Default Upright 1 & 2 position

Hi
Can anyone tell tell me if the bottom outer edge of U1 should line up with the outer edge of br7. On some pictures some have it set back like on the book drawings and others have it flush. I'm just a bit concerned that it could lead to problems when mounting the suspension brackets later on if this is put in the wrong place. looking at the mx5 guide from Saturn one of the photos shows it flush so as we are building an mx5 based car we have put ours flush for now.
I may make my suspension brackets next so i can see whats what.

The amendment to the book from Haynes states

“U1 and U2 should be fixed next, noting that they are placed square to rail BR7 at the bottom.
The top front corner is aligned with the outside of the rails TR1/TR2.”

Many thanks

Andy

If you've got the jigs and brackets, I'd definitely use them to position U1 and 2 to suit.
I placed mine so the rear top corners of U1/2 were flush with the top rails.
Luckily this had put them in the ideal position when I came to add the brackets.
The front top corners of U1/2 protruded out, but I ground grind them flush with the top rails before I fully welded them.
I think if you place them with the front top corner flush you end up having to pack the brackets out with spacers (though I could be wrong ).

I'd definately be careful with these, especially the one thats on the drivers side as if its too far into the engine bay area at the bottom side it'll foul your steering column extension which will cause all sorts of problems to fix!

I just started making the brackets at lunch time so i can jig it up and test where to put them. I modeled it on Autodesk inventor which i would of checked it on but my laptop has burned out so that's not an option anymore.

Ill report back when i have an answer.

From what I worked out on inventor at work yesterday I reckon that the optimum place to put them would be offset in 2mm from br8/9.

But this is on the computer! Back in the real world I think we will wait to position them when the brackets and jigs are built.

Put them flush with the outer edge of TR1 and TR2 but just tack them for now. If you can then certainly place them as far out as you while lining up the upper wishbone brackets. You can also line up the steering column at the same time making sure you have some clearance for the column. When welding the extension to the column just make sure that it is not eccentric as this will move it towards the upright as you turn the column.

It's not too bad....>AndyH

I tried to get a copy of inventor a few months ago but the costs for a small business is far too much to justify. It does look rather good though Andy. Yes about 2mm in from the bottom rails is about correct. The edge at top rail will protrude slightly but its no problem to grind flush and weld.

We have only just started using it at work so i'm still learning it at the moment.
I know what you mean about the price of it, it cost approximately £7000 for the software, plus a subscription to autodesk support. then £6000 for a new computer. And finally the cost of 5 days training.
Certainly not cheep.
