Sorry,meant Richard not Phil.

Thanks Phil for the measurements...

Just more confusing...

John

Phil,

Thanks very much, that confirms what I believed I had done with the negative camber versions that I have made for our Minor. As standard there is a 0.125" (approx.) washer, and sometimes more, between the chassis rail and the head of the eye bolt, and I calculated that I needed an additional 0.500" offset, so starting with 0.875", I would need 0.875" + 0.125" +0.500" = 1.500" to give the additional 0.500" offset.

I already have a stiffener on the side of the chassis rail that is ~0.125", so for me the 0.875" dimension would need to be 1.375", which checking the drawing I made at the time it is! Sounds a bit tortuous, but I had to make sure that I am starting from the correct datum point, if I am to make eye bolts for someone other than myself.

John and I are in communication about the offset(s) he needs, so when the material arrives next week, I will be able to start making them immediately.

Richard
Happy to be of help.
What grade steel/material are you making them from?

Phil

Bright EN3, which is in effect a good quality mild steel. The original is a forging that will be a similar metallurgic structure.

Richard
Many thanks for that information.

I have made some longer eye bolt pivot pins in EN8. Done to accommodate improved anti-roll bar rear end mounting brackets and link.
The mount brackets fit between the thick/thin arms so requires 9mm spacers and therefore longer eye bolt pins to suit.
The Marina/Ital lower swivel trunnion pin has longer threaded ends and can be used with the 9mm spacers without difficulty.
The rear thick arm remains in its original position and the thin arm is spaced forward therefore steering geometry remains the same.

Phil

Phil,

An interesting combination of changes to make. For the pins, EN8 is a good choice, as it is stronger and tougher than EN3, so should wear better as well.

Do you have any pictures of the set-up?

Richard
In due course I will post some photos.

Unfortunately no good for the type of antiroll bar fitted to your Minor as the end of the 1970s period antiroll bar fitted to my Minor is formed into a loop.
Modified Vauxhall Astra antiroll bar links are used between the bracket (fitted between the thick/thin arms) and the loop of the antiroll bar.

Phil

John,

As I cannot attach a picture to a 'Private Message', the picture of the new negative camber eye bolts is attached here. In the post to you tomorrow.

Richard
You have done a nice job there.
Phil

Very impressive work Richard. Lucky John!

Re: the pins in the image above is the eyelet off set from the pin centre line or is it an illusion from the shadows?

The whole eye bolt is completely symmetrical about the pin diameter - including the chamfers! The picture was taken quite close up, so the view has become quite distorted.
