Rear Wishbone design
Apologies if this has been asked before, but I was wondering if the Tiger Avon book goes into much detail about rear wishbones. I'm looking to
build a mid-engined car and am going to use an audi gearbox/ front suspension in the back.
The audi already uses a lower wishbone at the front (strut is the upper part) but of course it has the balljoint which i guess isnt needed for the
rear as of course its non-steering. So apart from attaching some sort of 'non'steer' bar to the upright to prevent the wheel from
turning, Im thinking that it would be simpler to replace the audi wishbones with my own but am having trouble finding info on their design- any help
most appreciated

Be very careful Chris when you wander around these other parts of the site.....
Full of wierdos who think engines should be in the FRONT........how odd...
Have you got/seen the Avon book?
It's as good as THE "book" for solid reliable info.........
Interpret that as you think fit....

Mr B to the rescue!
Thank you Alan for your reply- you have obviously done your homework. The other 30 people who viewed this msg and didnt reply- you're all in
detention for not knowing the Avon book!!
Seriously tho Alan- I will take ur advice and add it to my (growing) collection. Using the original (audi) lower wishbone is quite tempting, tho Im a
little unsure about how to prevent the wheel turning at this stage- Ill keep reading and thinking!!

Yep, as I said, as good as "the" book in it's own way......
Handy to flick through and um and ah a little, some reasonable pictures, half decent GRP section..........but technically as useful as an Escort
workshop manual..........is to a Vauxhall owner......
IMO of course.

Ah! but if Andrex could match the way those pages detach we'd have no need of the roll

Well, I bought both those books and they helped alot for me. Probly because the first time I saw a 7 was in Bath and I instantly feel in love. I had
to have the build books for it and it gave me a pretty good idea about how to build one. Ya they don't go into great detail but they still help
n00bies like myself. 
Best thing to do for a build....

I wonder if you will feel the same when you have started your build and things just don't add up?????

Ya probly after I start the build I won't find them as useful but I wouldn't even start the build with out them. So its kinda a catch 22

Well, I've said it before, and doubtless I'll say it again - the tiger book is not totally valueless for the purpose it was originally
intended. There may be more than a few errors, but provided you model everything in cad before you build it, everything works fine (or seems to so far
in my experience).
The quality of the constuction of the book could do with looking at though.

Bottom line IMO:
Buy them both. Expect lots of inspiration and ideas, but don't bank on accurate/trustworthy information. Double check everything...
There are many useful books to help building your own car..there two should be in your collection.

Ill get u butler!
Replies are like buses- u wait all day for one and then 12 come at once!
Seriously tho- thx for all the advice (including as the bbq starter kit and andrex substitute- no running out in crucial situations!)
I just bought Des Hammills "How to build and modify sportscar suspension" and was a bit peeved to find that its all theory and has little
practical advice. That is why I was keen to hear ur opinions on the Tiger book before shelling out on it

Des Hammill Book
Chris,
I purchsed the Des Hammill book and like you, on first read, was dissapointed with the lack of practical advice. But you have to remember that the
book is really aimed at suspension design from a clean sheet of paper. The advice given combined with CAD allows a suspension design to be checked
out far more thoroughly than making then modifying, and saves time.
For example I want to widen the front end but need to know the effect before I construct. Des gives invaluable advice on such things as steering rack
knucle joint position etc. so that the geometry can be checked out.
I find that CAD provides that valuable link between theory and practice and makes Des's advice extremely useful.
ATB.
