New month, same IVA work

I have a plan. I want to get the IVA done before the Malvern kit car show, but November/December are typically busy times for me and the family. So I'm going to put my application in at the end of the year, and hopefully get a January/February test. On the (hopeful) assumption that it passes, that gives me time to get it registered for it's first long trip. 

On that note, more IVA stuff. The interior edges are going well;



I've got the two outside edges on there. The tape certainly seems to hold them on securely, I just hope it's enough for IVA. I do need to test the seat movement with all edges in place though, just in case they get caught and torn off or something weird. That ended up with a 7mm diameter so 3.5mm radius, well in spec. I just need to do the tunnel edges next.

The suspension bolts now protrude from the nut an appropriate length, and I also got a washer in there for good measure;


There's still the stack of washers in between the suspension bars, I think it's ok as they're in compression but there's a possibility the IVA man won't like the design and I'll have to replace them with a solid piece. Of course that is the long term plan but only after I get the camber set correctly. 

The handbrake cables are now secure;





To be honest I think I've gone a bit overboard with them but as with everything IVA I'd rather go overboard than 'underboard'. 

The steering got sorted too. The background to this was that at full droop and full lock the steering arms were hitting the suspension arm. This isn't necessarily a fail as the test is done at static load rather than full compression, and they don't touch at that point. But again (most of) the IVA rules are there to cover issues, and this was an issue. It's a simple solution, I'm back to steering limiters. So now rather than nearly three turns lock to lock, it's only two turns. If you remember I'd put the limiters on a while back but they limited the steering to about 1.5 turns which is unusable on any road. It didn't take much tweaking to get them to where I want them. 

Away from IVA, I thought some stickers might be good;


And because I've now finished everything suspension related the hubcaps were added. I have to admit I think they could benefit from some paint, the matt black looks like a failed photoshop edit!

What's left now?

  • Covers for the front grille. The one edge is too sharp so it needs a cover. A quick session with a ruler shows that I have 8mm clearance on the face before it gets to the rivet. It's only about 2mm deep before it gets to mesh, and it's about 25cm long (so two prints again. I'll modify the existing one, it'll have to be quite bulbous to meet the curve requirements but avoid the mesh and the rivets. 
  • Handbrake covers
  • Wiring final touches.
Hmm, that is an impressively small list! I think there might be one more job... complete the IVA paperwork. I might as well crack on with that.
