How do i make my dash board safe???
I have made a dash board out of 6mm external ply covered with a layer of foam and then vinyl sheeting. I thought that the foam padding would be enough
for sva, David J has very kindly had a look at the car yesterday and informed me that the padding had to be hard padding to pass, or it should have a
19mm radius.
would the dash board pass if i put herring bone edge piping (the type used for the external wings) along the bottom of the panel?

I would go with a 19mm radius edge with padding and vinyl .

That might not be acceptable to the inspector, i used 25mm dia tube and covered it in foam and then vinyl . if its hard not padded ,it must be the
19mm radius ie 38mm dia which is a bit excessive.Maybe you could use a broom handle with a slot routed in it for the bottom of the dash to fit in and
then cover with foam and vinyl as per existing dash.

You could do exactly what I did.
I bought some 19mm coolant hose and then split it along it's length.
Then I pushed it onto the bottom of the dash and secured it behind with staples, can't be seen from the front and after SVA the staples just
happen to fall out!!
HTH,
Rich.

Don't forget that the critical dimension is 19mm RADIUS, not diameter - you'll need 38mm dia pipe (roughly 1.5" )
cheers,

The radius is only critical if it is a hard surface, if padded it just needs to be curved to a sensible radius.

It does have to be padded quite firmly, and the tester must not be able to feel the hard bit underneath the padding.
If it's properly padded, the radius is 5mm.

Coolant pipe will be fine, he didn't even question mine, 19mm as already mentioned is for hard surface, the pipe is rubber and therfore fine.
