In response to a request in the Avon section, I've converted a drawing showing the method I'm using to fit IRS to a book chasis into PDF
format.

Wow!!
70 views and 70 downloads.
I'd appreciate comment and constructive criticism, nothing is set in stone as yet.
Mick
looks good but at the bottom of the chassis is flat rather than on a rake cant this be changed?? and do you have the measurements for all this
Morf
Why would you want the base of the chassis to rise at the rear? I would think the IRS loads are transmitted more efficiently through a flat
construction. (The IRS theory gets more complex with angled wishbone mounts aswell).
Mick
For those who might want a bit of inspiration I've ressurected this thread.
I have drawings of all the components except the upper bones which have still to be finalised.
This design is untested but appears to work on 'paper'
Drawing is to scale
Mick
have you got any other drawings? for the wish bones etc, with measurments? Please. 
Well done Mick.
Although we have aproached diagonal bracing differently, your wish bone size and mounting positions look very similar to mine.
I wish I could draw like you. Never could get the hang of cad and the like.
Is Morf refering to the chassis bottom rising before or after the rearmost w/b mount cross member?
The rear of mine goes up at the back in the fuel tank area, but like you say, keep it simple for the bone mounts.

p.s. my sig seems appropriate for this thread 
I would be willing to post more drawings however my trial version drawing to PDF converter has expired, can anyone point me in the direction of a good
preferably free one?
Cheers Mick
It looks like you'll be cramped for tank space Mick. You could make the back a bit longer without any problems or you'll need a complicated (read expensive) shape for the fuel tank.
Has the roll center location/stability been calculated for this?
