen people cutting a corner and welding the top tube open, but the book design is intended to be closed.

Ash has posted a photo of a ruler against the CP15 plates on his car somewhere on the forum.
