Steering wheel pad
OK so my local scrappy(s) don't have any sierras and admit they crush them and never keep any now! and I would rather not spend cash on a old
steering wheel just for the SVA/IVA so I knocked up a foam pad for the mountney wheel I have. It overlaps the spokes of the wheel and the centre ring
will be countersunk below the surface level of the foam (which I will cover with some "leatherette" . Anyone predict any problem with it?
Using the centre push horn so would rather not cover that. Is the aluminium ring not allowed at all i.e. it must all be padded? Whats the rules of the
game?

Could say that the whole steering wheel is not Type Approved... like my SVA guy did. Refused anything but original fitment wheels. Sierra one only in
other words.
Doesnt match the collapsible properties of the column, nor does the steering wheel boss.
Depends on the SVA guy.

hmmm, sva manual says nothing about type approved wheels, nor can i actually find anything about padding, or collapsable bosses. as long as
you've got 'protective steering' form any of the steering collumn diagrams, then should be fine... not sure why these testers
can't stick to the same rules

Mmmm....
Recently helped someone build a Westfield and it had this
 
Westfield SVA OK wheel
Basically flat spoked wheel put has a push fit pad which fits over the spokes hence my idea.
Anyone passed with a non-Sierra wheel?

Might be worth looking at a later Fiesta , Escort perhaps? they have the hexagonal fitting to suit the column

I've spoken to lots of people about this because i've got a very small wheel in mine. And it needs to be on a collaspible steering boss
and padding.
You have padded yours like i will try and pad mine so i hope your fine!
Let me know how you get on please
Thanks

OK boss isn't collapsible so that might be an issue. What about padded wheel and collapsible steering column?

well here's what the IVA draft says
"Steering wheel construction
It is vital that the wheel is constructed so as to minimise the risk of facial injuries or concussion. The rim of the wheel should be padded or at
least made
from a material which when deformed does not splinter or fragment. The centre boss should be padded or recessed below the level of the rim. Wheels
with a very deep dish are stiffer than flatter wheels and, as such will absorb less energy.
The centre boss will often be of a collapsible type comprising a convoluted crushable section or a series of metal fingers with a deliberate fold
introduced
to initiate a collapse.
Bolts used to secure the wheel to its boss (if exposed) should ideally be flush with the wheel surface but otherwise are required to meet the
radius
requirements if contactable."
it says The centre boss should be padded or recessed below the level of the rim. well, what steering wheel has the boss above the rim?
"The centre boss will often be of a collapsible type comprising a convoluted crushable section or a series of metal fingers with a deliberate
fold introduced

'often' doesn't seem to say it MUST be
"Bare metal spokes are allowed as long as they conform to the edge radius requirements. Components likely to catch in the driver’s clothing or
jewellery
are not permitted.
Note: It is possible to fit an 'aftermarket' steering wheel which has been approved for use on any design of column. These will be
referred to as
“Separate Technical Units”. If the presenter can provide satisfactory documentary evidence that this is the case, a “Separate Technical Unit” may
be
acceptable."

i reckon you'll be fine with the mountney wheel you have, padded in the middle as you have it

As Ben C said earlier,....
I had a fully padded Moutney steering wheel, with a colapsable boss
It failed SVA at Gillingham, I tried arguing the point but he was having none of it.
I know some centres accept after market wheels. Gillingham dont..
You may be ok, but do you want to take the chance of a fail?

Yep - the same for me ^^^^
you may get it passed by a tester at another venue but you'll certainly need a collapsable boss.

Although I fitted a Sierra steering wheel for SVA at Exeter, tester said he would've passed an aftermarket wheel provided it is fitted to a
collapsable boss.
His interpretation is that the Sierra wheel is designed to deform in an accident and a collapsable boss mimics this.
As regards not wanting to cover the horn push with leatherette, remember you don't need a horn for SVA and so covering it is not a problem in
this respect.
