Spike, you've lost me there!!

I think that for the IVA they need a secondary fixing such as a bolt tapped into the mushroom, through the cast upright.

As far as calculations to back up the geometry, surely Ford 'must' have done some work on this. Although obviously the Ford upright is being used in a different situation.

And what item have you run past the local precision engineers?? The insert, the upright??

Also, what do you mean by "the stem is extended to fill the hub counter bore"??

hey guys , kinda lost me there too. anyone have a picture or drawing of how the inserts should look for them to sitt corectly in the uprights .how long should they be & whats the best way to fasten them ?
Samy

take a look at this
its the pdf somone posted before the big post loss
its not my drawing I take no responsibility for it but it may be usefull to you
ive made my mushrooms from ali theyre offset made close to this drg but i may have altered them
if someone can give me a valid reason then ill remake them in some stainless i have but for now they are ali
hope this helps
Ray:)

Glad you found that Ray
 

That's the one I posted many moons ago :)

Kindly drawn by my Nephew

I believe I still have them on my desktop system somewhere & have been meaning to rake it out and have a look :o
Since I have had my laptop, my poor old system has been packed up & put away.

Just as well the wife is blissfully unaware of how much that system cost me to build :eek: :D

hi ronnie i have the other two if you wat ill post them up too?

Cheers Ray :) :)

It'll be nice to have some of the lost posts back :cool:

EDIT

I can see no reason as to why alloy wouldn't be suitable for the inserts & a darn site easier to machine too ;)

ok heres the other two:)

hey guys , great drawings, thanks for the help.actualy i think i have them from before but its good to know i can make them out of ali but there´s one thing i dont realy understand & thats what the notches are for? & do i have to do anything else so that they dont pop out?
Cheers

The notches were put there to allow the use of a C spanner to help locate accurately if they are a little tight in the upright.
They can be left out if not needed.

In the UK some IVA stations require a secondary fixing point for the mushroom adapter.

A simple grub screw will do.
Personally I think the reason for a secondary fixing is to eliminate the risk of the insert lifting out of the upright if the pinch bolt becomes loose or snaps.

mine are made from ali.
