The book shows a picture of a set of wishbones that were bent. the shape was more of "U" shape rather than triangle. has any made a set of these?

If so, could you help me out with the plans?

thanks

if you mean the top front wishbones i think these are the mk style jobbies.

Ned.

I'm looking for something like these. But, I would like the Bottoms to look like the tops.
still the MK styles?

there was a thread a while back (re racing iirc) about the curved mk bottom ones having an inherent weakness from the way the balljoint plate was mounted to the curved wishbone tubes. i'll see if i can find it.

Ned.

not the thread i was thinking of, but check this one:
http://www.locostbuilders.co.uk/viewthread.php?tid=18432 it does go off at a tangent part way thorugh though.

The better suppliers are now using designs similar to the one below (in this case from Marc Nordon Racing http://www.mnrltd.co.uk/Suspension%20Components.html )

MK and GTS are similar (I would have use a GTS one an an illustration but Darrens web site seems to have more broken links each time I visit it)

Hi

If the gusset plate on the bottom w/b is curved,
and the tube for the top w/b is bent to more or less the same angle,
they sort of match..... well nearly.

I made mine to this drawing using HB Cad, no problems at SVA on self centring

Curved tubes aren't a major problem on the either wishbone on the lower wishbone it is really case of getting detail design of the web plate and is position correct but this adds weight. So the Vee design is more efficient and stronger.



On the top wishbone a curved design has the advantage of giving a better weld geometry for the top ball joint tube -- the book design is not the easiest weld to finish properly when using MIG --- a TIG is a bit easier to get into the "V" . However the curved design will be a lot less stiff and need heavier tube.

It's relatively easy to calculate the compressive load on the back tube of the lower wishbone while braking at 1G.
rearward force at lower balljoint is ~2x force at contact patch, for a 1/2 ton car thats ~200kgf (front remember, one side) This is shared between tension & compression of front & back and divided by the cos of the tube angle: total say 350kg compression.
That's more weight than I'd like to put on a 20" long bent peice of 16s gauge tube. And that's before you add any cornering forces or hit a kerb or add the bending moment due to the suspension unit.
I'd definately keep the bottom bones tubes straight. I'm keeping the top ones straight as well!!!
