Got to be the cheapest way of checking if your sharp edges are in zone for IVA

http://cgi.ebay.co.uk/Polystyrene-Styrofoam-Modelling-Balls-10-pcs-x-100mm_W0QQitemZ350090111757QQcmdZViewItemQQptZLH_DefaultDomain_3?hash=item51 82ff2b0d&_trksid=p4634.c0.m14.l1262

if one of us buys ten then we could all chip in £2 each.

when i had my sva, the internal parts of the car where with a larger ball, believe it was 150 m/m, 100 m/mm is for outside radiouses i believe, hope this helps, suggest you check iva manual as some test stations are quite tough on this area, ie leighton buzzard.

If you do your own checks with a 150mm sphere in the interior of the car, then you'll be safe when the tester uses a 165mm one.

Same for the outside - use a 90mm or 95mm one.

Just my 2p's worth.

I have absolutely no idea how these balls are used to check radii.

I'm visualising them being held against stuff...then what?!

Anything that the sphre is able to make contact with has to have a radiused edge. Due to its shape it can't make contact with everything.
