Dash Rolled bottom
Hi!,
I have the old Luego flat Carbon (effect) dash and have been reading that the bottom needs to have a 180 degree radius for SVA.....Is this true or
can I just put a bit of lagging on it to get it through the SVA then let the wind blow it off?
thanks
Dave Bailey.

Unfortunately lagging won't work as it's not considered rigid enough or permament enough.
I used some heater hose, cut down the middle and glued it onto the edge of the dash, then covered it in vinyl for good measure. Passed first
time...
Lots of glue and it would be permanent, however it would be difficult to blow off after

Dash
Hi
I put a rubber u section with about a 8mm radius on mine.
The SVA manual states that if it is not a 19mm radius it must be at least a 5mm radius and made of a deformable material.
I think the hardness spec is 50 shore.
I passed at Southampton with this without any comment from the tester.
Hope this helps

I think the question is about this:
 
dash lower edge
without studying the SVA manual I reckon the one on the left is ok but the radius needs to be 19 mm.
if you are able to make the edge like that on the right, that would be much better as you are less likely to amputate your legs - the SVA is a pain
in the butt and some parts are just plain stupid but there is usually some logic behind it even it is somewhat flawed.
now lets' wait for someone to say I am totally wrong ......

I have cast aside my perfectly good flat carbon dash and am in the process of making a mould to make another with a ~19mm radius along the bottom
edge. I am aiming to manufacture somewhere between the two images above, and use edging along the cut edge. I agree this is an area that would make
sense in terms of safety.
It sounds rather subjective as to what will pass and what wont, but i would always be cautious and OTT rather than have a retest for something silly!

As above i dont believe it needs to be 180deg but must be 19mm rad if solid or 5mm deformable to pass (see manual for definition of deformable -
something like you have to be able to push thumb into it with reasonable force but not too much so that you cant feel the hard surface underneath iirc
- hence the 50 shore reference above, although other similar shores may also be OK.)

My interpretation was that if you have a deformable adash, then you can have a 5mm deformable radius. If you have a solid dash, you must have 19mm
radius. Other people seem to have passed with a combination of both...

Would a piece of tinpot door or boot seal pushed onto the edge be considered deformable and OK for SVA?
