Chrome wishbones

I've had my wishbones chromed. Very very good quality work at a reasonable cost. If anyone wants info on the firm( Greenwich area) let me know. Rescued attachment DSCF0066.JPG

More details please

they look really good, did you get the springs done as well ?

How much?

We really need to see a few more piccies of your build....

What is reasonable cost?

Do they do Nickel plating ?

I always thought there was some technical reason why racing car suspension used to be nickel rather than Chrome, I expect someone will fill me in!!!!

Looks good though.......................................

On racecars it is harder to see fractures and cracks etc when the components are chrome plated

Harder to see than through the standard powdercoating?????????????

The problem with chrome plating is that the chrome is very brittle, like glass. This is not a problem in most situations as the underlying metal remains static.

In a wishbone the mild steel tube is always flexing a bit. The chrome cracks, and the crack then propagates into the steel underneath. It's the same effect as making a significant nick on the surface of unplated mild steel - sooner or later the crack will propagate into the material.

I've seen a recommendation somewhere (Carroll Smith's book?) that recommended cadmium plating instead of chromium - not so shiny, but as flexible as the steel underneath. It has the bonus of being cheaper than chrome as well! And it comes in both silvery and goldy colours.

P.S. In normal use you'll probably find that you have no trouble whatsoever - apart from getting pee'd off with polishing.

I've stuffed some build pictures into my photo archive at the top of the screen. Got some of the Tiger open day last year as well

I had to grind some of the top wishbone to get the camber angle. Presumably you checked yours before plating.

Oh BTW one of the things that I wish I had done was to put another mount on the rear of the diff to the transverse bar right by it. I don't know why this isn't done.
Should help with the reactive torque.
Rob of Mirak cars has had problems with both his demonstrator cars having the diffs move under acceloration.
I havnt notice mine move to date however the clutch is slipping.
Easy mod to make whist area is clear.
