Grandmaster Flatcap Posted December 29, 2012 Share Posted December 29, 2012 Help please chaps... I recently bought myself a SBFS half hood - all very nice - and fitted the back-to-back push the dot fasteners to the boot cover. Problem is the two studs on the skin of the car that these push the dots fasten onto are, well, chewed (is the only word I can thing to describe them). This is the first time I've had the boot cover off these studs. All the other studs appear to be fine, it's just these two (in fact the skin of the car is a little pushed in around the near-side stud. god knows what has happened to them). I managed to get the off-side popper onto the stud after much swearing and numbing of thumbs, but the near-side is a complete non-starter. Can some kind soul please tell me how to replace them, and what special tools if any I will need? Thanks in advance. Link to comment Share on other sites More sharing options...
Stationary M25 Traveller Posted December 29, 2012 Share Posted December 29, 2012 A sharp drill bit to drill the heads off the rivets that attach the poppers, then new poppers with the right size rivets, and a riveting tool. Link to comment Share on other sites More sharing options...
Member Jonathan Kay Posted December 29, 2012 Member Share Posted December 29, 2012 Did your half-hood come with replacement studs etc for those two? Mine did. The FAQs have a diagram of the new fitting and a video. Of course you still have to get the old stud off, as above. Jonathan Link to comment Share on other sites More sharing options...
SBD762 Posted December 30, 2012 Share Posted December 30, 2012 If you need a couple of Poppers, I will post some to you. Save buying a whole pack, you probably won't ever use again! BM me your address Cheers Steve Link to comment Share on other sites More sharing options...
Grandmaster Flatcap Posted December 30, 2012 Author Share Posted December 30, 2012 Thanks for the answers Does anyone know the rivet size? I'm at the outlaws so can't check the car, and I'm shopping on the interweb.

If I don't, I'll take you up on the kind offer. Link to comment Share on other sites More sharing options...
Grubbster Posted December 30, 2012 Share Posted December 30, 2012 Caterham use a specific pop rivet with a countersunk head which works a treat, I can send you a couple if you blatmail me your address. When you rivet them in you'll find that the head of the rivet gun won't reach inside the popper so you'll need to improvise - I used a small nut that would fit inside the popper between the head of the rivet gun and the head of the rivet.

Area Representative Richard Price Posted December 30, 2012 Area Representative Share Posted December 30, 2012 When fixing popper bases with the correct countersunk rivets, you also need to ensure that the nose of the riveting tool will sink inside hollow of the popper base rather than against the rim. I've had to modify a couple of riveting tools to achieve this. Link to comment Share on other sites More sharing options...

Grubbster Posted December 30, 2012 Share Posted December 30, 2012 Here you go, this is the countersunk rivet and popper base. The head of the rivet is well inside the popper so the nose of the rivet tool can't reach it - you can see I tried to file this bit down so it would go inside but it was too hard. So instead I use the little nut in between the tool and the head of the rivet, this is small enough to fit inside the popper so it means the rivet gets fixed in place properly. The washer is used if the rivet is going through a single ali sheet so that the load is spread. Link to comment Share on other sites More sharing options...
Member Jonathan Kay Posted December 30, 2012 Member Share Posted December 30, 2012 Just completed fitting my half-hood. Used the special poppers supplied with it that prevent the strap pulling off the popper above the wheel arch when you apply tension. On my car that stud was held by a screw rather than a rivet. I presume that's because there's a frame tube there. Jonathan Link to comment Share on other sites More sharing options...
Grubbster Posted December 30, 2012 Share Posted December 30, 2012 If the hole for a rivet hasn't been drilled already then a self tapper into a small hole is a good idea Link to comment Share on other sites More sharing options...
Stationary M25 Traveller Posted December 30, 2012 Share Posted December 30, 2012 As long as the head of the screw is small enough to fit inside the popper head and not protrude. Link to comment Share on other sites More sharing options...
Grandmaster Flatcap Posted January 4, 2013 Author Share Posted January 4, 2013 All sorted now - Thanks for the replies, and big thanks to the two Steves for the red cross parcels! What I hadn't spotted was that the profile of the male stud supplied by SBFS is different to the standard stud, so would have needed replacing even if they weren't already stuffed. N.

Clive Faulkner Posted February 6, 2013 Share Posted February 6, 2013 This is a job I've got to do in the near future. I've never had to use a riveting tool before and when I googled it came up with many over a wide price range. Can anyone give me a clue to what I would need to fit the two poppers to the car above the wheel arch? Thanks, Clive. Link to comment Share on other sites More sharing options...
Grandmaster Flatcap Posted February 6, 2013 Author Share Posted February 6, 2013 Clive, this is the one I bought here though not from that supplier. Following the instructions on here should get you sorted. Link to comment Share on other sites More sharing options...

Clive Faulkner Posted February 6, 2013 Share Posted February 6, 2013 Thanks Nigel. If that did the job for you then I'll get one of those. Cheers, Clive. Link to comment Share on other sites More sharing options...
Flipper69 Posted April 21, 2016 Share Posted April 21, 2016 Hello everybody, this is my first post and I'm not sure what the form is but I hope it's ok to resurrect this existing post. Unfortunately I am like a horse with a handbag wearing boxing gloves when it comes to matters practical so you'll have to bear with me but I am in sore need of some assistance please.Like Mr Mercer I have acquired an SBFS half hood and have successfully fitted the new studs to the boot cover but am really struggling fitting the new studs to the body of the car. I have invested in the Stanley rivet gun and have legion types of rivets but so far I have only succeeded in riveting the, erm, rivet to the car and riveting the rivet to the stud, but not riveting the stud to the car.Grubbster's helpful advice seems to solve the problem and I'm not sure whether there were originally photos attached to this string but I am so impractical that I still cannot work out what's required in terms of inserting the nut where.... Also, mention is made of a specific rivet - I've looked on Caterham's website but am unable to locate this. Any help or assistance will be gratefully received, thank you.

Member Jonathan Kay Posted April 21, 2016 Member Share Posted April 21, 2016 Welcome.Before you go any further have you identified the special directional fittings that take the straps just behind the doors? Are those the ones you're referring to in the last paragraph?Jonathan Link to comment Share on other sites More sharing options...
Flipper69 Posted April 21, 2016 Share Posted April 21, 2016 Thanks Jonathan.Yes, I have the Pull the Dot studs with the deeper rim which go with the uni-directional stud now fitted to the cover. In my final paragraph I was referring to a counter-sunk rivet which is mentioned earlier in the tread. Link to comment Share on other sites More sharing options...

Member Jonathan Kay Posted April 25, 2016 Member Share Posted April 25, 2016 I'm sure they could fix it but is it the problem with the reach of the nose of the rivetting tool? Posts #7 to #11?Jonathan Link to comment Share on other sites More sharing options...
