peterm135 Posted January 18, 2012 Posted January 18, 2012 scrutineers have been asked to particularly check welding I'm not having a go or anything but in this world of litigation, how are they going to be sure ? I have seen welds that look fantastic and almost fell apart in your hand. I know its a case of looks good should be good, but.................... Quote
peterg Posted January 18, 2012 Posted January 18, 2012 That's the problem, even a really hefty tug on the shoulder straps won't come anywhere near the forces that the mounts would go through in a proper impact so it'll be very hard to check their integrity... Personally I would always have that sort of thing done by a professional (ie the factory or a local engineering company) rather thando it myself no matter how confident I felt at welding as an amateur Quote
westy turbo Posted January 18, 2012 Posted January 18, 2012 Λ what he said Λ no risks on that!!!!! Quote

I think it's more the opposite way round Peter, as you are quite right, in may look OK but could be wrong. However if it looks bad, then it will fail scrutineering. My point is that they have been asked to look out for this, so if you do something different be prepared to prove what you have done is OK. Do remember if something breaks it's still your fault, not the scrutineer who is wrong, they are there to check for obvious faults, not to take any liability if it's wrong. Quote

Nick Algar - Competition Secretary Posted January 23, 2012 Posted January 23, 2012 Well today is D day for welding on new threaded inserts for the top harness mounting! I'll post some photos later...... Looking forward to it Ian, mind in NI you can get away with almost anything at Scrutineering. When I see you ask me about the wheel falling off, it's a good one :d not that I enjoyed the wheel falling off mind, but at least it did it at the big bottom 180 bend, not the 140MPH straight just before it Quote
ianstewartshouse Posted January 23, 2012 Posted January 23, 2012 Hi Nick, thats somthing i dont want to copy!! Well here are the photos First insert welded in Second insert welded in Welded in structure for mounting JK seats Harness top straps mounted Harness in place and seat bolted down All seemed to go ok, what do you all think? Even squeezed myself into the JK with HANs and helmet on and feels perfect (well will do when i've lost some weight!! Ian Quote
westy turbo Posted January 25, 2012 Posted January 25, 2012 Great work Ian! you had to cut the seat to fit the extra crutch strap? Quote
ianstewartshouse Posted January 25, 2012 Posted January 25, 2012 Hi Westy, I've heard others talking about cutting the seat but I got JK to cut them before sending them Quote
ianstewartshouse Posted January 26, 2012 Posted January 26, 2012 Do you have the JK fiberglass base on the seats? If so JK cut a 100mm x 100mm square in the bottom of the base and just the small hole you see in the pictures in the seat itself. Don't forget to put the hole in the base to suit the harness crotch strap sloping towards the back of the seat slightly (FIA diagram shows 0-20 degrees) ie buckle connection closer to pedals, bolted connection slightly further to the rear of the car. Hope that makes sense! Quote
jouhar Posted January 26, 2012 Posted January 26, 2012 What was the distance between the old mounts.....and what distance do you now have between the new mounts ? Thanks very much Regards Quote
ianstewartshouse Posted January 26, 2012 Posted January 26, 2012 Jouhar, it depends on the distance between the back of the HANS device and the mounts for your harness. On mine the distance was 175mm which equated to 165mm between mounts. FIA 'guide for the use of HANS in international Motorsport' gives details. Google it to find it. Hope this helps Ian Quote
