dashboard lower edge trim for IVA
I'm making my dashboard from fairly thin mdf and according to the IVA manual the lower edge must have "... a radius of curvature of not
less than 19mm or 5mm and covered with a non-rigid material."
I can make a 19mm+ curved edge from a couple of bits of wooden quadrant (its all going to be covered, so the joins will not be seen). However, I
would prefer to go for the 5mm radius. What have people used to comply with the non-rigid material requirement? presumably it has to be non-rigid
enough but not too soft and also there presumably has to be a minimum thickness of it. What do Mr and Mrs IVA inspector consider to be
acceptable?
Is there an off-the shelf edging material that is IVA proof?

A 19mm radius is 1/2 of a 38mm tube
The smaller but padded radius needs a material similar to your tin top dash material.
Edge trim does not have enough give, perhaps a layer or two of yoga mat would do it.
The material give was described to me as similar to pushing your thumb nail in a sort erasure

My dash was padded with a single thickness of yoga mat, but this wasn't enough. The tester said he could still feel the dash edge when he pushed
it in. Had to add a bit of tubular / 'D' rubber trim for the retest. So double yoga mat may be a good guide. Maybe even camping mat,
rather than yoga mat! Or something denser, as Snapper suggests.

I sliced washing machine outlet pipe. Bends very nice. Stuck it with silicon but stays in place anyway over mdf edge.

Yep I used 40mm waste pipe
19mm radius means you can get away with little or no padding
The smaller radius needs dense padding, camping mat would do it but does not bend easily

i used pipe insulation covered in an old pair of jeans. if it looks perminant then you will have no problems, if it looks temporary they wont accept
it.

Thanks for the advice, I will experiment with what I have in the garage and report back to add my solution to the list.
Steve (gough)- looking at the pic of yours, was the IVA inspector OK with the edge where the dash and scuttle connect to the side of the car, as it
looks as though you have not applied the 19mm radius to that bit. Is it not touched by the sphere?

The rule applies to the lower edge of the dash - the edge you can see is the edge of the fibreglass scuttle. - I had a question in my mind as to
whether he would have an issue with the bottom (sloping) edge of the dash where the instruments are, as that part is not radiused at all - but in the
event, he never mentioned that part. You can see better in this pic that the point you were wondering about is not 'bottom edge of
dash'.....
