  1. Anyone interested in approx 50 odd Low Flying magazines spanning from May 2014 to May 2022?

    Not a continuous run. Most are in good/very good condition. A handful aren't.

    If anyone would like them, and can pickup from the Coventry area, they are yours.

    Thanks

  2. This is a pair of black Luke harnesses with the 'Caterham' legend on the shoulder straps. The passenger side is a 4 point, the driver side has the additional crutch strap. FIA expiry date on them is 2007 so I assume they were made early 2000s.

    I bought these from another BC member in 2014 but then ended up buying some new Titons to have 6 point on both sides and so didn't use these. They look to be in reasonable condition and some of the metalwork has cosmetic wear and tear. Message me for more details and photos.

    I would definitely prefer pickup / drop off in the local area (Coventry/Warwick) so the buyer can inspect first and be happy before parting with any money. 

    Belts only (no bolts/fixings) £25

     

     

     

  3. I've just bought some Titon harnesses from Prima Motorsport. They have been great and very patient and accommodating various requirements.

    However I have a question with the cranked/angled anchor plate used for the shoulder straps. As supplied they are angled upwards, whereas the belts slope downwards to meet the underside of the headrest. 

    See: https://www.flickr.com/photos/30324212@N04/15524903465/

     

    The bolts holding the anchor plates aren't fully done up in that photo, when they are the plate becomes more horizontal and the angle between the 'crank' and the belt increases even more.

    Prima say all their belts are made this way as normally the mounting point is below the seat top. They don't do a flat anchor plate.

    IIRC there are other Caterham owners that have Titon harnesses from Prima, so what did they do? Use the harness as is? Is it ok like that? (I would much prefer it to be a flat plate which is more inline with the belt angle or even reverse the anchor plate so it is 'cranked' down).

    Any comments thoughts? Thanks

    (PS I have no idea why this appears as one big paragraph. 'Ive added plenty of line returns and paragraphs to try and format it nicely..)

  4. Note to self: Remember never, ever, assume anything.

     

    Just because the bolt removed from the top harness mounting point is 5/16ths, it doesn't mean the hole they came out of is actually 5/16ths *eek*

     

    At some point, someone used a combination of washers, rubber spacers and nylocks to allow a Willians harnesses, with a 5/16ths hole in the top mounting point to be 'mounted' in a 7/16ths hole with a 5/16th bolt.

     

    The top mounting point is 'T' shaped on this particular harness, making it very thin where it bolts to the car. You couldn't open the hole out to 7/16ths there would be so little meat left on each side. A quick play with a micrometer says it would be very approx 3.8mm (or 5/32") left on each side if drilled to take a 7/16ths bolt. Hence the rather unorthodox mounting technique I assume.

     

    Relived to have got to the bottom of it, not sure I would have wanted to tested it in an accident...

  5. Thanks for the replies.

     

    Its good to know I'm not the only one with 5/16th bolts, and that a bush/top hat etc is an acceptable method of sorting out the problem. I could make some up (have a lathe), or might just speak to Redline, however having looked at the end of the lap belt, first I need to make sure that I can make this work.

     

    It turns out the current lap belt ends are anchored by 7/16ths eyes (this sort of thing here) and are fixed with a snap type fitting (http://www.stroudsafety.com/Images/Restraints-SeatBeltEndsLg.jpg) which the replacement belts don't have.

     

    So I need to unscrew the eyes, but I just have to assure myself that they are screwed into a captive nut or threaded boss, rather than just a nylock nut (like the shoulder straps) or I'll end up with a nut floating around and nothing to screw into and possibly have to remove the inner panels to sort.

     

    I'm using the car this weekend so it will have to wait until next week before I can pull out the seats and check.

  6. Car is a 1989 live axle.

     

    My current harnesses are a pair of Willans with 2" shoulder straps and are pretty old (the FIA label says ok to 1985) so I was going to replace them with a set that had 3" shoulder straps and are more up to date.

     

    I bought a set of Caterham/Luke from another club member and went to start the fitting process when I came across the problem that the original harness bolts look like they are 5/16ths and not 7/16ths. The bar they are bolted too (forward of the roll bar) is 1" box - I assume that is standard?

     

    So what are my options? Use a sleeve/bush with the 5/16ths? Drill out the box to take 7/16ths? (It doesn't have a captive nut under the bar, its uses a nylock). Or just leave well alone...
